5973 GCMS
**This system is currently adapted to the Pyrolysis furnace**
Summary
The Agilent 5973 is a nominal mass GCMS instrument based upon quadrupole technology. The instrument provides electron ionization in positive ion mode and has the advantages of sensitivity and a reasonably large detection dynamic range. Agilent ChemStation software is used for data acquisition and data processing. The 2017 NIST library of mass spectra is also included. The system also is equipped with a 100-position autosampler, septumless injection (Jade valve) and fast column change hardware.
The Frontier EGA/PY-3030D multi-shot pyrolyzer attachment is mounted on the back inlet port of the Agilent 5973 GC, Pyrolysis is currently the default configuration for the GCT GCMS, but switching back to normal GCMS will be done upon request. This extremely powerful technique can best be understood by browsing through Understanding the Frontier Multishot Pyrolyzer. We have also developed a functional liquid nitrogen based cryo-focussing apparatus so that optimum chromatographic resolution of components can be maintained during thermal desorption (TD) measurements.
The instrument is located in 1238 Hach Hall. Enquiries should be directed to Dr. Brett Boote.
