01 Solution Summary
Industrial hydrogen enters a dedicated GC flow path through airtight sampling and quantitative injection via a gas valve, and is separated and determined for battery hydrogen safety detection. Quantification and quality control are arranged as follows: calibration relationships are established around battery hydrogen safety detection using reference materials matched to the detection channel; the qualitative basis, quantification method, and result units are all subject to the applicable method; blanks, calibration verification, duplicate samples, and quality control samples form batch quality control. Each analysis batch also includes a blank, calibration verification, and applicable quality control samples.
02 Standards and Method Basis
Method basis: application method. The laboratory may enter the name and version of the adopted formal method into the project file.
03 Samples and Analytes
