Abstract

A multiple traversal gas absorption cell has been built for the measurement of strong and weak absorption bands in the same sample. By means of external adjustments its path length may be varied from ten centimeters to one meter, ten meters and intermediate values, with transmissions of 80%, 55%, and 32%, respectively. It has a volume of six liters and may be pressurized to 150 psi.
