| Abstract: | The uncertainty of main technical parameters sensitivity and detection limit of the detector in verification of gas chromatograph were evaluated according to JJF 1059-1999 Evaluation and Expression of Uncertainty in Measurement. The different parts of uncertainty were analyzed. The base mathematical model of measurement was confirmed, and the combined standard uncertainty and the expanded uncertainty of measurement result were calculated. |
