Definitions
- the present invention relates to the analysis of functional fluids, including a method and apparatus for the analysis of functional fluids.
- the functional fluids that are analyzed include lubricating fluids and fuels, such as those used in automobiles, trucks, engines, turbines, pumps, transmissions, differentials and the like.
- methods and apparatus for testing the condition or identity of a fluid include chromatography and chemical analysis. These methods generally require controlled conditions and specialized training.
- Other methods and apparatus for assessing the quality of a used fluid include placing a measured amount of fluid upon an absorbent material, heating the sample and awaiting dispersion of the sample. The amount of undispersed sample may then be measured and rated quantitatively. These methods and apparatus require significant controlled conditions, including measurement of the fluid sample volume, the use of a template to measure and rate the quantity of undispersed the sample. Additionally these methods can include heating of the sample, and awaiting dispersal of the sample.
- Markers have been used to identify fluids. Proton accepting chemical substances, that at a solution concentration of below about 50 milligrams per liter, impart little or no significant color to organic solvents, have been proposed as markers, or taggants, especially for petroleum-derived fuels. The marker is dissolved in a liquid to be identified, and then subsequently detected by performing a chemical test on the marked liquid. Markers are sometimes employed by government agencies to ensure that the appropriate tax has been paid on particular grades of fuel. Oil companies also mark their products to help assist in identifying diluted or altered products. These companies often go to great expense to make sure their branded petroleum products meet certain specifications, for example, volatility and octane number, as well as to provide their petroleum products with effective additive packages containing detergents and other components. Consumers rely upon product names and quality designations to assure that the product being purchased is the quality desired. Thus, it is important to be able to identify a marker in a petroleum product.
- the presence of a marker substance is detected and optionally quantified by extracting the fuel with an immiscible aqueous or significantly aqueous solution of an acid substance, the precise nature of which can be varied according to the characteristics of the marker substance.
- the acid reacts with the basic compound to produce a readily visible, more or less intensely colored cation, that is dissolved in the aqueous acid phase.
- This method is disclosed in U.S. Pat. No. 5,145,573.
- a method has been disclosed in WO 03/078551 A2 where the acidic substance has been applied to a test strip. The test strip is dipped into the oil and diazo-type marker reacts with the acidic substance in the test strip and changes color.
- the quantity of marker substance in the extract may also be measured, for instance, by visible light absorption spectrophotometry, the results of which are then compared with a reference standard to determine the original concentration of basic marker in the fluid. It may be necessary to make repeated, typically two or three, extractions of the fluid to recover the entire amount of marker originally present in order for complete quantification. Additionally, the extracted, separated phase is classifiable as a hazardous waste and presents problems of safe and lawful disposal, especially when examinations are made "in the field.” Furthermore, the fluid with which was tested may be contaminated, making return to its original source undesirable and presenting additional waste disposal problems.
- the present invention will rapidly indicate the condition of a functional fluid such as lubricating oils, engine oil, transmission fluids, greases, gear oils, hydraulic fluids, metalworking fluids, antifreeze fluids, coating system fluids, cooling systems fluids, farm tractor fluids, transformer fluids, fuels such as diesel, gasoline, biofuels, emulsified fuels, and the like in the field.
- a functional fluid such as lubricating oils, engine oil, transmission fluids, greases, gear oils, hydraulic fluids, metalworking fluids, antifreeze fluids, coating system fluids, cooling systems fluids, farm tractor fluids, transformer fluids, fuels such as diesel, gasoline, biofuels, emulsified fuels, and the like in the field.
- Many owners/operators of equipment that depend on these functional fluids currently depend on standard guidelines, such as hours or mileage, to determine the appropriate interval
- test functional fluids comprising a test medium treated with a chemical indicator or developing agent upon which the fluid is placed with accompanying descriptive text, and instructions.
- the present invention provides a method to analyze the condition of a functional fluid comprising:
- the visual indicia shows a depiction of a fluid which is in an acceptable condition and one where the fluid is in an unacceptable condition or a depiction of a marked and unmarked fluid.
- a greater range of conditions shown by the visual indicia will permit the test sample to be more closely approximated to the comparison examples by the kit user.
- the invention further provides a test kit for the analysis of functional fluids comprising a chemically treated test medium and visual indicia depicting the functional fluids disposed upon the test medium.
- the invention further provides printed instructions, also included, to summarize the steps for use of the kit, which generally correspond to the description of the method given below.
- the present invention further provides a novel and improved method for detecting marker substances.
- the method for the analysis of the quality of the functional fluid for example lubricating oil is effective but simple, and has the advantage of quickness and ease of use in uncontrolled conditions by untrained personnel.
- the invention provides a method to analyze function fluids which include lubricating oils, engine oils, transmission fluids, greases, gear oils, hydraulic fluids, metalworking fluids, antifreeze fluids, cooling system fluids, coating system fluid, farm tractor fluids, transformer fluids, fuels such as diesel, gasoline, biofuels, emulsified fuels, and the like.
- Figure 1 is a drawing plain view showing application of the test sample to the test medium using a dipstick from an engine
- Figure 2 is a drawing plain view showing dispersion of the lubricating oil sample upon the test medium for four fluids.
- the present invention provides a method and device such as a kit for analyzing the condition of functional fluids.
- the functional fluids comes from innumerable sources, including internal combustion engines, turbines, transmissions, differentials, pumps, metalworking operations, cooling systems, and the like.
- the functional fluid includes organic solvent based, aqueous based and combinations thereof.
- the functional fluid includes lubricating oil, engine oil, gear oil, transmission fluids, hydraulic fluids, metalworking fluids, antifreeze fluids, cooling system fluids, coating system fluids, farm tractor fluids, transformer fluids, greases, fuels such as diesel, gasoline, biofuels, emulsified fuels, and the like.
- Figure 1 is a plain view showing application of the test sample, 2, to the test medium, 1 , using a dip stick, 3, from an engine.
- Figure 2 is a plain view showing dispersion of the lubricating oil sample 2 upon the test medium 1 for four fluids: an engine oil in new condition, A; an engine oil in good condition, B; an engine oil that is acceptable within the normal range for typical engine oil, C; and an engine oil at the limit of useful life requiring an oil change, D.
- the different shading in the various drawings represents a progression in the degree of indicator color from the various samples of oil. Application of a new oil on the treated test medium, A, results in a dramatic color change of the indicator, 4.
- the functional fluid to be tested is placed upon an appropriate test medium.
- This test medium can be comprised of absorbent material, nonabsorbent material and combination thereof.
- the test medium includes paper, cellulosic material such as cellulose, cellulose nitrate, cellulose acetate, wood, chromatography paper, filter paper, polymeric fibers, natural fibers, finely woven fabrics, metal, glass, glass micro fiber, sintered glass, silica and/or alumina coated surfaces such as thin layer chromatography plates, plastic, plastic laminated material, composites and combinations thereof.
- the test medium must be capable of receiving a sample of the functional fluid.
- the test medium should be compatible with the indicator and/or developing agent.
- Other absorptive/adsorptive materials, having the, general physical properties and characteristics of chromatography paper are also be acceptable.
- the preferred test medium includes "Whatman" white colored chromatography paper or filter paper in the form of an easy to dispense and use wipe.
- absorptive paper such as chromatography paper is preferred, in particular for lubricating oil samples.
- Light colored chromatography paper provides a consistent background which contrasts well with the functional fluid, provides for a more conspicuous color change and has the proper adsorptive affinity for the various components of an oil. For example, the coloration of the indicator becomes more pronounced over time on the outer edges of the sample spot on the paper as the indicator colored portion of the mixture is swept along with the mobile phase (oil and solvent) faster than the darker components of the used oil, such as sludge. This is due to the differences in adsorptive affinity for the paper. This difference in affinity becomes important as the concentration of sludge in the oil sample increases over the service life.
- test medium may need to be varied, whether the test medium is chromatography paper or other type of paper, polymeric fiber material or nonabsorbent material like glass, plastic or metal.
- the test medium may differ in its adsorptive affinity for the various components in the particular fluid, porosity, density, wicking ability, or other physical characteristics such as color.
- test medium is unimportant, so long as it is of an effective size to permit dispersion of the functional fluid sample, but small enough to be economical and limit waste.
- the test medium may be provided in a hermetically sealed envelope or package made of plastic or some other suitable material. The package could be designed to be held in the hand and opened on one side exposing the treated test medium for convenient usage yet protecting the users hand from contacting the test fluid or the indicator system adding to the convenience of the unit. Additionally, the test medium could be provided in a multi-unit dispenser tub for high volume applications in for example an automotive service station.
- Indicator reagents for the purposes of this invention are substances that enable the state of a chemical system to be characterized.
- the indicator includes a variety of acid/base indicators, metal indicators, redox indicators, dyes, absorption indicators and the like. Combinations of indicators may be used.
- indicator depends on the type of fluid being tested and/or the parameters being determined such as the concentration of acidic or basic components, presence or concentration of metals, oxidative/reductive potential, identity markers or the presence of specific components to name a few.
- “lock and key” type indicators are also included wherein a "lock”, a material soluble in the fluid and stable to the conditions of use, is added to the fluid and an indicator, or "key”, is chosen to specifically detect the lock. This concept may also take the form where a determined functional additive, present in the fluid for performance reasons, is targeted and a "key" is selected to indicate the presence of the "lock”.
- the indicators function by a variety of mechanisms both in how the specific parameter is determined in how the indicator responds. Examples of indicator responses include color changes as seen through visual colorimetry, photometry, fluorescence, chemiluminescence and the like. Combinations of indicator responses may be used.
- the color of the indicator is chosen depending on the type of fluid being tested and/or the level of degradation of the fluid. Certain colors contrast strongly to the usual color of the fluid which is preferred. The choice of a suitable color may be determined by a particular application. For example, automatic transmission fluid for passenger cars is colored red for identification purposes. It would be inappropriate to use an indicator that turns red to indicate an unacceptable condition in the fluid.
- Acid/base (pH) indicators include Malachite Green, Brilliant Green,
- Methyl Green Picric acid, Cresol Red, Crystal Violet, Metanil Yellow, m- Cresol Purple, Thymol Blue, p-Xylenol Blue, Thymol Blue sodium salt, Quinaldine Red, Tropaeolin 00, 2,6-dinitrophenol, Phloxine B, 2,4- dinitrophenol, 4-dimethylaminoazobenzene, Bromochlorophenol Blue, Bromophenol Blue, bromophenol blue sodium salt, Congo Red, Methyl
- Absorption indicators include Fluorescein, Eosin, Phloxine, Rose Bengal and Rhodamine 6G and the like. Combinations may be used.
- Metal indicators include Alizarin Complexone, Alizarin S, Arsenazo III, Aurintricarboxylic acid, 2,2'-Bipyidine, Bromopyrogallol Red, Calcon (Eriochrom Blue Black R), Calconcarboxylic acid, Chrome Azurol S, Chromotropic acid, disodium salt, Cuprizone, 5-(4-Dimethylamino- benzylidene)rhodanine, Dimethylglyoxime, 1 ,5-Diphenylcarbazide, Dithizone, Eriochrome Black T, Eriochrome Blue SE, Eriochrome Blue Black B, Eriochrome Cyanine R, Fluorescein Complexone, Glyoxalibis(2- hydroxylanil), Hematoxylin, 8-Hydroxyquinoline, 2-Mercaptobenzothiazo

- Diphenylbenzindine-disulfonic acid o-Dianisidine, 3,3'-Dimethylnaphthidine, 3,3'-Dimethylnaphthidine disulfonic acid and the like. Combinations may be used.
- Marker substances include diazo dyes, anthraquinone dyes and the like, metals, metal salts, metal oxides, metal coordination complexes and the like or other substances compatible with the lubricant. It may be beneficial for the marker substance to be stable to the service conditions of the fluid, but it is not necessary. In general marker substances are used to identify new fluids. In some cases however, it could be useful to validate the identity of a fluid for, as an example, warranty claims. In this case the marker would need to survive and be detectable after experiencing the typical operating conditions of the fluid. Combinations of these substances may be used.
- Developing agents are substances that will make conspicuous the presence or absence of a marker substance. Developing agents could include mineral or organic acids and the like, basic substances, oxidizing agents, reducing agents, chelating agents and the like. Combinations of developing agents may be used.
- the preferred indicator is Alizarin for lubricating oils.
- the present invention may use combinations of indicator reagents, combinations of developing agents and mixtures thereof.
- Analysis in particular qualitative analysis of the reacted test sample is accomplished by visual inspection of the reacted test sample using the (provided) visual indicia as a guide. Analysis occurs after an effective period of time to allow for the reaction between the components of the fluid and the indicator. Generally the time for reaction is in the range of about 1 sec. to about 30 mins, in another embodiment about 1 minute to about 15 minutes and in another embodiment about 1 minute to about 5 minutes.
- the visual indicia include an artistic rendering, a reproduction of a photograph of a functional fluid in various conditions, color key, and the like. Combinations of visual indicia may be used.
- the visual indicia generally include one representation, two representations and more than two representations of the functional fluid disposed upon the test media.
- the preferred visual indicia is one in an unacceptable condition and one in acceptable condition or a marked and unmarked fluid or the like. In one embodiment, it is preferred for the visual indicia as shown in Figure 2.
- the engine oil has the characteristics of the engine oil in excellent condition; an oil in good condition, acceptable within the normal range for typical engine oil; and an engine oil at the limit of useful life requiring an oil change.
- a descriptive text corresponding to each of these examples may be provided in the kit.
- the visual indicia depicted be dispersed upon the same or similar medium provided in the kit, to assure that the kit user compares the sample to be tested to examples produced under similar conditions. It is to be understood that a different number of indicia than shown in Figure 2 may be provided.
- the test medium can be dry or wet. In one embodiment where the test medium is wet it is due to the use of a solvent on the test medium.
- Suitable solvents include aliphatic, unsaturated and aromatic hydrocarbons, alcohols, glycols, glycol ethers, lower alcohols, such as methanol, ethanol and propanol, ethers, esters, amides, water and the like. Combination of solvents may be used.
- the solvent is used in the range of about 1 % to about 99.9%, in one embodiment about 5% to about 98% and in another embodiment about 1% to about 95.5% of the indicator solution.
- the solvent used depends on the type of fluid being tested. Combinations of solvents are also useful when the indicator or developing agent, depending on the application and type of analysis desired, is not soluble in the fluid.
- solvents or combinations of solvents which present a desirable combination of properties including good solvency power and miscibility with the fluid and the indicator or marker or development agent, low vapor pressure at ambient temperatures, high flash points and the like.
- the method comprises the steps of (a) obtaining a sample of a functional fluid, (b) placing the sample upon the test medium, (c) waiting for an effective period of time to allow for the reaction between the components of the fluid and the indicator or developer, d) making a visual determination of the test medium using the printed instructions and/or comparative visual indicia depicting the functional fluid in various conditions as a guide for qualitative determination.
- the sample may be taken at any time before, during or after operation of the engine or equipment.
- the functional fluid sample can be new, used or combinations thereof.
- the apparatus is comprised of a package that can be sealed containing the chemically treated test medium in either a wet or dry state and includes written instructions and a set of visual indicia depicting samples of the fluid disposed upon a test medium printed in color on the package with descriptive text.
- the visual indicia should show a depiction of the fluid which is in an acceptable condition and one of the fluid > in an unacceptable condition or with and without a marker substance.
- the functional fluid is an engine oil.
- the engine oil sample under ordinary circumstances may be obtained using a dipstick provided as a part of the engine, transmission or other equipment under lubrication. The user will withdraw an amount of oil along with the dipstick and the dipstick may then be wiped on the test medium or the oil which will collect into a drop at the end of the dip stick may then placed upon the test medium. Typically, less that 1 milliliter of oil is necessary for the analysis.
- the user determines whether or not a color change occurred, and refers to the visual indicia as a guide. The user may consult the descriptive text accompanying the example selected to determine the condition of the functional fluid.
- Example 1 This example tests the quality of passenger car engine oil and consists of a test medium of Whatman filter paper, which has been soaked with a solution of ethanol or isopropanol (90% w/w), lauryl alcohol
- pH indicator (0.1 % w/w) and pH indicator (0.1 % w/w).
- the pH indicator used is Alizarin
- a used oil sample is placed on the wet filter paper and the basic additives (quantified as the TBN or Total Base Number, typically measured by ASTM D4739) of the oil react with the pH indicator inducing a color change from yellow to purple, with the indicator listed above, to a degree depending on the level of TBN.
- the intensity of the color change is reduced as the TBN drops over the service life of the oil until no purple color is apparent indicating the fluid has reached its maximum life. (See Table 1)
- Table 1 demonstrate that an oil can be analyzed by visual indicia depicting the quality of the oil, as the brown color with no purple at 6000 miles indicates the condition of the oil.

La présente invention concerne un procédé pour analyser la condition d’un fluide fonctionnel consistant à : (1) obtenir un échantillon du fluide utilisé ; (2) placer l’échantillon du fluide dans un milieu d’essai ; (3) faire réagir le fluide avec un indicateur dans le milieu d’essai ; (4) analyser visuellement les résultats du réacteur résultant dans la détermination de la condition du fluide. En outre un appareil pour analyser les fluides fonctionnels est décrit dans la forme d’un milieu d’essai consistant en un matériau absorbant ou non absorbant qui a été traité avec un indicateur chimique, un marqueur ou un développeur ou produit réactif de détection sur lequel un échantillon du fluide à tester est placé. Les composants dans le milieu d’essai traité réagissent avec les composants dans le fluide d’essai fournissant une indication visuelle, par exemple, un changement de couleur, pour juger la condition, la présence d’un marqueur ou autre paramètre du fluide. Le fluide fonctionnel peut être soit un lubrifiant, du combustible ou autre fluide fonctionnel provenant de sources innombrables, comprenant les moteurs à combustion interne, les turbines, les transmissions, les différentiels, les pompes, les opérations de métallurgie, les systèmes de refroidissement, etc., et être soit un solvant organique ou un solvant aqueux.
