Chemical Instrumentation at Westmont College

The Westmont Chemistry Department possesses a wide range of top-quality, modern chemical instrumentation.  Students have access to these in their lab courses and in their research projects with the faculty. Here is a list of some of our holdings with photos taken in our labs.

Bruker Avance 400 MHz NMR Spectrometer

The Bruker Avance III 400 MHz NMR spectrometer (acquired in 2012) includes a Prodigy Cryoprobe.  It can perform 1D and 2D NMR experiments on a variety of nuclei including 1H, 13C, 31P, 19F, and 14N.

UV-VIS Spectroscopy:

The department possesses two Thermo Evo300 scanning UV-vis spectrophotometers that can be used to measure the electronic spectra of inorganic and organic compounds, to follow the kinetics of chemical reactions, and for quantitative chemical analysis.


Emission Spectroscopy

The Thermo Electron AB2 fluorometer used for characterizing the emission spectra of compounds and for chemical analysis.


Infrared (IR) Spectroscopy:

The department has two FTIR spectrometers; a Nicolet iS10 and a Nicolet Nexus 470.  The  iS10 is equipped with a Nicolet Smart Performer SR-ATR attachment, enabling easy measurement of the spectra of solids and liquids.


The Nexus 470 can also be used in conjunction with the attached Nicolet Centarius Infrared microscope.


Atomic Absorption Spectroscopy

The Perkin Elmer Atomic Absorption Spectrometer is used to do trace metal analysis.



The Rudolph Autopol polarimeter can be used to measure the ability of chiral compounds to rotate plane polarized light.  It is especially useful for following reactions that result in enantioselective generation of a chiral product.


Mass Spectrometry:

The department possesses two mass spectrometers.  One is an Agilent quadrupole mass spectrometer with electron impact ionization as part of its GC/MS instrumentation (see chromatography below). There is also a ThermoFinnegan LCQ Deca Ion Trap mass spectrometer with an electrospray probe.  This is used for many applications including studying synthetic proteins. This can be attached to our HPLC to obtain an LC/MS.

X-ray crystallography:

Single-crystal X-ray data can be collected at California State University - Channel Islands, or at the University of California, Santa Barbara.

High-Performance Liquid Chromatography (HPLC):

An Agilent 1100 HPLC with a refractive index and diode array UV-vis detector can be used for analytical and small scale preparative separations.


Protein Purifier:

The Department has a GE AKTA Protein Fast purifier with UV detector and fraction collector.


Gas Chromatography (GC) and GC-MS:
The department has an Agilent 6890 GC equipped with a 5973N mass-selective detecto r.  This instrument is also capable of recording electron impact mass spectra.  Routine work can be readily performed using our Agilent 6890N or Hewlett Packard 5890 gas chromatographs equipped with thermal conductivity and flame ionization detectors.
