Introduction: The SHP8400PMS-L online mass spectrometer injection system has a single-channel real-time split injection (1.6 seconds set of data) and 16-channel injection; the ion source uses a classic electron bombardment ion source (EI) with dual filaments, one Work, one backup, automatic switching and calibration, reducing downtime maintenance; the quality analyzer is equipped with a mature, fast scanning quadrupole mass analyzer to meet the separation requirements of complex components; for different test component concentrations, we Both Faraday detectors (ppm level) and electron multiplier detectors (ppb level) are available, and the entire instrument performance and data processing system can meet different customer needs. Features: 1. The analysis speed is fast, the sensitivity is high, the stability is good, and the analysis accuracy is the main consideration for selecting the online mass spectrometer. The SHP8400PMS-L has superior performance in these four aspects: 2. Analysis speed - fast analysis of a set of data for 1.6s; analysis of components is not limited, analysis time can be set according to the requirements of the analysis process; 3. Sensitivity - Faraday detector: 100% ~ 10ppm; electron multiplier detector: 100% ~ 10ppb; 4. Stability - the instrument continuously runs RSD ≤ 0.5% for 30 days, based on 1% Ar in air; 5. Analysis accuracy - RSD ≤ 0.25%, based on 1% Ar in air; In addition to the superior performance of the above four aspects, SHP8400PMS-L also provides a 16-channel sampling system to meet the needs of simultaneous analysis of multiple reactors: 6. Each channel is independent intake and independent exhaust, completely eliminating inter-channel interference 7. Continuous flow sampling to ensure real-time gas update 8. Controllable air inlet line to effectively prevent process gas from condensing during sampling 9. Software set online cleaning program to ensure analysis accuracy Technical Parameters: Quality range: 1-100, 200, 300 amu Injection system: Single channel, multi-channel high-precision quantitative sample introduction system Mass Analyzer: Quadrupole Ion source: electron bombarding ion source Detector: Faraday cage / electron multiplier Detection limit: 10ppm (Faraday cage), 10ppb (electron multiplier) Mass shaft stability: <±0.1amu/72h Vacuum system: oil-free diaphragm pump and turbomolecular pump Data output: Ion flow intensity data output and online calculation of percentage concentration Number of components tested: unlimited
