Abstract
Apparatus for automatically measuring changing values of absorbance comprise a circular, absorption cell conveying system on which are disposed in order a multitude of absorption cells with samples injected therein, an optical measurement system disposed so that a measuring zone is positioned therewithin, said measuring zone is disposed in a predetermined position of said absorption cell conveying system, a measurement conversion system for encoding a measured value signal output from said optical measurement system with respect to each said absorption cell conducted successively into said measuring zone, a reference conversion system for encoding a reference value signal output from said optical measurement system, a synchronizing command system for generating a synchronizing signal upon sensing of the arrival of each said absorption cell at said measuring zone, and an arithmetic recording system including a microcomputer for inputting in parallel the output signals respectively from said measurement conversion system, reference conversion system and synchronizing command system and calculating a value of change in absorbance of each said absorption cell.
