Description
Technical field
The utility model relates to the separation method and the device therefor thereof that include with solid absorbent purified treatment liquid, particularly relates toAnd a kind of efficient pre-treatment separation equipment of sample that is applicable to chromatography determination.
Background technology
Food-safety problem is the major issue that is related to the people's livelihood, and the safety problem on the tip of the tongue is day by day serious, thus to Pesticide Residues,The detection of the chemical harmful substance such as residue of veterinary drug, mycotoxin and confirm imperative. At present, to Pesticide Residues, beastThe sample pre-treatments means that the chemical harmful substances such as medicine is residual, mycotoxin detect are more single, also concentrate on consolidating before the more than ten yearsPhase extraction column and centrifugal tubular type QUECHERS (QUECHERS (Quick, Easy, Cheap, Effective, Rugged, Safe),A kind of quick sample pretreatment technology for detection of agricultural products that latest development is got up in the world in recent years) two kinds of technology, do not haveBe improved, and solid-phase extraction column and centrifugal tubular type QUECHERS need to inject liquid clarifier inside, thereby operate numerousTrivial, detection efficiency is low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of syringe-type clarifier simple in structure, easy and simple to handle, this syringeFormula clarifier has enriched detection sample pre-treatments means, has strengthened widespread popularity, has greatly improved residues of pesticides and residue of veterinary drugDetect effect, improved detection efficiency.
The utility model syringe-type clarifier, comprises the syringe that is equipped with needle mount outside bottom, is provided with coaxial with it in described syringeAnd the piston type push rod of matched in clearance, described push rod can, along described syringe axially-movable, also comprise the sheet that is placed in syringe intracavity bottomShape sieve plate, described sieve plate top is placed with cleanser filler, offers some through holes on described sieve plate, and the aperture of described through hole is less thanThe particle diameter of described cleanser filler, also comprises plug, on described plug, is provided with depressed part, and described needle mount embeds described recessedIn the portion of falling into, stainless steel syringe needle inserts in needle mount.
The utility model syringe-type clarifier, described needle mount is hollow cylindrical flat mouth pipe, the shape of described depressed part and pinThe form fit of base, and described plug is plane along the axial side external surface of described syringe.
The utility model syringe-type clarifier, is provided with scale on described syringe.
The utility model syringe-type clarifier, described syringe, push rod all adopt PE material to make, and described plug is adopted made of plastic,Described sieve plate is super high molecular weight polyfluortetraethylene plate, and described push rod top is disk, and the external diameter of described disk is greater than described push rodBar footpath.
The utility model syringe-type clarifier is C18Modified silica-gel, ketjenblack EC, anhydrous magnesium sulfate, amido modified silica gel,The ethylene diamine-modified silica gel of N-propyl group, polyamide powder, resin anion (R.A.) particulate, resin cation particulate, neutral alumina.
The utility model syringe-type clarifier difference from prior art is that a cleanser filler fills in syringe inside, directlyExtracting liquid just can purify, and comparing existing solid-phase extraction column, splash into the design of flowing out from top quicker again. Existing residues of pesticidesSingle with detection of veterinary drugs in food sample pre-treatments means, clarifier of the present utility model has been broken this single form, has enriched detectionMeans have also solved the shortcoming of solid-phase extraction column and centrifugal tubular type complex operation, step complexity simultaneously, have greatly improved and have detected effectRate.
Below in conjunction with accompanying drawing, syringe-type clarifier of the present utility model is described further.
Brief description of the drawings
Fig. 1 is the front view of the utility model syringe-type clarifier.
Detailed description of the invention
As shown in Figure 1, the utility model syringe-type clarifier comprises syringe 1, and syringe 1 bottom is provided with needle mount outwardly11. In syringe 1, be provided with the piston type push rod 2 of and matched in clearance coaxial with it, push rod 2 can axially move back and forth along syringe 1.Above-mentioned syringe 1, push rod 2 all adopt PE material to make, and push rod 2 tops are disk, and the external diameter of disk is greater than the bar footpath of push rod 2,Promote push rod 2 to facilitate. Common clarifier push rod bottom is provided with glue head, while drawing organic solvent glue head be often corroded, dirtDye, and adsorb some solvents, this has just had a strong impact on the accuracy of testing result. Push rod 2 bottoms of this clarifier do not arrangeState glue head, effectively avoided above-mentioned burn into pollution problem, improved the accuracy of testing result.
Above-mentioned syringe 1 intracavity bottom is also provided with sheet sieve plate 3, and sieve plate 3 tops are placed with cleanser filler 5. This sieve plate 3 isOffer the super high molecular weight polyfluortetraethylene plate of some through holes, adopt the sieve plate 3 that this kind of material made can effectively reduce targetedThe absorption of compound. The aperture of the through hole on sieve plate 3 is less than the particle diameter of cleanser filler 5, and above-mentioned sieve plate 3 is set, and has played and has heldCarry the effect of cleanser filler 5, meanwhile, the particle diameter that through-hole aperture is less than filler 5 also effectively avoided cleanser filler 5 fromOn sieve plate 3, leak down testing result is had a negative impact. The shape of sieve plate 3, external diameter size and the form fit of syringe 1 and withThe variation of syringe 1 shape and changing, for example, when syringe 1 is cylinder, sieve plate 3 is disc-shaped, other shapes by that analogy,Do not enumerate herein. In addition, while detection for convenience, measure appropriate amount of fluid, can on syringe 1, scale be set, for example, canTo be set to the different sizes such as 20ml, 15ml, 10ml, 5ml, 2ml.
Clarifier of the present utility model also comprises that one is adopted plug made of plastic 4, is provided with towards needle mount on plug 411 depressed part 41, the form fit of the shape of depressed part 41 and needle mount 11. During in the present embodiment, needle mount 11 isHollow round column shape flat mouth pipe, depressed part 41 is also cylindrical, needle mount 11 embeds in depressed part 41, like this, in the middle of plug 4The depressed part 41 of offering just in time covers needle mount 11 completely, played good sealing function, has avoided needle mount 11Pollute. Stainless steel syringe needle 6 inserts in needle mount 11. When use, stainless steel syringe needle 6 is assemblied in needle mount 11, adoptsExtract extract to be clean to syringe-type clarifier with suction. Meanwhile, plug 4 is along the axial side external surface of syringe 1For plane, to clarifier entirety is stood on to desktop. Facilitate the placement of clarifier to arrange. Above-mentioned needle mount 11, depressed part41 shape is cylindrical being limited to mention in the present embodiment not, easily expects but can rationally be deformed into other those skilled in the artShape, do not enumerate herein.
Above-mentioned cleanser filler 5 is C conventional in residues of pesticides and detection of veterinary drugs in food18Modified silica-gel, ketjenblack EC, nothingWater magnesium sulfate, amido modified silica gel, the ethylene diamine-modified silica gel of N-propyl group, polyamide powder, resin anion (R.A.) particulate, cationResin particle, neutral alumina etc.
Compare existing centrifugal tubular clarifier, clarifier of the present utility model need not move into liquid in clarifier, but directlyExtract, thereby saved this link of immigration liquid, and there is no centrifugal process, greatly saved the operating time.
Above-described embodiment is described preferred embodiment of the present utility model, not to of the present utility modelScope limits, and is not departing under the prerequisite of the utility model design spirit, and those of ordinary skill in the art are to the utility modelTechnical scheme various distortion and the improvement made, all should fall in the definite protection domain of the utility model claims.
