An excellent, accessible overview of what surface scientists do, the problems they address and how they link to technological needs is in a published lecture by a chemist, Somorjai (1998). He concisely sets out the function of numerous advanced instruments and techniques used by the surface scientist, all combined with UHV (LEED was merely the first), and exemplifies the kinds of physical chemical issues addressed - to pick just one example, the interactions of co-adsorbed species on a surface. He also introduces the concept of surface materials , ones in which the external or internal surfaces are the key to function. In this sense, a surface material is rather like a nanostructured material in the one case the material consists predominantly of surfaces, in the other case, of interfaces. 

In this chapter, we overview basic techniques for making nanoscale adhesion and mechanical property measurements. Both quasi-static and dynamic measurements are addressed. In Section 2 of this chapter, we overview basic AFM instrumentation and techniques, while depth-sensing nanoindentation is overviewed in Section 3. Section 4 addresses recent advances in instrumentation and techniques... 

Mass Spectra and Chemical Structure While there are a number of books (Refs 16, 30, 49 64) already referred to, which deal with details of the instrumentation and techniques of mass spectrometry, there are several concise introductory texts (Refs 10, 21 52) on the interpretation of mass spectra. Still other recent books deal comprehensively with organic structural investigation by mass spectrometry. One of these (Ref 63) discusses fundamentals of ion fragmentation mechanisms, while the others (Refs 7, 15, 20, 28 29) describe mass spectra of various classes of organic compounds. In the alloted space for this article methods of interpretation of mass spectra and structural identification can not be described in depth. An attempt is, therefore, made only to briefly outline the procedures used in this interpretation... 

The study of reactions with rates that He outside the time frame of ordinary laboratory operations requires specialized instrumentation and techniques. This chapter presents the wide range of methods currently in use for very fast reactions. Extraordinarily slow reactions, on the other hand, have received very little attention. For them, one may resort to measuring a tiny concentration of product over normal times, as in the method of initial rates. 

For detection, MS is rapidly becoming the method of choice for multiclass, multiresidue analysis owing to its many advantages, recent improvements in technology, and availability of cost-effective commercial instrumentation. Detection systems in general are continually being improved, and in combination with the improvements in chromatographic instruments and techniques, an exceptionally low limit of detection (LOD) is possible for pesticide residues. 

Semi-preparative HPLC" was then used to further purify the extract. Instrumentation and techniques were the same as described previously. Active compounds were contained in the 7-11 min fraction (data not shown). 

The chemical world is often divided into measurers and makers of molecules. This division has deep historic roots, but it artificially impedes taking advantage of both aspects of the chemical sciences. Of key importance to all forms of chemistry are instruments and techniques that allow examination, in space and in time, of the composition and characterization of a chemical system under study. To achieve this end in a practical manner, these instruments will need to multiplex several analytical methods. They will need to meet one or more of the requirements for characterization of the products of combinatorial chemical synthesis, correlation of molecular structure with dynamic processes, high-resolution definition of three-dimensional structures and the dynamics of then-formation, and remote detection and telemetry.

These assignments represent formidable tasks for the experimentalists, but recent developments in instrumentation and techniques suggest that substantial progress should be made soon. 

For the most reliable results, chamber environment should be monitored continuously with instruments and techniques equivalent to those used in ambient-air monitoring networks (see Chapter 6). Calibration of instruments should follow recommendations by appropriate agencies and be checked by cross comparisons with those in other analytic laboratories. 

Over 1000 articles dealing with atomic absorption are published each year making a truly comprehensive review a difficult task. What the authors have chosen to do is to discuss the recent advances in instrumentation and technique of particular interest to those persons involved in the analysis of air and water samples for trace metal toxins.
