Mass Spectrometry Facility

The Mass Spectrometry Facility in the Chemistry Department at the University of the Pacific in Stockton, CA, USA, has the following state-of-the-art mass spectrometers:

Varian Triple-Quadrupole ESI-MS

Varian Triple-Quadrupole ESI-Mass Spectrometer

JEOL DART AccuTOF (Direct Analysis in Real Time)


JEOL LCmate



JEOL GCmate



VARIAN 1200LC



VARIAN GC-MS 2000



VARIAN GC-MS 4000



KRATOS/SHIMADZU AXIMA-CFR MALDI-TOF



SIEMENS Quantra FT-ICR


TOMTECH Quadra 120 (spotting robot)


The Pacific MS Facility supports research activities in the Departments of Chemistry and Biology in the College of the Pacific and in the University's School of Pharmacy and Health Sciences as well as outside collaborations with researchers in other academic institutions and industry.

The Chemistry Department at Pacific is also the home to the week-long Annual Workshop on Chromatography and Mass Spectrometry.

This course, now in its 17th year, provides training to those outside of the university life interested in increasing the knowledge in mass spectrometry through the use of state-of-the-art instrumentation provided specifically for the course through major manufacturers of mass spectrometers.

Scientists from all over the world working mostly in industry, but also from academia and government agencies, gather each year to take advantage of this continually evolving course.

The course also provides a valuable training ground for Pacific's chemistry and pharmacy graduate students who finish their studies having completed several years of being teaching assistants for this dynamic course.
