ABSTRACT:
A device and method for determining the concentration of dicyanoaurate anions in a solution is disclosed. The device includes a semipermeable membrane formed from a material permeable to dicyanoaurate anions. The material may be comprised of an organopolysiloxane-polycarbonate block copolymer and a complexed salt of the dicyanoaurate anion.
