X-ray spectrometry energy dispersive

Similarly, Posfai et al. (1998) carried out AFM and TEM studies of aerosol particles collected over the North Atlantic Ocean. The size of the particles measured under the vacuum conditions of the TEM were smaller than those measured by AFM, due to evaporation of water from the particles. However, the TEM images also showed halos around the particles at the same diameters as the AFM measurements, suggesting that the particles under ambient conditions had an organic coating. This was supported by energy-dispersive X-ray spectrometry (EDS), which showed that these residues contained S, O, and C (although at least some of the C signal may have been due to the substrate).

Elemental analyses of these samples were obtained by energy dispersive x-ray spectrometry (EOS). Total sulfur, ash, and pH of the samples is also reported, and colorants were determined. The presence of mordants, weighting materials, and colorants is discussed with reference to the embrittlement of the silk. The connection between fiber deterioration and color is discussed as well as the effects of contemporary manufacturing treatments on the present fiber condition.

An elemental analysis of the anodic films performed both with AES and SEM energy-dispersive X-ray spectrometry (EDXS) showed that the films had 11 at. % average deviation from the starting material stoichiometry towards carbon enrichment, and contained 6 at.% of oxygen and 9 at.% of fluorine. Also, current-voltage (I-V) measurements of the speci-men/electrolyte junction (performed under illumination) before and after the treatment revealed enhancement of photoresponse from the SiC surface covered with the anodic film as compared with the starting material. 

Instrumental neutron activation lends itself to on-stream applications. Figure 4.1 shows a schematic representation of on-stream and discrete sample instrumental activation analysis. In the on-stream example the sample flows through an irradiation coil and then through a counting coil. In the discrete sample application, the sample, in a suitable container, is first irradiated and then taken close to the radiation- detector. The radiation detectionanalyzing system shown here is similar to the one described for energy dispersive X-ray spectrometry.
