Automatic measurement of co2evolution in multiple samples in small chambers

Abstract

As CO2is a universal product of living organisms, the measurement of CO2evolution is important for analyzing biological activity. Recently, the use of an infrared gas analyzer (IRGA) for CO2measurement has facilitated the assessment of soil biological activity, especially under laboratory conditions. The IRGA method for CO2measurement is more convenient than the methods using an alkaline absorbent, in terms of sensitivity and speed. In this paper, an automatic set-up using IRGA and a personal computer for continuous measurement of CO2evolution from multiple samples is described. © 1990 Taylor & Francis Group, LLC.
