EmailThe GCMS-SQ6000 Gas Chromatograph-Mass Spectrometer is a newly introduced universal GC-MS instrument. It incorporates an inert ion source, an all-metal molybdenum pre-quadrupole and main quadrupole, and a high-sensitivity detector. These features enable both qualitative and quantitative detection of complex organic compounds. The system offers high sensitivity, stability, and reliability, making it suitable for a wide range of applications, including food safety, pharmaceutical analysis, biological research, environmental analysis, and petroleum and petrochemical analysis.
Features
Adopt molecular pumps and forepumps to easily achieve a high vacuum environment.
Add pre-quadrupole design, with synchronized voltages of pre-quadrupole and quadrupole, reducing contamination of the quadrupole and optimizing the transition electric field from the ion source to the quadrupole.
Utilize off-axis high-energy dynode to reduce ion stream background noise, achieving a higher dynamic linear range and maximizing detection capability.
The use of high-temperature silanization treatment greatly improves anti-pollution and anti-adsorption capabilities, and the equipped independent filament extends the maintenance cycle.
High-precision sensor monitoring and high-precision proportional valve control ensure good repeatability, with control precision up to 0.001 psi.
Simultaneous installation of up to 8 flow modules, including 24 EPC and 8 MFC;
Simultaneous installation of 4 splitless injection ports;
Simultaneous installation of 4 detectors (such as FID, ECD, FPD, etc.) plus 1 mass spectrometer detector.
