Sample Analysis by Facility Personnel

Facility personnel routinely analyzes submitted samples (see services listed below). Guidelines and forms for sample submission can be found under “Sample Preparation” and “Sample Submission”. Please note that the facility is not equipped or licensed to handle radioactive and biohazardous samples.

  • MALDI  – TOF MS
  • Direct infusion electrospray MS: Syringe pump used to infuse sample solutions for mass spectrometric analysis.
  • HPLC – ESI/APCI MS: Milli-flow HPLC separation combined with mass spectrometric analysis.

Training on Instrument Use

Training on the use of facility instruments is available. Users who wish to run their own samples can schedule with the facility manager to receive training on JEOl AccuTOF (ESI/APCI), Bruker Autoflex Speed (MALDI) and JEOL MStation (GC-MS). Training involves lectures and hands-on experience with the instruments.
