Mass Spectrometers

Two Dimensional Ultra Performance Liquid Chromatography Q Exactive HF Hybrid Orbitrap Mass Spectrometer

student and professor in lab with mass spectrometerThe mass spectrometer is complementary to the center’s existing analytical capability and will be integrated with the existing comprehensive two-dimensional gas chromatography mass spectrometry (GCxGC-MS) platform.

The liquid chromatography part of this instrument dramatically increases the separation power by at least five-fold and will detect low abundance molecules in complex samples.  The mass spectrometer part of this instrument has excellent mass accuracy (< 1 ppm) with high mass resolution (R= 240K). Its MS/MS scan speed is up to 18 Hz, and has the capability of polarity switching within one second.

Matrix-Assisted Laser Desorption Ionization-Time-of-Flight Mass Spectrometer (MALDI-TOF)

MALDI-TOFThe department has acquired a PE Biosystems Voyager DE-Pro instrument for measuring molecular weights and obtaining other structural information.
