Surface contamination, with

Because of the extreme surface sensitivity of static SIMS, care should always be exercised not to handle the samples. Clean tools and gloves should be used always to avoid the possibility of contaminating the surface. While it is possible to remove surface contamination with solvents like hexane, it is always desirable not to clean the surface to be analyzed.

TOF-SIMS images (Figs. 13.5 and 13.6) illustrate the ability to detect changes in the dispersion (uniform or presence of metal clusters) of the active phase in supported-oxide catalysts. Figure 13.5 shows nearly uniform distribution of molybdenum. The surface contamination with NH4+ ions coming from a precursor, which were not removed during the catalyst preparation process, is also observed. Cobalt clusters in the range of several micrometers are clearly visible in Fig. 13.6. 

Note Surfaces contaminated with HD and then rinse decontaminated may evolve sufficient mustard vapor to produce a physiological response. 

In 1997, the U.S. Department of Energy (DOE) released bench-scale results of an integrated TechXtract system for decontaminating surfaces contaminated with radionuclides. The overall economics of the system were evaluated. Costs for the system compared favorably with existing options for radioactively contaminated scrap metal (D177859, p. 3). 

SR spotty polyurethane. This appears on the metal surface looking like splattered-on polyurethane. It is caused by either surface contamination with dust or the fact that the sprayed-on adhesive has dried as it leaves the spray nozzles.

In the alloy having 50 atom % hydrogen, patterns appeared at 700° C., and the unidentified pattern previously designated as Unknown A was found at 815° C. Some faint U02 patterns were also observed, probably resulting from slight surface contamination with oxygen.

Small Areas Puddles of liquid must be contained by covering with vermiculite, diatomaceous earth, clay, fine sand, sponges, paper towels or cloth towels. Remove all material and place in a container. Decontaminate the area with copious amounts of full strength household bleach. A 10 weight percent HTH pool bleach/water slurry may be substituted for the bleach solution. Removal of porous material, including painted surfaces, that may have absorbed Vesicant liquid may be required as these materials could continue to re-release vapor after exposure has ceased. Surfaces contaminated with Vesicants and only rinsed may still evolve sufficient agent vapor to produce a physiological response. 

It was our conclusion that films evaporated from this wire were surface-contaminated with oxygen and that the oxygen originated from the wire. 

Details of specific requirements relating to particular applications are given in chapters 7 to 12 and 14. In general terms, limestone products should have the required particle size distribution and, for most applications, be free of excessive surface contamination with clay or other fine particles. For use as an aggregate, it is essential that the strength and durability are adequate. Particle shape may also be a factor. The chemical analysis is important for certain applications.
