Applications of Stable Isotope Analysis in Zooarchaeology: An Introduction

International Journal of Osteoarchaeology, 2014
ABSTRACTThis special volume brings together works that present cases of studies that combine analysis of stable isotopes and zooarchaeology in different areas of Chile and Argentina, with special emphasis on the latter. These analyses were conducted in order to examine paleoecological conditions and interactions between humans and animal resources in ...

Geographical Origin Identification of Tequila Based on Multielement and Stable Isotopes

Journal of Food Quality, 2021
To explore the regional characteristics of multielement and stable isotopes in tequila and the viability of tracing the geographical origin, both inductively coupled plasma mass spectrometry (ICP-MS) and stable isotope ratio mass spectrometry (IRMS) were

Mass spectrometric measurement of hydrogen isotope fractionation for the reactions of chloromethane with OH and Cl [PDF]

Atmospheric Chemistry and Physics, 2018
Chloromethane (CH3Cl) is an important provider of chlorine to the stratosphere but detailed knowledge of its budget is missing. Stable isotope analysis is a potentially powerful tool to constrain CH3Cl flux estimates.
