UMass Environmental Engineering Laboratory Equipment

The Environmental Engineering Program occupies the top two floors of the new ELab II building (completed 2004). This includes about 40,000 ft 2 of research laboratories, graduate student offices and computing laboratories, and 6 walk-in environmental control rooms. Shop facilities available in the College of Engineering include a machine shop, a woodworking shop, a metal and welding shop, and electronics design and fabrication equipment. The University also maintains a well-equipped glass blowing shop. In addition, the Department of Civil and Environmental Engineering has two full-time technicians available to support research efforts.

A wide range of instrumentation is available in the laboratories of the Environmental Engineering Program on campus. Some of this equipment includes:

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 EVE 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 EVE program. In addition, there are full-time GC/MS and NMR research scientists who run the two facilities.
