Second hand Agilent 7890A-7000B triple quadrupole gas chromatography-mass spectrometer

The second-hand Agilent 7890A-7000B gas chromatography-mass spectrometer is used in conjunction with Agilent 7000B triple quadrupole MS and Agilent 7890A gas chromatography, using a mixture of nitrogen and helium gas to improve ion fragmentation for filtration and quantitative detection. Improved the sensitivity of GCMSMS analysis in many commercial and regulatory applications.

Agilent 7890A-7000B main configuration:

Gas phase section: Column temperature box, chromatography column, split/non split capillary column injection port, electronic gas path control, electronic capture detector (ECD), nitrogen phosphorus detector, high-purity nitrogen gas cylinder+pressure reducing valve, air compressor, high-purity helium gas cylinder+pressure reducing valve, gas chromatography workstation

Mass spectrometry section: Type: Tandem triple quadrupole, ion source: EI source and CI source, analyzer, collision cell, detector, vacuum system, mass spectrometry workstation
