Department of Chemistry Instrumentaion Facility (DCIF) Mass Spectrometer Instrumentation
The Department of Chemistry Instrumentation Facility is the shared instrument facility for the Chemistry Department located in the sub-basement of the Camille Edouard Dreyfus Building on the main MIT campus. The facility's function is to maintain a sufficient number and type of state-of-the-art major analytical instruments in order to support the ongoing research programs within the MIT Chemistry Department. Currently, there are four permanent staff members who provide instrument training, maintenance, repair and applications assistance to well over 300 users. The lab currently houses six NMR spectrometers, one EPR spectrometer,one Mössbauer spectrometer, one high resolution fourier transform mass spectrometer, a GC-MS, a polarimeter, a CD spectrophotometer, and a FT-IR spectrometer.

Mass Spectrometer Instrumentation -- The Facility houses a newly acquired Bruker Daltonics APEXII 3 Tesla Fourier Transform Mass Spectrometer (or an Ion Cyclotron Resonance Mass Spectrometer for the purists out there), controlled by a Silicon Graphics O2 workstation. Ionization sources include electrospray (ESI), electron impact (EI), and matrix assisted laser desorption (MALDI). The spectrometer is equipped with a Gilson 215 liquid handler (auto sampler) to assist in high throughput low-resolution ESI analysis. The spectrometer is run exclusively by Li Li our mass spectrometry research specialist.
