Patent ID: 7359804

Claim:
A method of generating calibration curves for implementation in an optical absorption-based multi-gas analyzer (OABMGA), comprising: injecting, into an optical path between an electromagnetic radiation source and a detector, a time-variable puff of gas from a container, wherein the container comprises a mixture of gases at known concentration ratios, and wherein the mixture of gases includes a first gas and other gases; determining a concentration of the first gas in the puff of gas in the optical path based on a measured absorption of electromagnetic radiation, from the electromagnetic radiation source, due to the presence of the first gas in the optical path and a predetermined calibration curve for the first gas; determining a concentration of one or more of the other gases in the optical path based on the determined concentration of the first gas in the optical path and the known concentration ratios for the mixture of gases; and generating calibration curves for one or more of the other gases based on the determined concentrations of the one or more other gases.
