We currently are operating four stable isotope
ratio mass spectrometers
with associated peripherals. We also have available assorted
instruments and set ups that may help with sample preparation. A
brief summary can also be downloaded as a Word file: ESCSIS-equip.doc. Our
manual is
available as a Word file too: ESCSIS-man.doc--and
now it is also online (wiki format) at: online manual.
Please note, we are mainly set up as a facility--that is people run
their own samples. We have a lot of capabilities.
Unfortunately they are not all "plug-n-play". New procedures and
projects usually take a little time to get up and running smoothly.
For a background on stable isotopes, check out this USGS Resources on
Isotopes site, especially the periodic
table.
