Updated with new capabilities in high-resolution accurate mass (HRAM) GC-MS, the Thermo Scientific Orbitrap GC-MS systems now give users in the food safety industry high levels of accuracy in their data.

The new capabilities included on the Q Exactive GC Orbitrap and the Exactive GC Orbitrap, include:

  • Variable electron voltage technology that enables low electron voltage settings to be used during electron ionization protocols, promoting high mass signals and providing high sensitivity for compounds prone to extensive fragmentation.

  • The Orbitrap HRAM Metabolomics Library for electron ionization, metabolite identification is efficiently streamlined. The library includes more than 800 metabolites and the spectra are refined and curated with the elemental composition of each EI fragment verified.
  • New TraceFinder software features a specialized spectral deconvolution library and automated compound identification to enable identification of challenging compounds. With the addition of 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 excellent resolving power, mass accuracy, linear dynamic range and sensitivity of leading Orbitrap technology.
