Sampling procedures and protective layers for the preservation of particulates obtained by filter collection and impingement operations |
| abstract |
A method for collecting a particulate sample from a gas or liquid particulate suspension on a substrate and keeping the collected particulate on the substrate in the same position and orientation as when it was initially collected. The substrate for collecting particulate may be covered with a coating or film that reacts with the substrate or the particulate and is optically and electron transparent. A coating or film may be placed over the collected particulate as well as, or instead of, the coating or film directly concerning the collecting substrate. A particulate sample sandwiched between two electron transparent coverings is suitable for analysis by electron microscopy. |
