摘要： A method and apparatus for testing a sample by means of luminescent reaction to detect reactive materials therein. A light-transparent filter is provided to filter the sample and to carry the residue to a reaction position. A light-transparent surface is provided to carry a reagent to the reaction position. Both surfaces are brought into mutual contact in a region between two photodetectors, which thereby detect the resulting luminescent reaction to provide an indication of the quantity of reactive material present in the sample.

摘要： An improved apparatus for testing a sample by means of luminescent reaction to detecting reactive materials therein. A translucent ribbon of filter material is provided to filter the sample and to carry the residue to a reaction position. A translucent surface is provided to carry a reagent to the reaction position. Both surfaces are brought into mutual contact in a region between two photodetectors, which thereby detect the resulting luminescent reaction to provide an indication of the quantity of reactive material present in the sample. An improved pinion roller advances the ribbon of filter material in a reliable fashion.

摘要： An improved method for detecting very low concentrations of luminescent reactive molecules from microbial cells in samples of fluids and degraded solids is disclosed. A sample containing microbial cells is treated to eliminate substantially all nonmicrobial material. The microbial cells are then caused to rupture and form a thin film positioned in the vicinity of a photodetector. An appropriate reagent contacts the thin film and the resulting photon emission is observed by the photodetector through an optical filter means which selectively restricts the wavelength of photons which are permitted to pass from the sample to the detector. The strength of the luminescence within the permitted wavelength is measured and recorded as an indication of the concentration of microbial cells in the sample.

摘要： An improved apparatus for testing a sample by means of luminescent reaction to detect reactive materials therein. A ribbon of filter material, which may be translucent or opaque, is provided to filter the sample and to carry the residue to a reaction position. A translucent surface is provided to carry a reagent to the reaction position. Both surfaces are brought into mutual contact in the optical vicinity of a photodetector, which thereby detects the resulting luminescent reaction to provide an indication of the quantity of reactive material present in the sample. An improved pinion roller advances the ribbon of filter material in a reliable fashion. In an alternative embodiment, the ribbon of filter material is used without the translucent surface.
