Analytical chemistry today is almost entirely instrumental analytical chemistry and it is performed by many scientists and engineers who are not chemists. Analytical instrumentation is crucial to research in molecular biology, medicine, geology, food science, materials science, and many other fields. With the growing sophistication of laboratory equipment, there is a danger that analytical instruments can be regarded as "black boxes" by those using them. The well-known phrase "garbage in, garbage out" holds true for analytical instrumentation as well as computers. This book serves to provide users of analytical instrumentation with an understanding of their instruments. This book is written to teach undergraduate students and those working in chemical fields outside analytical chemistry how contemporary analytical instrumentation works, as well as its uses and limitations. Mathematics is kept to a minimum. No background in calculus, physics, or physical chemistry is required. The major fields of modern instrumentation are covered, including applications of each type of instrumental technique. Each chapter includes: A discussion of the fundamental principles underlying each technique Detailed descriptions of the instrumentation. An extensive and up to date bibliography End of chapter problems Suggested experiments appropriate to the technique where relevant This text uniquely combines instrumental analysis with organic spectral interpretation (IR, NMR, and MS). It provides detailed coverage of sampling, sample handling, sample storage, and sample preparation. In addition, the authors have included many instrument manufacturers’ websites, which contain extensive resources.

About one-half of the report concerns Standard Reference Materials (SRMs). Spectrophotometric measurements of bilirubin and of 'azobilirubin' in simple solvents and in serum or proteins are given much attention. D-Glucose for use as a clinical standard is examined by gas--liquid chromatography and differential scanning calorimetry. Additional compounds for development as SRMs are cortisol, 4-hydroxy-3-methoxy-DL-mandelic acid (VMA), D-mannnitol, and the reduced form of beta-NAD. Some properties thus far studied on commercially available specimens are reported. In carbohydrate research programs, the purity of 1,2:4,5-di-O-isopropylidene-D-fructose and the importance of using it pure for conversion into pure D-psicose are described. The proton magnetic parameters of the unquestioned, skew conformation of 3-O-benzoy1-1,2,4-O-benzylidyne-alpha-D-ribopyranose are analyzed. Iterative analysis of p.m.r. spectra and the conformations of some D-glucose derivatives are described. A number of other topics are described: iodination of beta-diketones with periodic acid, and reactions of bilirubin, hemin, and related bile pigments; also, some work on the detection of polynitro aromatic compounds is given.
