Abstract
A calibration method includes receiving data characterizing a first pressure broadening coefficient, a second pressure broadening coefficient and a third pressure broadening coefficient of the target gas absorption associated with a first background gas, a second background gas and a third background gas, respectively. The method further includes, determining a molar ratio associated with the second background gas and the third background such that an effective pressure broadening coefficient associated with a target gas mixture including the second background gas and the third background gas mixed at the determined molar ratio is within a predetermined threshold of the first broadening coefficient. The target gas mixture further includes a target gas. The method also includes calibrating a gas analyzer using the target gas mixture to replace the calibration of the target in the first background gas. The calibration is based on absorption of electromagnetic radiation by the target gas in the target gas mixture.
