The Analyst's Handbook offers a true treasure trove for practitioners in the fields of analytical chemistry, food and environmental chemistry, clinical chemistry, materials research, and biotechnology, with its very current and practice-oriented contributions on the fundamentals, methods, and applications of analytical-chemical procedures. The concise presentation and deliberately selected literature references enable specialists to efficiently familiarize themselves with and adapt the methodology, while non-specialists can quickly gain an overview. The focus of the volume is on the analytical authenticity assessment of natural fragrance and flavor substances using isotope ratio mass spectrometry and gas chromatography, as well as capillary electrophoresis and elution and extraction methods for mobile contaminants in solids.
