| Abstract: | By analyzing the source of uncertainty among the determinate hexachlorobenzene content in pyrotechnic composition procedure, a calculation formula for the uncertainty in assay with GC was established. Each variable parameter included stand solution preparation, repetition measurement and sample treatment process etc among the procedure was analyzed. Results showed that uncertainty in the test was 0.176mg/kg. |
