Apparatus for analysis of gases or gas mixtures, in particular of trace gases, by means of infrared spectroscopy

摘要

An IR spectroscopic (esp. trace) gas analyser has a sample chamber in which the IR light path length is increased by multiple reflection. The sample chamber (2) is in the form of an internally reflective hollow sphere which can be pressure-tightly and vacuum-tightly sealed, and into and out of which the IR light is coupled. USE/ADVANTAGE - The appts. is used e.g. for detection of silicon cpds. in hydrazine rocket file. It has an extremely simple and compact design and high gas (mixt.) detection sensitivity.
