Mass Spectrometry

We provide a Mass Spectrometry Service to the School of Chemistry and other Departments within the University as well as External Organizations.  An overview of the service we offer, current instrumentation and contact details is given below.  Please note we are not UKAS accredited.

 

Service

The Mass Spectrometry Service utilises Jeol M-STATION and Bruker microTOFq Mass Spectrometers to produce quality Low and High Resolution spectra using Electron Ionisation (EI), Chemical Ionisation (CI) and Electrospray (ESI) techniques.

The service also incorporates Shimadzu Gas Chromatography Mass Spectrometry (GCMS) and Shimadzu Liquid Chromatography Mass Spectrometry (LCMS) instruments facilitating trace organics analysis of volatile, semi-volatile and non-volatile mixtures.

 

Instrumentation and Scope of Analysis

Jeol MSTATION JMS-700 High Resolution Mass Spectrometer

This is a magnet sector mass spectrometer with a combined source to enable Electron Ionisation (EI) (analysis of volatile and semi-volatile molecules) and Chemical Ionisation (CI) (analysis of molecules requiring a softer ionization than EI), normally in the mass range 50Da to 800Da.  The mass range can be extended if required.  This instrument is capable of carrying out mass measurements accurate to <5ppm.

Bruker microTOFq High Resolution Mass Spectrometer

This instrument has an Electrospray (ESI) ion source coupled to a time-of-flight (ToF) analyser.  Analysis can be performed in positive and negative ionisation modes facilitating the analysis of a wide range of organic compounds with medium to high polarity, normally in the mass range 100Da to 2500Da.  This instrument is capable of carrying out mass measurements accurate to <5ppm.

Shimadzu Liquid Chromatograph Mass Spectrometer LCMS – 2010EV

This Shimadzu LCMS is a single quadrupole mass spectrometer system which can operate in positive and negative ion modes and has an upper mass limit of 2000Da.  The LC system includes a dual wavelength UV-Vis detector.  This instrument can be used to analyse  medium to high polarity organic molecules, including drug metabolites and peptides.

‌Shimadzu Gas Chromatograph Mass Spectrometer GCMS-QP2010S

This Shimadzu GCMS is a single quadrupole mass spectrometer system with an upper mass limit of 900Da.  The instrument can operate in both EI and CI modes and can be used to identify and quantify organic components of volatile and semi-volatile mixtures.
