This laboratory is the only laboratory that can provide the isotope necessary for these analyses as well as conduct urine sample distillation and analysis for stable oxygen 18 and deuterium. These products are not found in the government supply system and are the only commercially available products found to meet the departmental needs.
Geological Survey (USGS) intends to negotiate a purchase with the University of Alaska Anchorage, Stable Isotope Laboratory (SIL) for plant and animal tissue analysis to determine isotopes 13C and 15N, C% and N% in fish muscle tissue, in whole benthic macroinvertebrates, zooplankton, and algae.
The Cornell Stable Isotope Laboratory has two mass spectrometers and three full-time staff with additional student technicians. They also have specialized equipment for pre-processing, including a combination freezer/mill which speeds up pre-processing time. After a search, there was no lab that was able to meet deadlines for the reporting requirement as well as the cost.
Geological Survey, Reston Stable Isotope Laboratory, based in Reston VA, has a requirement for analytical instrumentation maintenance and repair services.
Geological Survey, Reston Stable Isotope Laboratory, based at Reston, Virginia, has a requirement for one Ion Source with Flange (Part 1191760) for a Thermo Delta V Plus Mass Spectrometer.Quotes shall provide pricing and specifications that conform to the description in Section B.1., Schedule of Supplies.
Geological Survey, Reston Stable Isotope Laboratory, based in Reston VA, has a requirement for analytical instrumentation maintenance and repair services.
The USGS Reston Stable Isotope Laboratory has a requirement for an OEM ConFlo IV Interface for a Thermo Fisher Scientific isotope-ratio mass spectrometer.
