Geochemical and Cosmochemical Materials

Chemical studies of L chondrites. VI: variations with petrographic type and shock-loading among equilibrated falls

“…In fact, this is not the case today. In reviewing applications of all analytical techniques to geochemistry and cosmochemistry in 1997-1999, Lipschutz et al (1999) noted that ICPMS was already a significant tool for geochemical analyses of many elements at levels similar to those in meteorites. Subsequently, ICPMS has displaced many techniques used for geochemical Huston and Lipschutz (1984); 3.…”

“…2893 Chemical studies of L chondrites elemental analysis (Lipschutz et al, 2001 so that NAA techniques may be considered obsolescent for all but perhaps the most volatile elements. This revolution has not yet taken place in cosmochemical research for reasons, we suspect, other than the general quality of ICPMS data.…”

Comparison of Methods for Measurement of Organic Compounds at Ultra-Trace Level: Analytical Criteria and Application to Analysis of Amino Acids in Extraterrestrial Samples

“…At present, no one analytical method, sample analog or reference material, or intercomparison network exists for extraterrestrial organic matter analysis, which would allow a proper evaluation of the accuracy of measurements as is done in other fields [i.e., a network exists for mineral analysis (Lipschutz et al, 2001)]. Consequently, we propose that the accuracy of measurements for each sample analysis be determined systematically by adding a known amount (at various concentration levels) of well-defined compounds in the sample or sample extract.…”

Analytical Chemistry of Element Determination (Non‐Nuclear and Nuclear)

“…Applications reviews cover targeted materials while in alternating years fundamental reviews deal with specific analytical techniques (the latter are referenced in later sections in this chapter on specific techniques). The following are several of the most recent (1991 to 2002) applications reviews in Analytical Chemistry on biological, environmental and related materials: Anderson (coordinator) (1999) Clinical chemistry; Mansfield et al (1999) Petroleum and coal; Fox (1999) Air pollution; Richardson (1999) Water analysis; Clement and Yang (1999) Environmental analysis; Lipschutz et al (1999) Geochemical and cosmochemical materials;MacCarthy et al (1995) Water analysis;Chang et al (1995) Food;Clement et al (1991Clement et al ( ,, 1995Clement et al ( , 1997aClement et al ( , 1999 Environmental analysis; Jackson et al (1995) Geological and inorganic materials; Sithole (1995) Pulp and Paper; Anderson and Van Lente (coordinators) (1995) Clinical chemistry; Jackson et al (1991Jackson et al ( , 1993 Equally impressively comprehensive reviews on atomic spectrometric techniques appear regularly in the Journal of Analytical Atomic Spectrometry; these are referred to in appropriate determinative technique sections in this chapter. Other reviews in this journal target materials and emphasize various atomic spectrometric techniques for their analyses.…”
