| We
are currently operating five stable isotope
ratio mass spectrometers and their associated peripherals. In
addition, we have an assortment of tools and accessories to help with
sample preparation. A brief summary can be downloaded in Word format: ESCSIS-equip.doc. Our manual is available as a Word file, too: ESCSIS-man.doc In addition, it is also online in Wiki format: 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. |
