In 2009, a new plasma analytical facility was established to replace our 15 year old Element 1 (the first in an U.S. academic lab). The facility now includes a Thermo Element XR high-resolution ICPMS, an Thermo X-Series II quadrupole ICPMS, a Thermo iCap 7400 ICP-OES, a Photon Machines Analyte 193H excimer laser system, and a Zygo NewView Element XR7200 Vertical Scanning Interferometer for depth profiling and analysis of laser pit morphology.
ICP-SF-MS, ICP-Q-MS, ICP-OES, how do they compare?
Combined with our suite of plasma introduction systems (desolvating nebulizers, flow injection system, Peltier-cooled spray chambers, etc.), we are equipped to measure most of the periodic table, over a wide range of concentrations, in solids and liquids of a wide range of compositions. A diverse user group includes marine chemists, igneous geochemists, cosmochemists, archaeologists, inorganic chemists, geochronologists, environmental toxicologists, and paleo-oceanographers, to name a few.
The Plasma Lab does not support sample preparation or clean lab facilities. However, these capabilities do exist in the UCSC Earth and Marine building. Please see a partial description of these facilities here.
Element XR (eXtended Range) magnetic sector high resolution ICP-MS
Selectable mass-resolution and high sensitivity facilitate the reduction of interferences for for quantification of trace to ultra-trace analyte concentrations.

X-Series II quadrupole ICP-MS
Robust, fast-scanning quadrupole mass spectrometer ideal for quantification of ppb to ppm concentrations in aqueous low- to medium-load matrices or coupled to the laser ablation system for the analysis of solid samples. We have also coupled the quad to additional introduction system for speciation analyses.

Photon Machines (now Teledyne Photon Machines) Analyte 193H excimer Laser Ablation System
For introducing solids as aerosols to an ICP-MS. This is a highly capable laser ablation system combining ultra-short pulse length (<5ns) at 193nm wavelength. Can be coupled to either of the ICP-MS. A HelEx II Active 2-Volume Cell enables fast sample exchange, high stage location and signal reproducibility, and fast washout. The laser was upgraded in 2015.
