1. Ion source: dual filament, enclosed ionization chamber, auxiliary small magnet, and lens focused ion optical system. The structure is reasonable, convenient to use, and the filament can be replaced without dismantling the entire ion source. The stability of ion flow can ensure good reproducibility.
2. Quality analyzer: ① High precision machining and assembly of hyperbolic quadrupole pole ② High stability high-voltage high-frequency circuit
3. Ion detector: In terms of ion detection, a high-speed microcurrent receiving system has been developed. This system can not only receive the ion current output by the multiplier intact and undamaged, but also does not increase the background electrical noise after amplification by 107 in the amplification circuit system, greatly improving the signal-to-noise ratio of the instrument and reducing the detection limit of the instrument in practical chemical analysis Greatly reducing the analysis blind spot of GC/MS.
4. Chromatography/Mass Spectrometry Interface Technology: Through extensive experimentation and drawing on advanced foreign experience, a direct insertion GC/MS interface has been developed, which simplifies the structure and reduces the probability of gas leakage; The chromatographic column is easy to accurately locate and install, and easy to operate; At the same time, it can accurately control temperature, with no cold spots, no adsorption, no catalytic decomposition effect, and almost zero sample loss, greatly improving the sensitivity of detection.
5. Vehicle mounted shock absorption system design: This vehicle mounted mass spectrometry analysis system adopts internationally recognized precision shock absorbers for buffering, and by strengthening rigidity and improving the quadrupole structure and key component suspension design, it perfectly solves the seismic problem. The car is equipped with a dedicated workbench with secondary shock absorption design, ensuring the stability and accuracy of mass spectrometry analysis. The car is fully equipped with specialized analytical instruments, as well as dedicated gas sources, power systems, industrial control computers and analysis software, printers, standard gases, and various spare parts to ensure timely start-up upon receiving reports and complaints, and to carry out on-site analysis work, providing first-hand scientific data for mobile on-site work. Special modifications have been made to the body of the car, making the staff inside feel very comfortable, and the internal configuration of instruments and equipment is compact, easy to operate, and within reach. This year, the in car system will undergo seismic performance testing on a series of flat roads to verify the shock absorption effect. The next step is to perform bumpy tests on dirt and mountain roads with extremely poor road conditions to check the performance of the instruments
