Features and functions:

1. GC as the injection system, the sample to be measured will be separated and directly into the mass spectrometry for detection, that is, to meet the requirements of mass spectrometry analysis of the sample singularity, but also to eliminate the cumbersome process of sample preparation, transfer, not only to avoid sample contamination, the mass spectrometry injection volume can also be effectively controlled, but also to reduce the pollution of the mass spectrometer, greatly improving the separation of the mixture, qualitative and quantitative efficiency.

2. High qualitative capability. As a detector, mass spectrometry detects the ion mass and obtains the compound mass spectra, which solves the limitation of gas chromatograph characterization. Since the mass spectra of different compounds are not the same, mass spectrometry is a general-purpose detector and a selective detector.

3. The chromatographic peaks that have not yet been separated can be separated. With extracted ions, selected ion monitoring or selected reaction monitoring methods, as well as in combination with certain data processing methods, the peaks on the total ion flow chromatogram that have not been separated or masked by chemical noise can be separated.

Attachments and Configurations:Gas autosampling valve, inlet, ES ion source, mass analyzer, detector, vacuum system.
