uniformity graph The coloured lines indicate temp measurement and therefore show good uniformity from front (left) to rear (right) of chamber
ashing ~ applications some typical examples: • ashing enviromental samples ~ Yorkshire Water Co • ashing paint samples ~ Nippon Paint Co • ashing rubber samples ~ Avon Rubber Co • ashing of food containers ~ Rexon Packaging Co • After ashing the samples are analyised using IC or AA
