Abstract
A method and system for identifying and calculating the percentages of gases, such as the automotive and other commercial refrigerant gases, in a gas mixture using infrared spectroscopy is disclosed. The novel system is compact, relatively inexpensive and has greater accuracy than those systems of the prior art.
