Formaldehyde content in foods was measured by high performance liquid chromatography/HPLC method. By analyzing the source of uncertainty, a calculation formula for the uncertainty in assay with HPLC 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 0.50mg/kg.
