Mass Spectrometry

Services

Mass spectrometry is used to identify substances by molecular weight.   Elemental compositions may be confirmed by accurate mass, and the structure and chemical properties of molecules may be elucidated using tandem MS.  Detection can be accomplished with minute quantities. When coupled with appropriate separation techniques, MS can identify compounds at low concentrations in complex mixtures.  We offer the following analytical capabilities:

• Direct and flow injection.
• Separation method development for LCMS.
• Accurate mass analysis on the TOF (ESI or APCI, positive and negative ion) 
• Tandem MS and quantitation methods development.
• Elucidation of volatile mixtures (GCMS).

Ordering Analyses

Samples should be provided to the mass spec lab (006 Davidson Hall) during business hours.  Pure solid or liquid samples are acceptable; solutions should be dissolved at a nominal concentration of XX, preferably in methanol.  Samples must be completely labeled, and the submission form must be fully executed prior to receiving service.  We generally provides service on a "first come, first serve" basis, but emergencies will get higher priority if possible. 

Services are rendered only after an Interdepartmental Service Request (ISR) has been processed.  Instructions for creating an ISR through HokieMart may be found here.  Commercial customers should contact to make arrangements to submit a purchase order.
