Trace Analysis, Volume 2 is devoted to critical discussions of selected topics in organic and inorganic analytical chemistry including instrumentation, techniques, and applications to the detection, identification, and quantitation of trace quantities of substances in a large variety of sample materials. The volume presents expositions of selected topics on trace analysis such as vitamin analysis in foods and tissues; liquid chromatography - mass spectrometry with emphasis on approaches to interfacing; approaches to the isolation and concentration of trace organics from aqueous samples; and the advantages of unmodified silica gel for the chromatographic separation of polar substances. The book will be highly useful to both organic and inorganic chemists.
