Mass Spectrometry (MS)

Mass spectrometry (MS) is a very sensitive technique which can be used to analyse and characterise compounds to give information about their mass, charge, structure and elemental composition. This information can be used to help identify and quantify the compounds present.

Some of the application areas where mass spectrometry can help include:

  • Organic and inorganic synthesis product confirmation
  • Impurity profiling and identification of unknowns
  • Reaction monitoring
  • Environmental screening
  • Protein Identification


Open access micrOTOF in foreground with the research micrOTOFQ in backgroundThe mass spectrometry facilities in the CCAF at the University of Bath comprise of:

  • Bruker MicrOTOF electrospray time-of-flight mass spectrometer (ESI-TOF) coupled to an Agilent High Performance Liquid Chromatography (HPLC) unit for the separation of mixtures combined with accurate mass measurement. This instrument is available to trained users for Open Access use.
  • Bruker MicrOTOF quadrupole time-of-flight (ESI-QTOF) coupled to a syringe driver within a glove box for air- and moisture-sensitive samples.
  • Bruker MaXis HD ESI-QTOF mass spectrometer for high mass accuracy coupled to a Thermo Scientific Dionex Ultra High Performance Liquid Chromatography (UPLC) unit.
  • Bruker AutoFlex Matrix-Assisted Laser Desorption Ionisation (MALDI) mass spectrometer for polymer and peptide analysis.
  • Agilent NanoLC coupled to an Agilent ESI-QTOF mass spectrometer for proteomics applications.
