Stable Isotope Analysis

2013
Abstract Reports on analytical methods for determining the geographical origin of agricultural products have been increasing since the 1980s [49] . The development of new techniques is highly desirable for consumers, agricultural farmers, retailers and administrative authorities.

“Stable Isotope Mixing”, a Proposal to Analyze Stable Isotopes Using a Technique Similar to the Isotope Dilution Analysis

Isotopenpraxis Isotopes in Environmental and Health Studies, 1980
A proposal (shortly expressed as stable isotope mixing) similar to the stable isotope dilution analysis is described. It deals with the determination of the stable isotope relative abundances.

Benefits of stable isotope labeling in RNA analysis

Biological Chemistry, 2019
AbstractRNAs are key players in life as they connect the genetic code (DNA) with all cellular processes dominated by proteins. They contain a variety of chemical modifications and many RNAs fold into complex structures. Here, we review recent progress in the analysis of RNA modification and structure on the basis of stable isotope labeling techniques ...

Stable isotope dilution assays in mycotoxin analysis

Analytical and Bioanalytical Chemistry, 2007
The principle and applications of stable isotope dilution assays (SIDAs) in mycotoxin analysis are critically reviewed. The general section includes historical aspects of SIDAs, the prerequisites and limitations of the use of stable isotopically labelled internal standards, and possible calibration procedures.

Stable Isotope Analysis of the Bioelements: An Introduction

Bioanalysis, 2009
The abundances of the stable isotopes of the bioelements are not constant. Subtle, but significant, variations may be induced by physical, physiological and biochemical processes. These variations may be detected and quantified. Often, isotope fingerprints are characteristic of certain processes and may reveal information concerning the sources and ...

Stable Isotope Analysis in Primatology: A Critical Review

American Journal of Primatology, 2012
Stable isotope analysis has become an important tool in ecology over the last 25 years. A wealth of ecological information is stored in animal tissues in the relative abundances of the stable isotopes of several elements, particularly carbon and nitrogen, because these isotopes navigate through ecological processes in predictable ways.

The use of stable isotopes for food web analysis

Critical Reviews in Food Science and Nutrition, 1991
General aspects in isotope biogeochemistry was summarized with emphasis on delta 15N and delta 13C contents in plants and animals in natural ecosystems. In the estuary, the variation of isotope ratios were principally governed by the mixing of land-derived organic matter, marine phytoplankton, and seagrasses.
