@article{JRC42018, address = {CHICHESTER (ENGLAND)}, year = {2008}, author = {Accoe F and Berglund M and Geypens B and Taylor P}, abstract = {On-line determination of the oxygen isotopic composition (delta 18O value) in organic and inorganic samples is commonly performed using a thermal conversion elemental analyzer linked to a continuous flow isitope ratio mass spectrometer (TC-EA-IRMS). Accurate delta 18O analysis of N-containing compounds (like nitrates) by TC-EA-IRMS may be complicated because of interference of the N2-peak on the m/z 30 signal of the CO peak, which s used for calculation of the delta 18O value. The aim of this study was to evaluate the effectiveness of different strategies to eliminate this interference. }, title = {Methods to Reduce Interference Effects in Thermal Conversion Elemental Analyzer/continuous Flow Isotope Ratio Mass Spectrometry Delta18O Measurements of Nitrogen-containing Compounds}, type = {}, url = {}, volume = {22}, number = {14}, journal = {RAPID COMMUNICATIONS IN MASS SPECTROMETRY}, pages = {2280-2286}, issn = {0951-4198}, publisher = {JOHN WILEY & SONS LTD}, doi = {10.1002/rcm.3609} }
