Expanding EMSL's isotope analysis capability to additional environmentally relevant sample types
EMSL Project ID
50707
Abstract
We seek to modify instrument peripheral devices and develop needed methods to expand the suite of analytes that can be analyzed using the EMSL isotope ratio mass spectrometry (IRMS) capability. Specifically, this concept contains three separate thrusts that each leverage existing capability to expand the IRMS offering for EMSL users: 1) develop capability for measuring ?13C of dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) in aqueous solutions, 2) refine capability for measuring ?13C and ?18O of headspace CO2, and 3) constructing a specialized module to enable ?13C and ?15N measurements of extremely small samples (~41 nmol C and ~25 nmol N). Once accomplished, this added capability can be deployed in a number of EMSL-relevant explorations including those in assessing environmental DOC turnover, tracking soil carbon cycling by plants under different environmental perturbations, using isotopic analysis of various biomarkers as a proxy for environmental conditions, and many others.
