In addition, there are other state-of-the-art analytical instruments at the UMass-Amherst campus, which are available. For example, the campus mass spectrometry facility has a JOEL high resolution GC/MS which has been used by EWRE faculty on many occasions. The UMass NMR Facility has several Bruker NMR instruments, (AMX-II 500, DSX 300, MSL 300 and ASX 300) all of which are available for use by the EWRE program. In addition, there are full-time GC/MS and NMR research scientists who run the two facilities.
