Abstract

Abstract: Uncertainty evaluation model was established for evaluating determination results of HCH and DDT in dried cucumber by gas chromatography. In this paper, the bias and precision of determination method was evaluated. The key factors for measurement results during the analysis process were discussed. Meanwhile, the composed and expanded uncertainties were evaluated. This uncertainty evaluation model was practical, simple and easy to understand and valuable as the reference.

Key words: gas chromatography, dried cucumber, HCH, DDT, uncertainty evaluation
