Auditigas

Auditigas refers to a type of gas that is used to calibrate or test the accuracy of gas detection equipment. This specialized gas is prepared to a precise concentration of a target analyte, often mixed with a balance gas such as nitrogen or air. The purpose of audit gas is to ensure that gas sensors are functioning correctly and providing accurate readings, which is crucial for safety and environmental monitoring.

Calibration involves exposing the gas detection instrument to the audit gas. The instrument's response is then compared to the known concentration of the audit gas. If the instrument's reading deviates significantly from the certified concentration, adjustments are made to recalibrate the sensor. This process verifies the instrument's sensitivity and accuracy.

Audit gases are used in various industries, including oil and gas, chemical manufacturing, mining, and wastewater treatment, where the presence of hazardous gases needs to be continuously monitored. They are also employed in laboratories and by environmental agencies for regulatory compliance and research purposes. The composition and concentration of audit gases are typically certified by accredited laboratories to ensure their reliability. Proper handling and storage of audit gas cylinders are essential to maintain their integrity and prevent contamination.
