Mass Spectrometry

MS schedule


We have three of these instruments in the lab. One of these instruments have been modified to allow introduction of reagent gases for ion-molecule reactions. Ionization techniques available on these instruments include: electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), nanospray-ESI and atmospheric pressure matrix assisted laser desorption (AP-MALDI). Both instruments are also capable of multiplexed mass spectrometry when parts of the electronics are temporarily by-passed and replaced with other external electronic components.


  • 3 Bruker Daltonics Esquire LC ion trap mass spectrometers
  • 1 Bruker AmaZon quadrupole ion trap mass spectrometer
  • 1 PerkinElmer Nexion Inductively coupled-plasma mass spectrometer with a Cetac laser ablation source
  • 1 Thermofinnigan LCQ classic quadrupole ion trap mass spectrometer
  • 1 Mini 10 portable ion trap mass spectrometer
  • 1 Bruker Autoflex III MALDI-TOF mass spectrometer
  • In addition to these mass spectrometers, we also have full access to all mass spectrometers in the Mass Spectrometry Center on campus including another Esquire-LC, MALDI-TOF, high resolution two-sector mass spectrometer and GC-MS.


  • Micro-Tech Scientific Nano-LC System
    The instrument can be coupled directly with our Esquire-LC for LC/MS and LC/MS/MS experiments
  • Two Agilent HP 1100 and one 1090 HPLC System
    These instruments can be used with a UV-VIS detector as a standalone or can be coupled directly to our Esquire-LC for LC/MS and LC/MS/MS experiments
