Calibration gas is a combination of gaseous components used as a reference in the calibration of analytical instruments, including gas analysers and gas detectors. These reference gases are a mixture that is generally compressed, existing of one initial gas that is enhanced by one or more components. Calibration gas can contain toxic and flammable gases. calibration gases are used to calibrate and set the gas detectors to ensure they are functioning accurately. The only way to be sure that a gas detector is working correctly is to test it with known calibration gas. Generally, calibration gas is used for the calibration and bump testing of portable gas detectors and fixed gas detection systems. The mixture of gases has been certified to be prepared gravimetrically, using National Institute of Standards and Technology (NIST) traceable weights.
