GC-MS3110 vehicle-mounted gas chromatography (quadrupole) mass spectrometer Introduction
Mass spectrometer and its combined technology are one of the widely used and well-developed scientific instruments in scientific instruments today. Its application fields cover atomic energy, life sciences, clinical and pharmaceutical sciences, chemistry, environmental monitoring, food safety, inspection and quarantine, forensics, criminal investigation science, chemical industry, petrochemical industry, electronics and geological light. Since the prototype of the mass spectrometer has been formed, six scientists who have been engaged in mass spectrometry research have won the Nobel Prize six times. This also shows the status of mass spectrometry technology in the development of science and technology today.
This product aims to promote the miniaturization, specialization and localization of the color-mass spectrometer, especially the professional application in the fields of inspection and quarantine, food safety, energy, agriculture, etc., forming a wide range of countries, scientific research units, enterprises and users A win-win situation. Features
(1) Ion source: double filament, closed ionization box, auxiliary small magnet and lens focusing ion optical system. The structure is reasonable and easy to use. The filament can be replaced without disassembling the entire ion source. The stability of the ion current can maintain good reproducibility.
(2) Quality analyzer: ①High-precision processing and assembly of hyperboloid quadrupole ②High stability high-voltage high-frequency line
(3). Ion detector: In the aspect of ion detection, a high-speed micro-current receiving system has been developed. This system can not only fully accept the ion current output by the multiplier, but also does not make the main circuit after the amplifier circuit is amplified by 107. The electrical noise increases, which improves the signal-to-noise ratio of the instrument, reduces the detection limit of the instrument in actual chemical analysis, and reduces the GC / MS analysis dead zone.
(4) Chromatography / mass spectrometry interface technology: through a large number of experiments and drawing on advanced foreign experience, the research and development of the direct plug-in GC / MS interface has simplified the structure and reduced the probability of gas leakage; the chromatography column is easy to accurately locate and install, Easy to operate; at the same time, the temperature can be accurately controlled, there is no cold spot, no adsorption, no catalytic decomposition effect, small sample loss, and improved detection sensitivity.
(5). Vehicle-mounted shock absorber system design: This set of vehicle-mounted mass spectrometry analysis system uses precision shock absorbers for buffering, and through the strengthening of rigidity, as well as the improved quadrupole structure and suspension design of key components, the problem of earthquake resistance is better solved. The vehicle is equipped with a two-stage shock absorption design workbench, which ensures the stability and accuracy of the mass spectrometer analysis. The equipment in the car is fully equipped. In addition to the dedicated analytical instruments, it is also equipped with a dedicated gas source, a dedicated power supply system, an industrial control computer and analysis software, a printer, standard gas, and various spare parts to ensure that it is started in time when notified. , Went to the scene to start the analysis work, and provided first-hand scientific data for the mobile field work. The car body has been specially modified to make the staff in the car feel very comfortable, and the internal configuration of instruments and equipment is compact, easy to operate, and within reach. This year, the vehicle-mounted system will conduct seismic performance tests on a series of flat roads to check the shock absorption effect. The next step is to perform bumps on dirt roads and mountain roads with extremely poor road conditions to check the performance of the instrument.
