Instrumentation

My laboratory space within the Organic and Biological Mass Spectrometry Group occupies approximately 1,100 square ft in Building 4500S. Additional laboratory space is available in the ORNL Bioenergy Sciences Center (BESC)

Some of the instrumentation fully accessible for my research includes:

Mass Spectrometers

» PE SCIEX API 165 single quadrupole mass spectrometer

» AB/MDS SCIEX QSTAR Pulsar i (QqTOF) mass spectrometer

» AB/MDS SCIEX 4000 triple quadrupole mass spectrometer equipped
   with a beta version of the Flashquant MALDI interface

» AB/MDS SCIEX 4000 Q Trap triple quadrupole linear ion trap

» Finnigan LCQ Deca ion trap mass spectrometers (3)

» Waters TQD triple quadrupole mass spectrometer

» Water Synapt with Acquity UPLC (BESC)

» AB/MDS SCIEX 4000 Q Trap triple quadrupole linear ion trap with
   Acquity UPLC (BESC)

Many of the above instruments are capable of use with multiple ionization source including standard electrospray, nano-electrospray, atmospheric pressure chemical ionization, and atmospheric pressure photoionization

Some of the instruments are used with commercial, prototype, or in house constructed ambient surface sampling and ionization sources including:

MassTech AP/MALDI
Atmospheric Sampling Analysis Probe (ASAP)
Desorption Electrospray Ionization
Liquid Microjunction Surface Sampling Probe.
