UCSC received the Finnigan
MAT Element ICP-MS in January 1995, the first academic
institution in the US to install one. I would guess that
we have run for more hours, analyzed more diverse sample
types, and had more users on the instrument than any other Element
lab.
The magnetic sector mass spectrometer, in addition to providing
high resolution capabilities, has a fairly linear mass response
curve that is much less affected by sample matrix than quadrapole
instruments. This has allowed us to do all sorts of analyses
in low-res (R=300) mode, including Pb isotope ratios and
routine rock and carbonate (coral, foram, etc.) analysis
with better precision and accuracy than we ever expected.
We have conventional sample introduction equipment: concentric
and micro-concentric nebulizers from Glass
Expansion and
ESI;
cooled Scott-type double pass and cyclonic spray chambers
in glass and Teflon; and fixed and demountable torches.
We also have a CETAC AX-100
autosampler, ESI Apex HF, ESI ACM, ESI Spiro, CETAC USN-5000
Ultrasonic nebulizer, and CETAC MCN-6000.

We are in the process of acquiring
funding for a Thermo Element XR, as well as a New Wave
UP193FX Excimer laser ablation system.
