Siming Wang

Senior Research Scientist; Director of Mass Spectrometry Facility

Siming Wang runs the Mass Spectrometry Facility at the Georgia State University Department of Chemistry.

The Mass Spectrometry Facility is a research resource to provide modern instrumentations and expertise in the analysis of chemical and biological molecules with state-of-the-art mass spectrometers. The Facility operates six instruments including a Thermo Scientific LTQ- Orbitrap Elite coupled with Thermo Scientific Dionex UltiMate 3000 RSLCnano UPLC, a Waters Micromass  Q-TOF micro (ESI-Q-TOF) with a Waters nanoAcquity UPLC- and an alliance HPLC, a Bruker  Doltonics ultrafleXtreme (MALD TOF-TOF) , a Shimadzu QP5050A GC-EIMS , an ABSciex API 3200 (ESI(APCI)-Triple Quadruple) with an Agilent 1200 HPLC, and an Agilent 1100 series II LC-CE-MSD.

The Facility can usually perform routine MS analysis of small organic molecules as well as large biological molecules such as peptides, proteins, nucleic acids, lipids, oligosaccharides, polymers etc in various matrices.  The Facility also routinely conducts exact mass and elemental composition determination, tandem (MS/MS) experiments as well as GC/MS and LC/MS services for both qualitative and quantitative analysis of analytes in various organic and biological matrices.

Siming also teaches the graduate level Mass Spectrometry course.
