Ultra fast GC-MS leads to unprecedented peaks in sensitivity and analytical efficiency

With the increasing monitoring of trace compounds related to environmental pollution and human health, there is growing attention to the research and development of high-performance new materials and chemicals, and analytical instruments play a significant role. The all-new single quadrupole gas chromatography-mass spectrometer GCMS-QP2020, with outstanding performance advantages, intelligent analysis software, specialized databases, and multiple analysis systems, comprehensively expands your experimental capabilities and is suitable for demanding analysis needs in various fields.

New large capacity turbo molecular pump

By equipping with a new ultra efficient large capacity turbo molecular pump, the instrument performance of helium, hydrogen, and nitrogen as carrier gases is further improved. The differential vacuum system using an ion source and a quadrupole mass analyzer for exhaust can ensure optimal mass spectrometry under any carrier gas conditions.

High performance ion source

The patented high brightness ion source can obtain analysis results with high sensitivity and stability. No need to replace the ion source, easily switch between ionization modes. The new "Quick CI" function can quickly obtain molecular ions of compounds using CI mode, further enhancing the accuracy of qualitative information. Utilize the limits of mass spectrometry analysis in both quantitative and qualitative aspects.

The patented shielding plate technology can effectively isolate the radiation heat and potential voltage generated by the filament, avoid the generation of active sites in the ion source, and provide a highly stable ionization space.

Usually, it is difficult to obtain molecular ions of compounds using EI ionization method. Quick CI function can be used to quickly switch to CI ionization method for data acquisition and obtain relevant information.

High performance gas chromatograph

High precision electronic flow control (AFC) using room temperature compensation technology ensures long-term stable retention time. In addition, in the constant linear velocity control mode, even if the temperature of the column temperature box changes, the linear velocity of the carrier gas can remain constant, achieving optimal GC separation conditions.

Advanced Scanning Speed Protocol (ASSP) for high-speed scanning control technology ™）

Automatically optimizing the bias voltage of the quadrupole during high-speed data acquisition effectively suppresses the decrease in sensitivity during scanning above 10000u/sec. Compared with traditional instruments, the sensitivity is increased by more than 5 times. Especially in Fast GC/MS analysis, FASST analysis for synchronous data acquisition of Scan and SIM, and the application of GC × GC-MS, the sensitivity of scan data and the accuracy of mass spectrometry are significantly improved.

Changes in chromatogram intensity at different scanning speeds
At scanning speeds above 10000u/sec, the ASSP function is utilized to accelerate ions at the optimal voltage while maintaining ion signal strength, suppressing signal strength degradation across the entire mass range.
