ICP-MS facility in EHS

The UCLA inductively coupled plasma-mass spectrometer (ICP-MS) facility was created when a Shared Instrument Grant submitted by the Facility Director to the National Institutes of Environmental Health Sciences (NIEHS) was funded in 2003 to further the research of NIH and other federal agency research grantees at UCLA, the University of California, and other interested  Universities, companies, and research organizations. Generous support from former Dean Linda Rosenstock was also essential.

The award resulted in the acquisition of:

  • An Agilent 7500c quadrupole ICP-MS with hydrogen/helium octopole collision cell to minimize argon and oxygen isobaric interferences, and equipped with automatic sampler introduction and with concentric and micro flow nebulization. Isotope and isotope dilution techniques are also facilitated.
  • An Agilent 1100 Liquid Chromatograph equipped with autosampler and LC-MS interface (atmospheric ionization/electrosp).
  • An Agilent 6890N Gas Chromatograph equipped with a parallel flame ionization detector and GC-MS interface.
  • An Agilent G1602A Capilary Electrophoresis System equipped with autosampler, variable wavelength ultraviolet-visible detector, and MS interface

Thus liquids can be analyzed via the 2 nebulization modes to obtain elemental content in a multielemental manner at part per trillion concentrations for each sample. Chemical and biological speciation is also possible via the chromatographic introduction system.

What can be analyzed?

I. Environmental Samples

  • Drinking, ground, sea, lake and river waters
  • Soils, dusts, and rocks
