In an article published in Analytical Chemistry in 2004, Keune and Boon [2004a] present the application of ToF-SIMS analysis to a paint cross-section. The sample used was from the panel painting The Descent from the Cross (Museo del Prado, Madrid) by the early Flemish painter Rogier van der Weyden (1399/1400 1464). Scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX) and infrared microscopy were also used to complete and confirm the results. [Pg.445]

Chong et al. [742] have described a multielement analysis of multicomponent metallic electrode deposits, based on scanning electron microscopy with energy dispersive X-ray fluorescence detection, followed by dissolution and ICP-MS detection. Application of the method is described for determination of trace elements in seawater, including the above elements. These elements are simultaneously electrodeposited onto a niobium-wire working electrode at -1.40 V relative to an Ag/AgCl reference electrode, and subjected to energy dispersive X-ray fluorescence spectroscopy analysis. Internal standardisation... [Pg.262]

Scanning electron microscopy with an energy-dispersive x-ray system accessory has been used to identify the composition and nature of minerals in coals and to determine the associations of minerals with each other. Examinations can be made on samples resulting from ashing techniques or whole coal. With this technique it is possible to identify the elemental components and deduce the mineral types present in coal samples. Computerized systems to evaluate scanning electron microscopy images have been developed and are useful in characterizing the minerals in coal mine dusts and in coal. [Pg.107]

Figure 2-2 The conjunctiva shown by scanning electron microscopy with surface mucins intact (A). On higher magnification, note the strands (B) that allow the mucins to entrap particles and remove them from the tears. The tears form a reservoir for drug compounds, including those that are delivered as particulate suspensions. (Reprinted with permission from Burstein NL.

The surface of ACF of w = 1.45 nm was modified with molecular adsorption-decomposition method using SiCU. SiCU was adsorbed on the ACF and then hydrolyzed by introduction of H2O vapour at 298 K. Afterwards, residual SiCU and produced HCl vapours were removed, and then the treated ACF was heated at 573 K. The amount of the produced hydrated silica was determined by the measurement of the weight change. The micropore structure of the silica-coated ACF was examined by N2 adsorption the t-plot analysis of the N2 adsorption isotherm showed that the micropore width decreases with the silica coating by 0.2 nm the silica coating decreased the micropore volume and surface area from 1.49 ml/g and 2280 m /g to 0.68 ml/g and 1100 m /g, respectively. No spherical silica particles were observed on the external surface of the silica-coated ACF by scanning electron microscopy with a resolution of 10 nm. Therefore, hydrated silica should be deposited entirely on the micropore walls of the ACF. [Pg.582]

Another technique we used to observe these distributions is scanning electron microscopy with energy dispersive x-ray analysis (EDAX). Concentrations of Cyasorb UV 1084, [2-2 -thiobis(4-ter -octylphenolato)-n-butylamine nickel], a nickel-containing UV absorber, were point counted to obtain nickel concentrations along a spherulite diameter. Figure 3 shows results for 1 and 4 wt % additive. This shows a uniform melt concentration, a boundary peak, a lower concentration within the spherulite, and a central dip. The resolution and sensitivity with this technique are poorer than with the optical microscopy. With every method, thin film crystallized samples and microtomed sections of bulk samples gave similar results. [Pg.269]

In this section, two recently developed magnetic imaging methods are described scanning electron microscopy with polarisation analysis, or SEMPA, and magnetic force microscopy, or MFM. [Pg.282]
