Abstract : The degree of chlorination of an organic material affects both its volatility and resistance to oxidation. Each of these properties makes difficult the selection of a quantitative means of mineralization for elemental microanalysis. Since the analysis for chlorine content invariably is finished with the chlorine in chloride form, a reduction method of mineralization is indicated. Several mineralization methods were experimentally compared. Oxygen flask combustion using pressure-sensitive tape as sample wrapper yielded good results. Exactly suited techniques were developed and are given for solids and nonvolatile and volatile liquids. Applying precise blank control, these techniques were applied experimentally. For further improvement, properties of various tapes were studied and a best tape was selected and tested. This tape was used in the analysis of carbon tetrachloride, chloroform, and methylene chloride. These and other experimental results are given. (Author)
