Abstract
The invention provides an on-stream method and apparatus for analyzing of the concentrations of chemical components in a bath, especially in an electroplating bath, contained in one or more processing tanks. Moreover, the information obtained by such analysis of a single bath or of multiple baths may be efficiently employed to control such concentrations in the bath or respective baths, for example, by controlling the addition of one or more additives. The apparatus comprises a multi-steam sampling value and a computer for controlling the operation of said value. The computer also controls means for adding material to the baths in order to maintain the parameters thereof.
