Quantitative analytical measurements are a critical component in achieving accuracy in laboratory and manufacturing applications that include petrochemical processes, natural gas, environmental compliance, and health and safety programs. Where the measurement hardware is not calibrated, there can be no certainty in the measurements conducted. Enter calibration gases. The calibration gas standard establishes a known analyzer response to a certified chemical component concentration. This enables sample responses to be converted to a concentration whose accuracy can be determined. This article offers an in-depth review of how calibration standard gases are manufactured, certified, and properly maintained.
