No. 422, 4th Floor, Building A, Fuhai Technology Industrial Park, Huafeng Zhigu, Yongfu Road, Qiaotou Community, Fuhai Street, Bao'an District, Shenzhen (A422, Building 1, Hongpai Industrial Park)

Software method:

1.1 ★Integrated control of mass spectrometer and gas chromatograph in Chinese;The synchronous scanning function can obtain both scan and sim data in one injection test, improving analysis efficiency; The alternating scanning function can be performed alternately with scan and sim, expanding the analysis function.

1.2 ★ During operation, a time interval can be set to turn off the filament and electron multiplier to protect themCan avoid solvents or other easily saturated substances that peak at intermediate moments.

1.3 The software can automatically select the characteristic ions of the target compound and group them based on the data obtained from the full scan, and save them to the analysis method without manual input;

1.4 Manual/automatic tuning, data acquisition, quantitative analysis and spectral library retrieval functions, analysis result report output;

1.5 Automatic shutdown;

1.6 Chromatographic flow monitoring; Chromatography gas cut-off, mass spectrometry ion source and transmission line automatic cooling protection, mass spectrometry stops running;

1.7 Real time monitoring of molecular pump speed and current, with abnormal prompts.

1.8 ★ Choose unlimited number of groups for ion mode detection (SIM), with a maximum of 128 ions per group.
