Journal ArticleDOI
IUPAC Periodic Table of the Elements and Isotopes (IPTEI) for the Education Community (IUPAC Technical Report)
Norman E. Holden,Tyler B. Coplen,John Karl Böhlke,Lauren V. Tarbox,Jacqueline Benefield,John R. de Laeter,Peter G. Mahaffy,Glenda O’Connor,E. Roth,Dorothy H. Tepper,Thomas Walczyk,Michael E. Wieser,Shigekazu Yoneda +12 more
TL;DR: The IUPAC Periodic Table of the Elements and Isotopes (IPTEI) as discussed by the authors was created to familiarize students, teachers, and nonprofessionals with the existence and importance of isotopes of the chemical elements.
Journal ArticleDOI
Novel silver-tubing method for quantitative introduction of water into high-temperature conversion systems for stable hydrogen and oxygen isotopic measurements.
Haiping Qi,Manfred Gröning,Tyler B. Coplen,Bryan Buck,Stanley J. Mroczkowski,Willi A. Brand,Heike Geilmann,Matthias Gehre +7 more
TL;DR: A new method to seal water in silver tubes for use in a TC/EA (thermal conversion/elemental analyzer) reduction unit using a semi-automated sealing apparatus can yield reproducibilities of delta(2)H and delta(18)O measurements of 1.0 per thousand and 0.06 per thousand, respectively.
Journal ArticleDOI
Isotope-abundance variations and atomic weights of selected elements: 2016 (IUPAC Technical Report)
Tyler B. Coplen,Yesha Shrestha +1 more
TL;DR: In this article, the isotopic abundances, isotope-delta values, and atomic weights for each of the upper and lower bounds of selected materials and compounds of each of these elements have been provided.
Journal ArticleDOI
A new organic reference material, l‐glutamic acid, USGS41a, for δ13C and δ15N measurements − a replacement for USGS41
Haiping Qi,Tyler B. Coplen,Stanley J. Mroczkowski,Willi A. Brand,Lauren Brandes,Heike Geilmann,Arndt Schimmelmann +6 more
TL;DR: Experimental results indicate that the chemical purity of USGS41a is substantially better than that of US GS41, and the new isotopic reference material can be used with USGS40 for isotopic analysis of biological and organic materials.
