| Abstract: | This paper briefly introduces the determination method of omethoate residue in vegetables by gas chromatography.According to JJF1059-1999 evaluation and expression of uncertainty in measurement, the sources of standard uncertainty are analyzed in detail. The combined standard uncertainty and expanded uncertainty are calculated by selected suitable evaluation methods. The aim of reasonable evaluation of uncertainty of measurement is to evaluate the ability of technique and instrument of laboratory. |
