Sample preparation:
The determination of dissolved mono- and trivalent gold compounds and the differentiation between Au(I) and Au(III), requires no special preparation of the sample.
 
For the determination of the Au(III)-content, treatment with Reagent Au-1 is omitted. After the usual procedure described in the attached slip, the total Au(III) and Au(I) can be calculated.
 
Analysis:
Determine with the above mentioned test kit.
 
Calculation:
Gold content in mg/l Au = analysis value in mg/l Au
