Comprehensive 2-Dimensional GCxGCMS System
Fast, Sensitive Separation of Complex Mixtures
Comprehensive GC-MS (GCxGC-MS) is a powerful chromatographic technique that provides separations of complex mixtures that are not possible by conventional Gas Chromatography.
Shimadzu's Comprehensive GC-MS (GCxGC-MS) System is comprised of a combination of our fast scanning, high-sensitivity quad GCMS-QP2010Ultra and the Zoex Corporation series of modulators, ZX-1 or ZX-2. The QP2010Ultra is the only quadrupole mass spectrometer on the market that scans fast enough to fully characterize the 100msec to 600msec peaks created by the modulation process. More economically priced than a TOF-MS, the quadrupole-MS has the added capability of Chemical Ionization and Negative Chemical Ionization for molecular ion spectral analysis and electrophyllic compound selectivity. The spectra generated by quad-MS are easily matched by the standard commercially available libraries such as the NIST, Wiley and FFNSC.
This system is available in a variety of configurations for complete control of your analysis. A second, full function, GC oven, with heated transfer line, can be added to the GCMS system that will allow separate temperature control of the first and second dimensional columns. It is also possible to incorporate our line of Advanced Capillary Flow products such as detector splitting packages, deans switching and backflush kits.
What is GCxGC?
The chromatogram obtained through repeated trapping and injection is rendered in two dimensions using specialized software, with the first and second dimensions on respective axes.
