GGR Handbook of Rock and Mineral Analysis Chapter 2 (Part 2) Analysis of Geological Materials – 2: Pre‐Concentration and Separation Procedures

This chapter (Analysis of Geological Materials – 2: Pre‐Concentration and Separation Procedures) is a contribution to the Geostandards and Geoanalytical Research Handbook of Rock and Mineral Analysis – an online textbook that is a fully revised and updated edition of A Handbook of Silicate Rock Analysis (P. J. Potts, 1987, Blackie, Glasgow). In Chapter 2, Part 2 (from Section 1 of the handbook dealing with fundamentals of measurement and instrument design) the principles and procedures of ion exchange chromatographic techniques and processes are first examined followed by a review of their application to isotope measurement by TIMS and MC‐ICP‐MS for radiogenic and stable isotope systems. Determination of platinum‐group and rare earth elements by ICP‐MS is also covered. Following this, liquid‐liquid (solvent) extraction and extraction chromatography are examined, including a review of EXC resins in the analysis of silicate materials. Part 2 Chapter 2 concludes with a treatment of coprecipitation and vapour generation (for hydrides, mercury and osmium).
