The minimum N concentration for an accurate determination of the N-15 abundance is 7 mu mol/L for nitrite and nitrate, with a relative standard deviation (RSD) of repeated measurements of <1%, and 70 mu mol/L with an RSD < 0.4% in the case of ammonium. The SPIN-MIMS system provides a wide dynamic range (up to 3500 mu mol/L) for all three N species for both isotope abundance and concentration measurements. The comparison of parallel measurements of N-15-labeled NH4+ and NO3- from soil extracts with the denitrifier method and the SPIN-MIMS system shows a good agreement between both methods."],["dc.description.sponsorship","Thunen-Institut; German Research Foundation [DY 81/5-1]"],["dc.identifier.doi","10.1021/acs.analchem.7b00724"],["dc.identifier.isi","000403036800059"],["dc.identifier.pmid","28481532"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42345"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Amer Chemical Soc"],["dc.relation.issn","1520-6882"],["dc.relation.issn","0003-2700"],["dc.title","Measuring N-15 Abundance and Concentration of Aqueous Nitrate, Nitrite, and Ammonium by Membrane Inlet Quadrupole Mass Spectrometry"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
