Mass Spectrometers

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

The 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)

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