This chapter presents an elementary discussion of the theory, instrumentation, and practice of EPR-electrochemical studies. We recite the usual disclaimers about limitations of space to explain that the subject cannot be covered comprehensively here. The selected bibliography at the end of the chapter is broken down into broad categories to guide the interested reader to specific topics. The student who wishes a more thorough discussion of the general subject at an elementary level may find McKinney s review [1] helpful.

Atomic absorption sample preparation procedures applied to archaeological samples can be streamlined. Important factors include sample preparation, sample size, sample decomposition, standards, instrumentation, and practical and conceptual applications of atomic absorption analysis. On a comparative basis the sample preparation procedure reported was convenient and rapid the AAS instrumentation proved to be flexible, sensitive, rapid, and inexpensive in the analysis of archaeological materials. 

Liquid chromatography-mass spectrometiy (LC-MS) based on atmospheric-pressure ionization (API) was demonstrated as early as 1974 (Ch. 3.2.1). However, it took until the late 1980 s before API was starting to be widely applied. Today, it can be considered by far the most important interfacing strategy in LC-MS. More than 99% of the LC-MS performed today is based on API interfacing. In this chapter, instrumentation for API interfacing is discussed. First, vacuum system for MS and LC-MS are briefly discussed. Subsequently, attention is paid to instrumental and practical aspects of electrospray ionization (ESI), atmospheric-pressure chemical ionization (APCI), and other interfacing approaches based on API. The emphasis in the discussion is on commercially available systems and modifications thereof. Ionization phenomena and mechanisms are dealt with in a separate chapter (Ch. 6). Laser-based ionization for LC-MS is briefly reviewed (Ch. 5.9).

In the present text only brief outlines of these methods can be presented. For more detailed discussion of the theoretical principles, instrumentation and practice of atomic spectrometry, modern texts of instrumental analysis should be consulted, e.g. Daniel C. Harris Quantitative Chemical Analysis, 3rd edn, W. H. Freeman and Co, 1991, chapters 20 and 21. 

TEM approaches. The scope of this chapter prevents an in-depth description of standard TEM techniques or specific 3D reconstruction methodologies. Instead we concentrate on providing an appropriate conceptual framework, together with appropriate references to more in-depth sources, combined with selected practical tips and protocols for sample preparation methods routinely used within our laboratory. The existence of several National Institutes of Health regional facilities whose charge is to provide expertise, instrumentation, and practical guidance for TEM 3D reconstruction means that the techniques described in this chapter should be widely accessible to individual investigators.

Standard sampling instruments and procedures have been developed by OSHA with the assistance of the National Institute of Occupational Safety and Health (NIOSH). These are developed to have OSHA industrial hygienists and compliance officers operate under a necessary standardized practice to determine compliance with standards. A principal consideration in their selection has been simplicity in operation and direct-reading response. Both of these requirements are important for any inspectorate as these individuals must engage in considerable travel and desire to ascertain compliance stanis as soon as possible. However, these OSHA sampling instruments and practices are not necessarily the optimum for individual plant use to provide the most accurate data,...
