SUMMARY: The report reviews methods of continuous infrared absorption analysis and gives the description and performance of a commercial infrared CO 2 analyser. Examples are given of the use of an infrared analyser recorder to measure CO 2 in effluent air from deep cultures. This measure of metabolic activity can be used to estimate growth rate. It is particularly useful because results are obtained with little or no measurement lag and without the need to sample the culture fluid itself.
