GB/T 26792-2011 Specifies High Performance Liquid Chromatograph. It specifies the classification and structural composition of the instrument, specifies key performance indicators such as infusion pump Flow rate accuracy and Detector Sensitivity, and puts forward strict requirements on the Stability and Repeatability of the instrument. At the same time, it formulates the inspection and test methods of the instrument, as well as the product marking, Encasement, transportation and storage rules. This standard provides a unified basis for the production, mass testing, market circulation and use of High Performance Liquid Chromatograph, guarantees the reliable performance of the instrument, and helps various fields to achieve accurate chemical analysis with its help.
