Brief introduction: Rapid Gas chromatographic - Time of Flight Mass Spectrometry technology (Fast Gas Chromatography - Time of Flight Mass Spectrometry, Fast GC - TOFMS) is today one of the most potential GC/ms, and has been widely proved. Compared with the conventional gc, can increase the speed of analysis for 3 ~ 6 times (under the condition of guarantee enough resolution, only ten minutes to the vast number of highly complex mixture medium or medium separation and analysis). Not only greatly improve the work efficiency and save time cost, and low requirement for chromatographic column, significantly reduced the pollution of the instrument, reducing the costs of maintenance and use. Main applications: Petrochemical, flavor spices, tobacco, liquor, food safety, environmental monitoring and necessary analysis instrument in the field of Chinese medicine identification, etc. Technical parameters: 1. Mass number range: 1 ~ 1200 amu 2. The ion source: electron bombardment ion source, double filament design (solvent with automatic protection function and the software automatically switch); Electron emission current biggest 300 ua, 0 ~ 200 ev energy is emitted; Ion source the highest temperature of 300 ° C, the highest temperature of 400 ° C a transmission line 3. Quality resolution: 2000 ~ 3000 (M/z = 502 th) 4. The detection sensitivity: 1 pg/ml OFN, S/N > 500 (RMS); 0.1 pg/ml OFN, S/N > 50 (RMS) 5. Acquisition speed: 200 spectra/s (repulsion pulse frequency 15 KHZ) 6. Acquisition card: ADC (1.5/3 GHZ SPS, with hardware accumulation) 7. The quality of shaft stability: less than 0.01 amu (week) 8. Linear range: 104 9. The vacuum system: twin turbo molecular pump, the former rotary vane mechanical pump (standard, the optional vortex type dry pump); A skin, digital gauge (first grade) and two full range of composite high vacuum gauge
