Using the LI-7000 to Measure Small Volumes of CO2
In some gas exchange applications, only a small volume of gas (5 ml or less) is available for measurement (as when measuring the respiration of insects or a single fruit, for example). Because this volume is too small to flow through the LI-7000 in a normal fashion, CO2 concentrations must be measured with a different technique. An application note is available that describes this procedure, which involves drawing the small volume of gas into a syringe and injecting it into…
