Boron isotope analysis. A review
The Analyst, 1995Over the last ten years there has been a rapid increase in the number of studies of the boron isotope composition of natural samples. These studies have employed a variety of methods, with varying degrees of accuracy and precision. The relevant techniques are discussed in this paper and the problems associated with the measurement of boron isotope are ...

A Mass Spectrometer for Isotope and Gas Analysis
Review of Scientific Instruments, 1947A mass spectrometer suitable for routine isotope analyses of the lighter elements is described. Complete electronic circuits are given. An all metal mass spectrometer tube is employed. A null method of determining relative abundances of the elements carbon, nitrogen, and oxygen is used.

Isotopic analysis by optogalvanic spectroscopy
Journal of the Optical Society of America B, 1984We present in this paper the results obtained in our laboratory of the determination of the isotopic ratios 235U/238U, 234U/238U, and 236U/235U in natural and enriched uranium using optogalvanic detection of laser absorption. The possibility of resolving the isotopic structure of uranium absorption lines by optogalvanic spectroscopy in a hollow-cathode-

Lithogenic isotopes of strontium (Sr), neodymium (Nd), and lead (Pb) are a powerful tool for the study of the composition and origin of pre-historic ceramics and their raw materials. Despite their use in classical geochronology and isotope-geochemical provenance studies of rocks and minerals, Sr, Nd, and Pb isotope ratios have so far scarcely been used

Stable Isotope Analysis and Applications
2003The biologically important light elements are hydrogen, carbon, nitrogen, oxygen, and sulfur. Each has at least two stable isotopes, and the most abundant isotope in a pair is the lighter: 2H/1H (i.e., D/H), 13C/12C, 15N/14N, 18O/16O, and 34S/32S. Variations in isotope abundances can reveal and quantify processes in which these elements are involved.

Isotopic Analysis by Optical Spectroscopy
Isotopenpraxis Isotopes in Environmental and Health Studies, 1975The paper describes different methods of isotopic analysis for hydrogen, nitrogen, and oxygen. In the cases of the hydrogen and the oxygen, a light source with high frequency excitation and a Fabry-Perot spectrometer with photoelectric recording were employed. For the nitrogen we used a Zeiss Q-24-spectrograph, or a Zeiss SPM-2 monochromator, converted

Isotopes as a tool in biochemical analysis
1961The solution of many biochemical problems is dependent upon the availability of accurate analytical methods for the quantitative estimation of individual inorganic or organic compounds present in the particular system under consideration. Many of these naturally occurring substances fall into distinct chemical groups whose members have similar ...

Bone Sampling For Isotope Analysis
Australian Archaeology, 2002Isotope analysis has been frequently used in archaeology as means for inferring human and faunal palaeodiet and climatic change through time (Ayliffe and Chivas 1990; Pate 2000). Isotope analysis uses a variety of extraction techniques to isolate bone collagen, hydroxyapatite or cholesterol that can then be analysed through GC (gas chromatography ...

Lead Isotope Analysis and the Archaeologist
Journal of Mediterranean Archaeology, 1995There is an interesting parallel between the history of radiocarbon dating and the emerging story of lead isotope analysis. Initial euphoria soon gave way to feelings of profound scepticism, distrust and a sense of vindication on the part of more traditional humanistic archaeologists who found in the growing ambiguity over radiocarbon results a ...
