Introduction of Gas Chromatograph Mass Spectrometer Equipment name: Gas Chromatograph Mass Spectrometer(GCMS)
Equipment Type: GCMS-QP2010 Ultra/GCMS-QP2010 SE
Equipment Function: It is mainly used for the volatile and semivolatile components analysis in complex samples ,including the qualitative and quantitative analysis of trace compounds.Moreover, it could be identificated the compound structure.The Gas Chromatograph Mass
Spectrometer (GCMS) can be widely used in food analysis, pesticide residue analysis, chemical, environmental protection ,medical and health fields. Currently,it is used for analysis of pesticide residues in Chinese herbal medicine.
T echnical Parameter:
The GCMS-QP2010 Ultra is our most advanced gas chromatograph mass spectrometer. Descended from the GCMS-QP2010 Plus, it features best-in-class scan speed and sensitivity. A newly designed and patented technology called ASSP (Advanced Scan Speed Protocol) allows this GC-MS to scan at 20,000 u/sec without sensitivity loss or spectral distortion. The result is an instrument that is perfect for “Fast GC” or Comprehensive GC/MS analyses. Productivity and sample throughput can be dramatically increased. Ecology mode saves power and carrier gas consumption allowing for a lower cost of ownership and less environmental stress.
