The JMU Mass Spectrometry Teaching & Research Facility, housed within the Department of Chemistry & Biochemistry, was established in 2010 with two Major Research Instrumentation (MRI) grants from the National Science Foundation. Over the years, new instruments have been added so that the facility provides the latest in mass spectrometry capabilities. The instruments housed in the facility include: LC/MS:
All four instruments are equipped with an electrospray source. The time of flight instruments afford the high mass accuracy and high resolution necessary for identification of unknowns in complex mixtures. The MS/MS capability of the q-TOF instruments afford additional structural information. The sensitivity of the QQQ makes this instrument ideal for small molecule quantitation. Together, these four instruments provide a robust platform for the qualitative and quantitative analysis of biological and environmental samples. DART/MS:
This instrument affords direct ionization of samples with little to no sample prep. Compounds may be ionized directly from a solid surface. Compounds in solution are ionized by dipping a glass rod in solution and waving the rod in front of the DART source. This instrument is most often used by synthetic organic chemists to quickly obtain the exact mass of synthetic products. GC/MS:
The instrument affords the routine identification quantitation of volatile compounds. Flavor profiling is often performed on this instrument with solid phase microextraction (SPME). ICP/MS:
This instrument affords the routine identification and quantitation of metals over a wide linear dynamic range. |
