The comparison method based on multi-point calibration is applicable to all calibration gas mixtures. However, due to the time-consuming, material-consuming and cumbersome operation of multi-point calibration, in many cases, single-point and two-point calibration are used to determine the value of the gas. The comparison method is used as an alternative method and has been widely used in industrial gases and related fields. Comparison of single-point and two-point calibration methods can usually provide a balance between the cost, effort and accuracy of determining the content of mixed gas components. A reasonable balance is achieved; however, one-point and two-point calibrations need to be validated to ensure proper use. This document provides the applicable conditions, limitations, evaluation of measurement uncertainty, and calculation methods for the comparison method based on single-point and two-point calibration. and ways of expression.
