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:

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 17^th 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.

New Infrared Spectrometer Meets Advanced Analytical Challenges

 

         PerkinElmer (USA), have announced the launch of the FrontierTM Infrared Spectrometer, a high performance infrared (FT-IR) spectrometer.
Part of a new family of spectrometers, the Frontier analytical platform meets diverse FT-IR challenges ranging from everyday measurements to the most advanced, complex analyses. The instrument combines sensitivity with flexibility for many diverse sectors, from polymers and chemicals to consumer goods and pharmaceuticals, helping to protect consumers and the environment across the world.
Frontier’s superb sensitivity and configurability ensure superior performance in demanding applications,           

              helping to advance safe drug development, understand complex chemical and material properties, and meet the challenging requirements of research and academia. Dusty Tenney, president, Analytical Sciences and Laboratory Services, Perkin Elmer, commented, “With more than 65 years of experience in spectroscopy, Perkin Elmer has now developed a specialized infrared spectroscopy platform that can be adapted for customers’ research requirements. With Frontier, multiple analysis can be conducted using a single instrument. From near- to far-infrared analysis, Frontier is our most powerful spectrometer to date.”

             A range of patented PerkinElmer technologies enable the Frontier to produce superior infrared spectra. Atmospheric Vapor Compensation™ (AVC) features an advanced digital filtering algorithm designed to eliminate CO2 and H2O interferences for accurate FT-IR results. The fifth generation Dynascan™ fixed mirror-pair interferometer requires no dynamic alignment to compensate for errors in linear mirror movement. PerkinElmer’s AVI Standardisation™ calibrates spectrometer wavelength scales to a higher accuracy than achieved with conventional calibration methods.

New Protein Microscope

               The atmospheric pressure imaging mass spectrometer part of a protein microscope that was recently developed by a team of scientists at The George Washington University's Institute for Proteomics Technology and Applications, is seen during a media tour October 19, 2006 in Washington, DC. The protein microscope combines a mass spectrometer with laser sampling through a sharpened optical fiber to produce images and molecular analysis of living samples at a resolution of 100 nanometers, which is 30 times more powerful than optical microscopes. Scientists of the team claim the protein microscope has a potential to advance the treatment of a wide range of diseases, including neuromuscular ailments such as Lou Gehrig's disease, as well as HIV and cancer.
