ABSTRACT:
The invention concerns a method for the automatic analysis and determination of the amount or concentration of a specific component of a fluid in a metal-depositing bath, particularly a gold bath, wherein the fluid has several components. A quantity of bath fluid is taken from the bath in a first step. This quantity of fluid is diluted in a second step, in a third step a reaction agent and a solvent are added to a measured fractional amount of the quantity of diluted fluid during constant stirring, and, in a final step, a quantity of solvent-reaction agent mixture is conveyed to a measuring cuvette of a colorimeter and the concentration of the specific bath component is determined by means of colorimetric measurement. In addition, the invention concerns an apparatus for performing the above described method.
