A calibration gas is a mixture of gaseous components used as a comparative reference in the calibration of analytical instruments, such as gas analyzers or gas detectors. Calibration is important for all testing instruments and the calibration gas is a means of establishing a known response to a certified chemical component concentration. This paper looks at the key aspects to be aware of when procuring and using calibration gas. We will examine common terminology including metrological hierarchy, traceability, accreditation and units.
