Since then, the Facility has acquired three further instruments, which make the Facility one of the best-equipped in the area. This system is designed for LC-MS applications, but can also easily be used for analysis of peptides, proteins and other biopolymers. With capabilities of MS n it is also a valuable structural tool. This instrument is equipped for EI, CI, FAB, ESI, and FD ionization methods. This system can be used for separation of complex mixtures by gas chromatography and identification by mass spectrometry.

In addition to the well-equipped mass spectrometry facility, two other shared facilities are available for molecular weight determination. I analytical ultracentrifuge equipped with absorbance and refractive index detectors are available for sedimentation velocity and equilibrium measurements. This system can be used for determine molecular weight, sedimentation coefficients, association constant for intermolecular interactions, and a variety of other parameters. High and low temperature GPC systems equipped with multi-angle light scattering detectors are also available. Gel permeation chromatography enables separations of mixtures and polydisperse samples with determination of the concentration and molecular weight of each species using a combination of refractometer, viscometer and multi-angle light scattering detectors.
