Mass Spectrometry

The facility has five instruments for a wide range of applications, from separation, quantitation and identification of organic compounds to high-resolution mass determination of small and large molecules. A number of sample introduction options, MS ionization sources and MS analyzer types are available to allow analysis of small to large molecules in complex matrices, and for different compound chemistries.


Training and assistance in method development on all instruments is provided. Sample analysis is also available, upon request.

The techniques currently available in our facility are:

1. GC-MS (EI) (quadrupole)

    • for separation, quantitative and qualitative analysis of semi volatile compounds
    • suitable for non polar or less polar organic compounds (DB-5MS column installed)
    • other columns of varying polarity available

2. GC- MS (EI/CI) (quadrupole)

    • for separation, quantitative and qualitative analysis of semi volatile compounds
    • suitable for non polar or less polar organic compounds (ZB-5MS plus column installed)
    • other columns of varying polarity available

3. HPLC-UV/VIS-MS (TOF)

    • ESI and APPI ionization sources
    • accurate mass determination of small and large molecules
    • separation, qualitative and quantitative analysis of compounds in a variety of matrices
    • reverse and normal phase chromatography are possible
    • UV/VIS and MS TOF detection

4. UHPLC-UV/VIS-MS/MS (quadrupole TOF) (training to be announced soon)

    • ESI and APCI ionization sources
    • accurate mass determination of small and large organic molecules
    • separation, qualitative and quantitative analysis of compounds in a variety of matrices
    • UV/VIS and MS qTOF detection

5. CE-UV/VIS

    • separation and quantitative analysis
    • suitable for inorganic anions and cations.

Potential users of the facility are encouraged to meet with the facility manager prior to training to discuss the scope and nature of their work and to determine the most appropriate instrument choice.
