Calibration and uncertainty assessment for certified reference gas mixtures
Franklin R. Guenther, Antonio M. Possolo
The method to build an analysis function described in ISO 6143, Gas analysis - Comprarison methods for determining and checking the composition of calibration gas mixtures, is extended to recognize the typically small number of instrumental readings obtained for each primary standard gas mixture, and the corresponding uncertainty assessment is obtained by application of the method described in the Supplement 1 to the Guide to the expression of uncertainty in measurement (GUM-S1) instead of the approximations that ISO 6143 suggests.
