ICP-MS FACILITY AT UCLA

The UCLA inductively coupled plasma-mass spectrometer (ICP-MS) facility was created when a Shared Instrumentation Grant submitted by the Facility Director to the National Institutes of Environmental Health Sciences (NIEHS) was funded in 2003 for $284,867 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 Dean Linda Rosenstock also was 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 microflow 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 Capillary 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 parts per trillion concentrations for each sample. Chemical and biological speciation is also possible via the chromatographic introduction systems.

 

WHAT CAN BE ANALYZED?

  • ENVIRONMENTAL SAMPLES • Drinking, ground, sea, lake, and river waters • Soils, dusts, and rocks • Dust wipe samples • Aerosol samples • Turbid liquids •   Air samples (midget impinger or solid sorbent) • Hazardous and solid wastes
  • BIOLOGICAL SAMPLES • Blood, plasma, saliva, and urine • Tissues like organs • Plant materials (vegetables/crops) • Hair, skin, nails, teeth
  • FOODS • Liquids like beverages (sodas, wine, beer, supermarket drinking water) • Solids like tea, coffee, fish, meats, market vegetables, food containers
  • RESEARCH & DEVELOPMENT MATERIALS•Semiconductor materials • Nanotechnology solid   substrates • Engineering materials • Metal alloys • Organometallics • Metallic parts

10-100 ppb  Ca, Fe, K, S, Si

>100 ppb  Cl, N, O, Xe

F, He, Ne, Ar, and Kr cannot be analyzed.

Lower limits are achievable if sampling, handling, and processing are done entirely in clean Teflonware/plasticware (NO GLASS!), and in Class 1000 or better clean rooms.

 

WHAT WE CAN DO FOR YOU?

We can:

  • Write the analytical sections of your grant application if you wish to collaborate directly, and do a budget for that section. In that case, support for the ICP-Facility Director will be requested as well as ICP-MS Operator support, as negotiated. In return, lower grant costs will occur because of bulk costs of supplies.
  • Allow graduate students/staff to be trained. ICP-MS Operator time for the training must be supported.
  • Give you advice on how to handle, process, and transport your samples.

You can:

  • Order samples analyzed machine-ready in 5% (v/v) nitric acid or provide them to be digested. Please fill in the order form.
  • Write in ICP-MS operator salary into your grant applications (a minimum of 5%) and get reduced analysis prices according to the proportion of operator support.
