GAS ANALYSIS - COMPARISON METHODS FOR DETERMINING AND CHECKING THE COMPOSITION OF CALIBRATION GAS MIXTURES
01-09-2006
12-01-2013
Provides methods for - determining the composition of a calibration gas mixture by comparison with appropriate reference gas mixtures, - calculating the uncertainty of the composition of calibration gas mixtures in relation to the known uncertainty of the composition of the reference gas mixtures with which they are compared, - validating the composition attributed to a calibration gas mixture by comparison with appropriate reference gas mixtures, - comparing the composition of several calibration gas mixtures, e.g. for the purpose of comparing different methods of gas mixture preparation, or for testing consistency among gas mixtures of closely related composition.
