    摘要: Apparatus for measuring progressively the absorbance changes of a large number of aliquots from a plurality of different samples. The sample introduction, testing instructions, aliquot preparation, reagent dispensing, absorbance measuring and data recording all can be accomplished in a continuous mode of processing. Stat and batch operation also can be accomplished. The aliquots are in an array of cuvettes which is advanced slowly along a circular path. Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly along a similar circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that that cuvette completes one circuit of its path. The photometric detectors can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time. The radiant energy passing through each cuvette is received by the continuously moving photometer means, is converted electrically into a digitized value proportional to absorbance and is transmitted digitally from the moving assemblage of photometric detectors, cuvettes and electrical components to a stationary receiver. In one embodiment, the digital transmission is in the form of a pulsed train of light signals. In another embodiment, one or more slip rings transmit electric signals from the moving assemblage to the stationary portion. Suitable drive elements, sample and reagent storage and transfer mechanisms as well as cuvette laundry means may be provided as part of the complete apparatus.

    摘要: An optical timing and A/D conversion method and apparatus for converting analog signals obtained by movement of a plurality of reaction vessels relative to one or more beams of light from analog to digital signals. The sample signals are obtained each time a reaction vessel passes through a beam of light. The converted digital signals indicate the absorbance of the respective vessels and their contents. Each of the reaction vessels or cuvettes has translucent wall portions providing a radiation path therethrough for the light beams which may be monitored by photometer means in a chemical reaction analyzer. The vessels are repeatedly passed through the light beams of the photometer means as chemical reactions take place therein, the purpose being to monitor the changes in the reaction of the fluids therein by measuring the changes in the absorbance of the vessel and fluids. The sample interval of the analog signal is repeatable for each vessel for each light beam and may be shifted to select the best portion of the analog signal generated as the vessel passes through the particular light beam. The A/D conversion also may eliminate the dark sample or noise error between the light beams and the reaction vessels and may eliminate the variations in the sample signals caused by changes in the rate of relative movement between the beams and vessels and changes in the velocity of the rotating beam.
