This article presents a novel metrological calibration method for trace chromium(VI) analyzer. The study identifies all factors that affect the accuracy of chromium(VI) analyzers, and proposes calibration items and method for the analyzer based on its working principle. The calibration items include pump set flow error and pump flow stability, set temperature error and temperature control stability of column oven, baseline noise and drift, minimum detection concentration, linear range, and qualitative and quantitative repeatability. Experimental results shows that, the presented method can meet the requirements for the metrological performance evaluation of chromium(VI) analyzer. The calibration method is scientific and feasible.
