“…Phillips and Timms (9) employed the quantitative gas chromatographic determination of silicon and germanium tetrachlorides produced by reaction of silanes and germanes with gold(III) chloride as a measure of silicon and germanium in mixed hydrides. Dennison and Freund (1) described the analysis of SnClr AsCls mixtures, and Sie, Bleumer, and Rijnders (11), recently determined a number of metal chlorides in mixtures quantitatively. Juvet and coworkers (5, 14) described a sensitive and selective, corrosion-free, flame photometric detection system giving linear response for metal halides over four orders of magnitude.…”
