Apparatus for simultaneously measuring lactic acid and pyruvic acid

Abstract

Abstract PURPOSE:To measure the concentration ratio between lactic acid and pyruvic acid simply in a short time and at a high accuracy, by calculating and display the ratio between the concentrations of lactic acid and pyruvic acid from outputs of two enzyme electrodes for the measurement of lactic acid and pyruvic acid respectively. CONSTITUTION:A sample is shunted and fed to mixers 27 and 27 with a pump 28 from a sample injection port 25 and mixed with a buffer liquid being fed with a pump 22 via a heating coil 24 from a bottle 21. The sample and the buffer liquid are mixed throughly with a mixing coil 29 and after the removal of bubbles with a bubble remover 30, a part thereof is sent to enzyme electrodes 32 and 32 with a pump 33 to measure the concentrations of lactic acid and pyruvic acid with the two enzyme electrodes 32 and 32 for measuring lactic acid and pyruvic acid respectively. The ratio of both the concentrations is calculated and displayed through a microcomputer.
