  • Each lower compartment has a bottom wall 28, exterior side walls 30, 32 and 34 and interior wall 36.'The wall portions of compartments 24 and 26 terminate in a horizontal'flange 38 which encircles the outer perimeter of the two compartments and holds them together as a dis tinct unit.
  • Bottom wall 28 is parallel with horizontal flange 38 with walls 30, 32, 34 and 36 being perpendicular thereto, the five walls thus defining a rectangular volume having slightly rounded edges and corners.
  • the rectangular volume does not extend all the way from bottom wall 28 to flange 38 but terminates intermediate these two elements.
  • the lines of termination of the rectangular solid along each wall define a plane which is parallel to'the plane of horizontal flange 38.
  • walls 32 From-this plane the walls diverge upwardly and outwardly as at 30', 32, 34' and 36' until they intersect with horizontal flange 38 to define a rectangular opening beneath the plurality of reagent storage chambers when upper section 14 is in position on flange 38.
  • walls 32' terminate in a short leg 32" just prior to its intersection with flange 38, leg 32" being perpendicular to flange 38. If desired this leg can be omitted whereby walls 32 will diverge upwardly and outwardly from the plane at the top of the rectangularvolume until they intersect with flange 38.
  • the shape of the opening is not critical as long as it will not interfere with the introduction of sample and reagents into the lower compartment.
  • the sloping walls channel all materials downward toward the bottom of the reaction compartment.
  • Interior walls 36 extend to the plane of horizontal flange 38 and are connected to each other at line 40 thereby forming a distinct barrier between c0mpartments 24 and 26.

  • Flanges 38 and 44 are sufficiently wide along thewider portions 45 so that a code area 46 can be provided hetween inner bond 48 and outer bond 40.
  • Typical codes include binary codingin the form of light and dark areas, magnetic coding, etc.
  • the storage cham In the embodiment of FIGURES 1-4, the storage cham.
  • bers 16 and 18 are shown withmeans in the form of ribs whichfencircle each storage chamber and holdthe reagent tabletstherein.
  • the ribs are so positioned as .to maintain a small gap between the reagent tablets. This prevents tablet contact which might, over a long period of storage. result in a chemical reaction which might adversely affect the chemical properties of the stored reagents. Any number of reagent tablets can be stored in this manner.
  • the tablets are merely snapped into place and remain there until the application of force to the top of the storage chamber causes the tablets to be dispensed therefrom.
  • the first or lower tablet can be dispensed without having to dispense the upper tablet. That is, the force must be just sufiicient to displace the upper tablet from its storage zone within the chamber and transfer it to the storage zone previously occupied by the lower tablet.
  • the lower tablet is ejected from its storage zone into the lower compartment in lower section 12.
  • both tablets can be ejected simultaneously.
  • container is taken from a supply magazine and passed to a sample addition station where the proper amount of sample diluted with distilled water is accomplished by injecting the sample solution through a needle which has been inserted through upper section 14. Preferably, this insertion is made at a point which will not cause undue rotation of the supported container.
  • the sample-holding container is then passed to a reagent addition station where the application of a pushing force on each storage chamber causes the reagent tablet or tablets stored therein to be emptied into the appropriate compartments.
  • Reagent addition can be done in one opera tion or it can be done sequentially as is necessary to complete the analytical procedure. If done sequentially, the addition can be done during or after incubation.
  • reagents can be added any time prior to final detection as determined by the particular analytical procedure utilized.
  • Container 10 is passed to a mixing station where it is maintained for a time sufiicient to ensure the dissolution of all solid materials in the liquid contained in the lower compartments.
  • the container next passes to an incubation station where appropriate reaction conditions are imposed upon the materials within the container for a time sufficient to complete the desired reaction which is then measured at a detection station. It is not necessary that the mixing and incubation stations be separate and distinct as it is contemplated that these operations may be performed in a single station.
  • light of appropriate wavelength is passed from a light source through the reaction mixture to detection means situated on the opposite side of the reaction mixture from the light source.
  • the amount of light transmitted (or, conversely, the amount of light absorbed) at the testing wavelength will be representative of the amount of the constituent under analysis in the test solution.

  • one compartment there is providing a solution of the material being tested with all the reagents which will bring the reaction mixture to the desired point for analysis.
  • the other compartment contains a solution of the material being tested in the absence of reagents.
  • one or more reagents can be added to this latter solution, provided the reagents do not carry the reaction to completion or do not adversely aifect, in any other way, the optical analysis.
  • This latter solution is called a critically incomplete blan and will enable the analytical system to compensate for the effects of the sample and the reagents added thereto.
  • standard solutions are passed through the detection mechanism at intervals so that the latter can adjust for deviations which occur during operation.
  • a disposable container having three compartments, and the plurality of storage chambers associated with each compartment where reagents need be added is provided for use with a triple-beam detection mechanism.
  • the standard solution can be injected into the disposable container at any point in the system prior to optical analysis and will obviate the need for passing distinct disposable container holding standards through the system.
  • standard-containing tablets can be stored in the upper section, dispersed into the lower compartment and diluted to give the desired concentration.

  • light from the light source and light which has passed through the reaction mixture can be conducted to the disposable container and the detection means, respectively, through light conduits which are pressed against an opposite pair of rigid walls which comprise a portion of the lower compartment.
  • the optical path is defined by the distance between the opposite walls of the lower compartment against. which the light conduits are pressed. Since it is preferred to maintain this optical path constant for all like analytical procedures, strict production requirements must be met in the produc tion of disposable containers having rigid lower compartment walls.
  • FIGURE 5 This optional form of optical analysis is shown in FIGURE 5 wherein a disposable reaction container 60 having flexible walls 30 and 34 has light source means and detection means pressed against opposite walls of the lower reaction compartment.
  • light conduits 62 and 64 are pressed against walls 30 and 34, respectively, of each lower compartment.
  • Conduit 62 is connected at the opposite end to a light source (not shown) which can be filtered to provide light of a desired wavelength or wavelengths.
  • Conduit 64 directly opposite conduit 62, is connected to an appropriate detection means (not shown) for monitoring the intensity of the light passed through the liquid mixture in the lower compartment.
  • conduits 62 and 64 are moved toward each other whereby the flexible walls of the compartment will deform and assume the position as shown by the dotted lines thus defining a fixed optical path L between the interior sides of deformed walls 30 and 34 and through the reaction mixture.
  • a fixed optical path L By providing a fixed optical path L in this manner, it is easier to mass produce the disposable container as a certain critical feature, the optical path, has been eliminated as a strict production requirement.
  • the optical path defining means is now built into the detection station and, as would be expected, significantly less detection stations should be produced than disposable containers. Since a fixed optical path is defined by the detection station and will be the same for each container passing therethrough, highly accurate and reliable data can be obtained with this system.
  • the disposable reaction container 10 as shown in FIGURE 5 can be used in conjunction with a double-beam detection mechanism, as described above in relation to FIGURES 1-4.

  • FIGURE A further embodiment of the storage chamber and upper section of the present invention is shown in crosssection in FIGURE wherein upper section 14 has a storage chamber 66 having three tablets T therein.
  • This embodiment differs from the earlier embodiment, however, in that the wall of the storage chamber 66 is tapered so that larger diameter tablets can be stored in the lower portion of the storage chamber than at the middle or upper portion. With prior designs, it was always necessary to store tablets of the same diameter. Yet, for many of the difficult-to-tablet recipes there is an optimum thickness-to-diameter ratio.
  • the ribs are so positioned as to maintain a small gap between the reagent tablets. This prevents tablet contact which might result in a chemical reaction which would adversely affect the chemical properties of the stored reagents.

These detents are adapted to maintain a reagent tablet in position in a storage zone within the storage chamber. As many sets of detents can be provided as are necessary to store the desired plurality of tablets within the storage chamber. With the exception of the substitution of the detents for the encircling ribs, the upper section of FIGURE 6 is otherwise similar to the upper section of FIGURES 1-3.

The shape of the storage recess is not critcial as long as the magnetic stirring bar can easily drop into the recess when the bar is not in use.
  • the rotation of the magnetic bar within the disposable container creates a vortex and by regulating the rotational speed of the magnetic stirring bar it is possible to thoroughly mix all the reagents with the sample as well as to clean the walls of the reaction compartment and the storage chambers of undissolved reagents. This insures that all reagents are present in the reaction mixture in proper amounts.
  • the stirring bar Upon completion of the mixing operation, the stirring bar will settle into its storage recess out of the way of optical analysis which proceeds through the side walls forming the rectangular volume of each reaction compartment.
  • An exemplary stirring bar comprises a small cylindrical section of stainless steel Wire.
