Thermo Scientific Orbitrap GC-MS systems

Updated with capabilities in high-resolution accurate mass (HRAM) GC-MS, the Thermo Scientific Orbitrap GC-MS systems are suitable for metabolomics, food safety, environmental, pharma and toxicology applications. The systems are designed to provide sensitive and selective compound identification of complex samples for both research and routine laboratories performing gas chromatography mass spectrometry (GC-MS).

The addition of Variable electron Voltage (VeV) technology enables low electron voltage settings to be used during electron ionisation (EI) protocols, promoting high mass signals and providing high sensitivity for compounds prone to extensive fragmentation.

Due to the Orbitrap GC-MS HRAM Metabolomics Library for electron ionisation (EI), metabolite identification is efficiently streamlined. The library includes more than 800 metabolites and the spectra is refined and curated with the elemental composition of each EI fragment verified.

TraceFinder Automated Compound Identification software features a specialised spectral deconvolution library and automated compound identification to enable identification of challenging compounds. With the addition of the Kovats retention index to the scoring index of unknowns, user confidence in compound identification is improved, especially in relation to isomeric compounds.

The Q Exactive GC Orbitrap is a relatively easy-to-use GC-MS system that provides high-quality data for compound discovery, identification and quantitation for comprehensive analyses. The Exactive GC Orbitrap GC delivers sensitive, routine-grade performance in both targeted and non-targeted screening protocols. Both systems provide good resolving power, mass accuracy, linear dynamic range and sensitivity.
