Referencing strategies and techniques in stable isotope ratio analysis
Roland A. Werner,Willi A. Brand +1 more
TL;DR: An attempt to unify the strategy for referencing isotopic measurements and emphasis is given to the importance of identical treatment of sample and reference material ('IT principle'), which should guide all isotope ratio determinations and evaluations.
Journal ArticleDOI
New Guidelines for δ13C Measurements
Tyler B. Coplen,Willi A. Brand,M. Gehre,Manfred Gröning,H. A. J. Meijer,Blaza Toman,R M. Verkouteren +6 more
TL;DR: In this paper, it is recommended that δ13C values of both organic and inorganic materials be measured and expressed relative to VPDB (Vienna Peedee belemnite) on a scale normalized by assigning consensus values of −46.6
Journal ArticleDOI
Atomic weights of the elements 2013 (IUPAC Technical Report)
Juris Meija,Tyler B. Coplen,Michael Berglund,Willi A. Brand,Paul De Bièvre,Manfred Gröning,Norman E. Holden,Johanna Irrgeher,R.D. Loss,Thomas Walczyk,Thomas Prohaska +10 more
TL;DR: In this paper, the standard atomic weights of four elements have been revised based on recent determinations of isotopic abundances in natural terrestrial materials: cadmium to 112.414(4) from 112.411(8), molybdenum to 95.95(1) from 95.96(2), selenium to 78.971(8) from 78.96
Journal ArticleDOI
Isotopic compositions of the elements 2013 (IUPAC Technical Report)
Juris Meija,Tyler B. Coplen,Michael Berglund,Willi A. Brand,Paul De Bièvre,Manfred Gröning,Norman E. Holden,Johanna Irrgeher,R.D. Loss,Thomas Walczyk,Thomas Prohaska +10 more
TL;DR: The Table of Isotopic Compositions of the Elements (TICE) was updated in 2013 by the International Union of Pure and Applied Chemistry (IUPAC) as mentioned in this paper.
Journal ArticleDOI
Online Sulfur-Isotope Determination Using an Elemental Analyzer Coupled to a Mass Spectrometer
TL;DR: In this paper, an online method for S-isotope analysis is described, where samples are combusted in an elemental analyzer and SO 2 is separated from other combustion gases by gas chromatography, and the gases enter the ion source of the mass spectrometer through a split interface.
