The catalysts were characterized by inductively coupled plasma emission spectroscopy (ICP-ES Perkin Elmer Optima 3300RL) to determine cobalt content, x-ray diffraction (XRD Bruker A-500) with crystallite size determination using the Rietveld method, and temperature-programmed reduction (Zeton Altamira AMI-200) using 30 ml/min 10% H2/Ar and a ramp rate of 10°C/min.

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. 

Characterization of the modified plastocyanins was by Inductively Coupled Plasma Emission Spectroscopy to analyze for Ru and Cu (1 1 ratio), and by HNMR spectroscopy. In the HNMR characterization the C2H resonance of His59 at 8.2 ppm is seen to be lost due to paramagnetic line broadening effect of the attached Ru(III), Fig. 13 [50]. In a further test it is known that the His59 s of both native plastocyanins react with diethyl pyrocarbonate (DEPC) to give an JV-ethoxyhistidine derivative, (12), which absorbs strongly at 238 nm (e 2750M- cm-i), Fig. 14 [133]. 

Li or a Li compound in the flame gives a bright crimson color due to its emission of670.8 nm photons produced by the short-lived species LiOH. This is the property that allows for the spectrophotometric determination of Li by atomic absorption spectroscopy (AAS) down to 20 ppb. Inductively-coupled plasma emission spectroscopy (ICPAES), inductively-coupled plasma mass spectroscopy (ICPMS), and ion chromatography (IC) improve this limit to about 0.1 ppb. A spot test for detection of Li down to 2 ppm is provided by basic KIO4 plus FeCl3. 

Analysis. Be can be quantitatively determined by colorimetry down to 40 ppb using eriochrome cyanine R or acetylacetone. The sensitivity may be improved by electrothermal absorption spectroscopy (ETAS) to 1 ppb and to 0.1 ppb by inductively-coupled plasma emission spectroscopy (ICPES) or inductively-coupled plasma mass spectroscopy (ICPMS). A simple spot test for qualitative detection of Be is one with quinalizarin in alcoholic NaOH which can detect 3 ppm. The color is produced by both Be and Mg. If the color persists after the addition of Br2 water. Be is present. If the color is bleached. Mg is indicated. 

Analysis. The green flame color of Ba is an indicator that it may be determined readily by atomic emission or absorption spectroscopy. Ba is quantitatively determined by colorimetry down to 1 ppm using o-cresolphthalein at a pH of 11, by atomic absorption spectroscopy (AA ) to 200 ppb, to 10 ppb by electrothermal absorption spectroscopy (ETA ), and to 0.1 ppb by inductively-coupled plasma emission spectroscopy (ICPE ) and inductively-coupled plasma mass spectroscopy (ICPM ). A spot test for Ba which extends to 30 ppm is provided by a controlled combination of KMn04, H2 04, and H2 03.

An example of the application of dynamic ion-exchange chromatography for the direct separation of rare earths is shown in Fig. 1.22. The sample was a sodium hydroxide leach solution from an aluminium processing operation and contained high concentrations of sodium, iron and aluminium. Due to matrix interference, these solutions could not be accurately analysed by inductively coupled plasma emission spectroscopy. Fig. 1.22 shows the chromatogram when the sample was separated by dynamic ion-exchange... 

A comparison of the results obtained by high pressure liquid chromatography (HPLC) with results obtained by other techniques such as inductively coupled plasma emission spectroscopy (ICPES) showed good agreement and HPLC procedures are found to be economical in terms of analysis time. 

In an earlier paper (13), the INAA procedure was described and compared to the chemical analysis of bone by using inductively coupled plasma emission spectroscopy (ICPES). The ICPES technique required dissolution of the ashed sample before analysis, but otherwise the techniques proved to be quite comparable. In this study, some of the samples were analyzed by using X-ray fluorescence (XRF) to determine whether there was adequate sensitivity for the study of contamination in archaeological bone.
