A Controlled-Environment Chamber for Atmospheric Chemistry Studies Using FT-IR Spectroscopy

Abstract

A one-meter diameter, Teflon coated, stainless steel sph ere has been constructed as a tool for conducting studies of the atmospheric chemistry of toxic chemicals. The temperature can be controlled from 5 to 50 deg C. The chamber can be evacuated to 5 X 10 to the minus 6th power torr. Gas samples can be introduced from an external manifold. Solid samples of various kinds can be placed into the interior of the chamber through a 12-in sampling port to determine their effects on gases under study. The chamber is equipped with an in situ, multipass optical system which allows infrared path lengths of 100 meters to be used for the analysis of chemical species. Keywords: Chamber, Controlled environment, Long-path cell, FT-IR, Hydrazine decay, Atmospheric simulation.
