This text is designed for the undergraduate one-term quantitative analysis course for students majoring in chemistry and related fields. It deals with principles and techniques of quantitative analysis. Examples of analytical techniques are drawn from such areas as life sciences, clinical chemistry, air and water pollution, and industrial analyses. · analytical objectives, or: what analytical chemists do · basic tools and operations of analytical chemistry · data handling and spreadsheets in analytical chemistry · good laboratory practice: quality assurance of analytical measurements · stoichiometric calculations: the workhorse of the analyst · general concepts of chemical equilibrium · acid-base equilibria · acid-base titrations · complexometric reactions and titrations. · gravimetric analysis and precipitation equilibria · precipitation reactions and titrations · electrochemical cells and electrode potentials · potentiometric electrodes and potentiometry · redox and potentiometric titrations · voltammetry and electrochemical sensors · spectrochemical methods · atomic spectrometric methods · sample preparation: solvent and solid-phase extraction · chromatography: principles and theory · gas chromatography · liquid chromatography · kinetic methods of analysis · automation in measurements · clinical chemistry · century of the gene-genomics and proteomics: dna sequencing and protein profiling · environmental sampling and analysis · experiments - from Amzon
