Definitions
- This invention relates to light photon detecting apparatus and a filter delivery and/or collection system therefor.
- the present invention seeks to provide light photon detecting apparatus which will speeden up the checking process and in particular seeks to provide a filter delivery and/or collection system for such apparatus.
- a filter delivery and/or collection system for use with light photon detecting apparatus, comprising an upstanding tube for receiving filter papers each held in an individual holder and two toothed wheels disposed adjacent to the lower end of the tube and angularly movable about horizontal or substantially horizontal axes to deliver filter papers to a surface below the tube or to receive filter papers and retain them in the tube.
- light photon detecting apparatus comprising a filter paper delivery system ⁇ for delivering filter papers onto an indexable support surface, an impregnating device for impregnating the filter papers with a sample to be checked, an injection device for injecting reagents onto the filter papers, one or more light photon detectors for detecting light photons emitted from the reagent injected samples, and a filter paper collection system for collecting filter papers from the suppo ⁇ surface.
- Figure 1 is a fragmentary, diagrammatic, perspective view of one embodiment of a filter delivery and/or collection system according to the first aspect of the invention
- Figure 2 is a diagrammatic sectional view through the filter delivery and/or collection system shown in Figure 1 .
- Figure 3 is a schematic plan view of one embodiment of light photon detecting apparatus according to the second aspect of the invention.
- the filter delivery and/or collection system shown therein is chiefly intended for use with light photon detecting apparatus of the type shown schematically in Figure 3.
- the delivery and/or collection system comprises a plurality of upstanding tubes 10, typically four in number, spaced apart above a circular suppo ⁇ surface 11.
- the delivery and/or collection system also comprises two toothed wheels 12 mounted immediately below each tube '10.
- the toothed wheels are diametrically opposed to one another with respect to each tube 10 and are angularly movable about respective horizontal axes which are parallel to one another.
- the delivery system in particular also includes a mechanism (not shown) fop indexing the two wheels 12 in synchronism with one another and a control circuit (also not shown) for indexing the wheels 12 as and when required.
- each tube When used as a filter delivery system, each tube contains a stack of sterile filter papers 13 each of which is held in an individual holder 14.
- Each holder 14 comprises two annular parts 15 and 16 and the filter paper 13 is secured between the two parts.
- the external diameter of the part 15 is smaller than the external diameter of the part 16 so that when the holders 14 are stacked one upon another an annular recess is provided between the larger diameter parts 16 of two adjacent holders 14 for receiving teeth of the toothed whe s 12.
- the two toothed wheels 12 When serving as a filter delivery system, the two toothed wheels 12 are indexed in opposite angular directions and, as shown in Figure 2, the left hand wheel is indexed in a clockwise direction and the right hand wheel is indexed in a counter clockwi ⁇ direction. This will cause a filter paper 13 together with its holder 14 to drop onto the circular supporting surface 11.
- the tubes 10, when full of filter papers 13, can be provided with removable seals at their lower ends.
- the filter paper 13 and holder 14 are raised above the supporting suiface 11 by a plunger or ram (not shown) mounted in the supporting surface 11.
- the toothed wheels 12 will simply operate as ratchets or can be driven in synchronism with the rising plunger or ram.
- FIG. 3 there is shown therein light photon detecting apparatus comprising a circular carousel 20 which can be indexed by a drive unit (not shown).
- the apparatus has five stations.
- a filter paper delivery system 21 which may be similar to that described with reference to Figures 1 and 2.
- an impregnating device 22 for impregnating the filter papers with a water sample or an air sample.
- an injection device 23 for injecting reagents such as, for example, detergent for cell disruption and luciferin-luciferase for reaction with released ATP molecules and/or other chemicals as appropriate for the test to be carried out.
- a multiple light photon detector or a plurality of single photon detectors 24 the design of which can be based on the design of the lighi photon detector described in GB-A-22i8803, for detecting light photons emitted from the reagent injected samples.
- a filter paper collection- system the design of which can be based on the design of the lighi photon detector described in GB-A-22i8803, for detecting light photons emitted from the reagent injected samples.
- the tubes 10 of the filter delivery and collection system may be removable from their positions above the carousel 20 so that empty tubes from the delivery system can be used in the collection system.
- This apparatus will allow continuous monitoring of samples with time intervals regulated by software. It also provides a facility to carry out comparative tests, simultaneously and or replicates of the same test.
