Abstract

A simple microcell has been developed for infrared spectroscopy of gases. This cell is based on the light-pipe principle, and employs no curved optical surfaces. A cell with path length of 7.5 cm and internal volume 1.0 cm³ has been constructed, and made to give transmittances of about 50% throughout the 2–15-μ region of the infrared spectrum. Methods for further reduction of sample volume are discussed. This cell should be particularly useful for examination of impurity components from gas chromatography samples.
