This regulation specifies the calibration methods for organic magnetic mass spectrometers newly installed, in use and after debugging. This procedure specifies the calibration methods for newly installed, in-use and debugged quadrupole mass spectrometers. This procedure applies to newly manufactured and used chromatography-ion trap mass spectrometers (hereinafter referred to as instruments) after neutralization and repair. The main focus of the instrument is chromatography-mass spectrometry.
