Precious metals
in the test


Chemical reaction reveals precious metal content to our experts

In titration, a dissolved element is chemically changed by the addition of a reaction solution. This change is tracked by means of an indicator. While the reaction solution is added, the indicator shows that the reaction has come to an end. This endpoint allows a conclusion to be drawn about the content of the element being searched for.

Our special process for low soluble silver compounds

A method of titration frequently encountered in precious metal analysis is titration according to the Volhard method. Titration according to the Volhard method belongs to the precipitation titrations. This method of analysis is based on the low solubility of some silver compounds. Thus, with the help of laboratory instruments, the silver content can be determined manually or automatically by using a Dosimat and a measuring probe.

The perfect application for the determination of silver and halogens

Titrations are often used for the determination of metals with a concentration above 10 per cent. Titrations are thus ideally suited for the determination of silver in alloys or of lead in lead concentrates. Halogens are non-metals such as fluorine, chlorine, bromine, and iodine.
