Analytical ChemistryWiley, 6 gen 1994 - 840 pagine Extensively revised and updated, this edition is concerned primarily with quantitative analysis techniques. Describes how to design an analytical method, how to obtain a laboratory sample that is representative of the whole and to prepare it for analysis, what measurement tools are available, automated analyses and the statistical significance of the analysis. New and expanded topics include heterogeneous equilibria, diode array spectrometers, fiber-optic sensors and solid-phase extraction. |
