CADAS

During the production of cadmium through chemical reduction from acidic solution, the formation of the highly toxic arsine gas can only be minimised by controlling the arsenic concentration in the cadmium solutions.

CADAS, a unique measuring system enables the measurement of arsenic in cadmium solutions at concentrations down to few ppb and at the same time in quasi-parallel mode, the measurement of cadmium at concentrations up to 50 g/l.
