Abstract
A system and a method are provided for analyzing a small sample in a test chamber using infrared spectrophotometry. The invention is particularly applicable to analyzing a liquid sample in a test chamber by subjecting the liquid sample to infrared spectrophotometry and analyzing the infrared spectra of the subjected liquid sample. An evaporator is provided to cool the sample to sub-zero temperatures by forcing a refrigerant through the evaporator to cool the sample prior to testing.
