Abstract
An automatic no moving parts portable IR spectrometer for the purpose of analyzing automotive refrigerants comprising an IR source with intermittent output by electronic means not requiring an optical cavity or mechanical chopper, a gas cell which is activated via a one touch bellows to initiate a pressure switch triggering the analysis process, said gas cell followed by a non-imaging optical element which diverts the IR energy to a filter and detector equipped with a readout device to show analysis results.
