Secondary specimen container

Aliquoter Aspirates appropriately sized aliquots from each original specimen container and places them into bar coded secondary specimen containers for sorting and transport to multiple analytical workstations. 

To perform the experimental measurements, several specimens containing corrosion products were taken from different parts of all of four units at Bohunice NPP. In the first step, the corrosion process in the steam generators was studied. The corrosion layers were separated by scraping the rust off the surface, and the powder samples were studied by transmission Mossbauer spectroscopy. It should be noted that the gamma spectroscopic measurements showed no evidence of the presence of low-energy y-radiation emission from the samples. Later, corrosion products were also collected from different parts of the secondary circuit components, and several filter deposits were analysed too. 

Figure 1.13. Dark-field TEM images of single-crystal calcite shocked to 85 GPa, displaying (a) the crossing of multiple twins, a large number of perfect dislocations and (b) numerous partial dislocations decorating the twin planes, (c) Secondary electron image of compacted calcite powder shocked to 85 GPa. The recovered specimen is composed of numerous foamy aggregates containing bubbles, voids, and crater-shaped objects.

Reference to the possible secondary radicals observed in mechanically degraded polymers, shows that the peroxy radical (RO ) frequently occurs. Since the polymer nuilecule contains no oxygen in many cases, the peroxy radical can only arise by reaction of the primary radical with oxygen either dissolved in the specimen or in the test environment. The detection of oxy-radicals (R0 ) by ESR spectroscopy has been reported in one instance but disclaimed in later papers ... 

An enhanced dielectric loss maximum was observed at -85°C when a polysulfone sample which contained 0.76 wt. % unassociated water and no detectable level of clustered water (<0.01 wt. %) was run (Fig. 6, curve A). An apparent low temperature broadening of the dielectric loss dispersion was noted for another polysulfone specimen with 0.76 wt. % unassociated water and an additional 0.04 wt. % clustered water (Fig. 6, curve B). However, when a polysulfone sample which contained the same amount of unassociated water as the two prior samples but had 0.16 wt. % clustered water was analyzed, it had a significantly more intense loss peak centered near -105°C (Fig. 6, curve C). We believe that this shift in loss maximum and increase in loss intensity is caused by the development of an additional secondary loss peak about 20° below the 3-transition (Figure 6). In earlier work we had observed the same phenomenon in polycarbonate where the new loss peak occurred about 40 below its 3-transition as a separate loss peak.
