Abstract:

Based on the basic method and procedure for assessment of uncertainty, a mathematical model was established to assess the uncertainty of HPLC analysis of oxolinic acid residue in chicken. Factors contributing to the uncertainty were investigated by termwise analyzing and synthesizing the sources. The oxolinic acid residue in test portion of chicken was 78.0 μg/kg, and the expanded uncertainty was calculated as being 3.5μg/kg.

Key words: uncertainty, HPLC, oxolinic acid, assessment
