Guidelines for using Open Access LC-MS

  • Attend a training course provided by the mass spectrometry lab manager. (Must be completed before using the instrumentation.)
  • For LC users, reserve the machine 24 hours in advance by emailing lab manager and signing the log book.
  • Filter all samples with a 2 micron particle size filter prior to running.
  • Use volatile solvents and avoid salts and buffers.
  • Log all samples into the log book providing details listed therein.
  • Do not overwrite others saved methods.
  • Transfer data files from the instrument computer within 3 weeks. (Data files will be deleted without notice after 3 weeks.)
  • If no one signs up for APCI, the source will remain ESI.
  • After your analysis is complete, wash off the peak relevant to you several times with an appropriate solvent.
  • If you happen to run out of Nitrogen during a run and change a cylinder, please inform lab manager.
  • If Fused Silica Capillary or Ferrules are found choked or broken, please inform lab manager.
  • Do not share the username and password for the LC MS computer with anyone else.
  • Contact mass spectrometry lab personnel if any other problem is encountered.

Guidelines for using Open Access MALDI-TOF-MS

  • Attend a training course provided by the mass spectrometry lab manager. (Must be completed before using the instrumentation.)
  • Reserve the machine 24 hours in advance by emailing lab manager and signing the log book.
  • Log all samples into the log book providing details listed therein.
  • Zip tip samples.
  • Do not overwrite saved method files.
  • Do not use the MALDI computer to surf the net.
  • Contact mass spectrometry lab personnel if any other problem is encountered.

If you are submitting samples for MALDI-TOF analysis, you are expected to provide the following details:

  • Molecular Weight of protein
  • Source of protein
  • Enzyme used for digestion of protein
  • Any modifications that may have been performed
  • Approximate concentration of sample

IF YOU ARE DONE WITH ANALYSIS AFTER 5 PM, PLEASE TURN OFF THE LIGHTS AND LOCK THE DOOR.
