Simple uncertainty evaluation model for determination of HCH and DDT residues in meat by GC

Simple uncertainty evaluation model was established for suitably,efficiently and rapidly evaluating related measurement uncertainties according to measurement uncertainty evaluations,components for uncertainties plus their relationships of HCH and DDT residues in meat analyzed by gas chromatography(GC).Measurement uncertainties of HCH and DDT residues in meat were evaluated,key procedures of which were listed,and important components were chosen from those factors affecting measurement results for composed and expanded uncertainty calculations.Those results show this uncertainty evaluation model is simple,easy to understand,effective and valuable as reference.
