The most common form of GC/MS is known as electron impact (EI) GC/MS. This analysis is performed by separating organic compounds via a gas chromatograph then detecting them by bombarding the compounds with high energy electronics. The bombardment results in a unique fragmenting pattern that can be used as a fingerprint to confirm the compounds presence. Extracting the most prominent fragment (or ion charge separated by mass/charge) and measuring its response allows the laboratory to arrive at a concentration of the compound.
Analytical Instrument Resource buys and sells GC-Mass Spectrometers from a variety of manufactures such as Agilent Technologies or Hewlett Packard, and Thermo Scientific. In addition to GC/MS systems, we provide parts and components such as thermal switches, diffusion pumps, vacuum gauges, two stage pumps, electronics and more.
Our analytical systems are expertly refurbished, tested and most include a full six month warranty. Test data is provided with each GC/MSD System. Training and Professional Installation options are available.
