The GB/T 43663-2024 standard specifies the test method for repeability and conformity of relative strength calibration of static secondary ion mass spectrometry using secondary ion mass spectrometry (SIMS) technology in surface chemical analysis. The standard aims to improve the accuracy and stability of relative strength calibration during SIMS analysis and ensure the repeatability and conformity of test results. By clearly specifying the key parameters and operational requirements in the calibration process, the standard provides a reliable quality control basis for the application of secondary ion mass spectrometry technology in materials science, environment monitoring, surface analysis and other fields. In addition, the standard also emphasizes the specification of instrument calibrating and data processing to help users obtain more consistent and reliable experimental data when performing high-accuracy chemical composition analysis.
