Abstract

Chemical methods are presented for routine identification and size estimation of water- or acid-soluble particles of a number of chemical species, using spot test techniques and light or electron microscopy. Although the work reported here is primarily that of the authors and their co-workers, a brief literature survey of work in other laboratories is included.
