Gas chromatography-mass spectrometer

GCMS-18883Gas chromatography-mass spectrometerA single quadrupole mass spectrometer developed by Sunny Hengping Instrument for the environmental testing market, with good long-term stability and economic applicability. This product is incubated and produced by the research unit of Shunyu Hengping Instrument and the Shanghai Mass Spectrometry Instrument Engineering Technology Research Center.

Technical advantages:

GCMS-18883The quadrupole used in gas chromatography-mass spectrometry is a specially designed long rod structure for high-performance analysis, with excellent resolution and mass axis stability, providing maximum ion transport efficiency. We adopt the latest processing technology achievements from the national major scientific instrument and equipment development special research, combined with global optimized processing optimization, to ensure the accuracy of each set of four level rods.

The homologous standard requirements for the optimal processing of quadrupole and vacuum chamber ensure the consistency and stability of quadrupole mass spectrometry.

The innovatively designed curved repulsion electrode has better electric field distribution and smoothness compared to the flat repulsion electrode, improving ion generation efficiency and migration efficiency, and achieving better sensitivity and stability.

The integrated EPC module ensures precise and stable control of flow and pressure, and digitally controls the gas path parameters of the separation system, ensuring consistency and reproducibility of analysis results
