Description:

The isotope ratio mass spectrometer (IRMS) housed at the Northwest Fisheries Science Center (NWFSC) is used to conduct accurate and precise determinations of isotope ratios of carbon and nitrogen. NWFSC’s Environmental Chemistry Program lab facility includes a Thermo Fisher Scientific’s Flash 2000 Elemental Analyzer coupled with the Conflo IV interface and the Delta V Advantage IRMS. These systems are complex and sensitive and require detailed care and regular maintenance to ensure a high level of performance. This processed report is written to be used in conjunction with hands-on training. It is meant to be treated as a living document and will be updated as changes are made in the procedures. This report provides step-by-step instructions for sample preparation, instrument operation, maintenance of the instruments, sample archival, quality assurance (QA) and quality control (QC) measures and criteria, and data reporting.
