Mass spectrometry (MS) is an extremely sensitive analytical method used to measure the mass-to-charge ratios of ions. This data can provide valuable insights into the chemistry of analytes with concentration data ranging down to the nanomolar (10−6 mol/m3) range and, increasingly, as low as the attomolar (10−15 mol/m3) scale. Initially limited to the analysis of positive (+ve) ions using hard ionization techniques (i.e. electron beam ionization), a plethora of mass analyzers now exist for measuring negative (-ve) ions and even free radical species.

RQM+ Lab Services employs a broad range of mass spectrometry methods to obtain the most precise mass spectral data from any type of analyte (gases, liquids, solids, etc.). As part of our comprehensive laboratory testing services, we can prescribe the right mass spectrometric technique for your sample type.

We can identify and quantify unknown species in analytical chromatography using Quadrupole Time of Flight Liquid Chromatography Mass Spectrometry (QTOF-LCMS). If you need to understand the molar concentration of your sample in its native state, we may employ Desorption Mass Spectrometry (DMS). Our expertise in the field is extensive. Simply explore the tabs at the bottom of this page for more information on the mass spectrometry methods that our chemists specialize in.
