  • Process for avoiding error in measuring or determining the gas consumption of matter
    Patent number: 5929317
    Abstract: A process for avoiding error in determining the gas consumption of a sample located in a closed container. An automatic avoidance of error during the phase of adaptation of the sample to the temperature level in an incubator is achieved by monitoring the container pressure before the beginning of measurement in a test phase, and the measurement values for the measurement of the gas consumption are to be evaluated from the reference time point at which the pressure variation over time in the container lies within a predetermined value range.
