An introductory manual that explains the basic concepts of chemistry behind scientific analytical techniques and that reviews their application to archaeology. It explains key terminology, outlines the procedures to be followed in order to produce good data, and describes the function of the basic instrumentation required to carry out those procedures. The manual contains chapters on the basic chemistry and physics necessary to understand the techniques used in analytical chemistry, with more detailed chapters on atomic absorption, inductively coupled plasma emission spectroscopy, neutron activation analysis, X-ray fluorescence, electron microscopy, infrared and Raman spectroscopy, and mass spectrometry. Each chapter describes the operation of the instruments, some hints on the practicalities, and a review of the application of the technique to archaeology, including some case studies. With guides to further reading on the topic, it is an essential tool for practitioners, researchers, and advanced students alike.

In this section we shall recall some of the basic concepts and discuss the problem of stability of non-equilibrium systems. This will lead us to an idealized, simple theoretical model of low pressure plasma which can be mathematically treated.

Let us summarize now the basic concepts of plasma physics useful for the description and understanding of plasma chemistry processes. 

The comments by Drs. Heikki Seppa, Jorma Vuorinen, and Antti-Pekka Tulkki from the University of Technology, Otaniemi, Finland, and those by Dr. Petri Vainio from the Department of Medical Chemistry, University of Helsinki, are appreciated. The basic concepts have been presented in the Soviet-Finnish Symposium on Nuclear and Plasma Membranes, Helsinki, Finland, March 18-19 1982, and in the Scandinavian Workshop on Plasma Lipoproteins, Punkahaqu/Helsinki, Finland, June 22-29, 1982, as well as in lectures delivered by PKJK while a visiting lecturer of the Soviet Academy of Sciences, Moscow, USSR, March 12-19, 1983. Financial support was provided by the Finnish State Medical Research Council and the University of Helsinki. 

Californium-252 ( Cf) plasma desorption (PD) ionization, introduced in 1974 by Torgerson and co-workers [15], soon found applications for the analysis of large nonvolatile, polar, and thermally labile molecules [16,17]. Because of the pulsed nature of the plasma beam, PD is well adapted to TOF mass spectrometry. The basic concept of PD-TOFMS is illustrated in Figure 2.5. In this technique, the sample is deposited as a solid film on a thin aluminum foil or other suitable... 

Whereas classical pharmacokinetic models utilize a relatively small number of compartments (see Figure. 6.10), PBPK models seek to mimic physiological pathways and processes controlling the time-course of plasma and tissue concentrations and represent the state-of-the-art in advanced pharmacokinetic systems analysis. Basic concepts of PBPK modeling and a hybrid application to composite nanodevice pharmacokinetics are described in this section. 

The nebulization concept has been known for many years and is commonly used in hair and paint spays and similar devices. Greater control is needed to introduce a sample to an ICP instrument. For example, if the highest sensitivities of detection are to be maintained, most of the sample solution should enter the flame and not be lost beforehand. The range of droplet sizes should be as small as possible, preferably on the order of a few micrometers in diameter. Large droplets contain a lot of solvent that, if evaporated inside the plasma itself, leads to instability in the flame, with concomitant variations in instrument sensitivity. Sometimes the flame can even be snuffed out by the amount of solvent present because of interference with the basic mechanism of flame propagation. For these reasons, nebulizers for use in ICP mass spectrometry usually combine a means of desolvating the initial spray of droplets so that they shrink to a smaller, more uniform size or sometimes even into small particles of solid matter (particulates). 

In Chapters 1 and 2, we not only covered the basics of thermal and plasma-enhanced CVD, but we described the general reactor configurations that researchers have explored over the years. From these concepts have come a few production CVD reactors that satisfy the commercial needs of the integrated circuit manufacturing process. 

In addition to thermally-created CVD films, much work has been done using glow discharges to modify the deposition. Therefore, Chapter 2 reviews the fundamentals of plasma-enhanced CVD (PECVD). Initially, the basic character of a plasma is covered. Then we discuss the influence of the reactor configuration on the plasma behavior and PECVD deposition. The two major PECVD reactor systems are reviewed, and then several new concepts are considered.
