GUO Shuo* SONG Zeng-liang WANG Xiao-bing （Hebei Institute of Metrology）

Abstract： Organizer of comparison organizes the implementation of provincial category A comparison： “liquid chromatographs measurement comparison” （project number： 2023-A-02）. The leading laboratory takes primary technical responsibilities for the organization and implementation of the comparison， and the participating laboratory is a total of 9 measurement technical institutions in Hebei province that have obtained the liquid chromatograph metrology standard certificate and obtained the relevant verification and calibration project authorization. The staff of each participating laboratory go to the leading laboratory for on-site handover comparison test， adopting the star comparison route. The leading laboratory compares， analyzes and evaluates the measured values of each participating laboratory. The satisfaction of the verification results is evaluated according to ZΔ value， and the satisfaction of the blind sample test results is determined according to En value method. In this comparison， each participating laboratory completes the comparison work seriously and on time， showing the technical level of each laboratory and achieving the expected purpose. Through this comparison， the participating laboratories comprehensively summarize， find problems， and improve， which is of great significance to ensure the accuracy and reliability of the number of liquid chromatographs used in the province.

Keywords： measurement comparison， liquid chromatographs， leading laboratory， participating laboratory
