The Power of High Resolution Accurate Mass Using Orbitrap Based GC-MS

Scientific Advocate II
Scientific Advocate II
The Thermo ScientificTM Q ExactiveTM GC hybrid quadrupole-Orbitrap mass spectrometer is a benchtop instrument, designed to bring the power of Orbitrap high-resolution, accurate-mass (HR/AM) to gas chromatographic (GC) separations.
Obtaining mass spectrometer (MS) measurements with high mass accuracy is essential to providing the required selectivity in complex matrices and to increasing the confidence in compound identification and confirmation. For the former, obtaining a consistently high mass accuracy allows the use of very narrow mass extraction windows, taking full advantage of
the instrument’s mass resolving power. For the latter, measuring the mass of a chemical with sufficient accuracy allows the chemist to predict the elemental composition and isotopic ratios to help identify the chemical structure of the substance.
