The test paper allows the quick and easy detection of hydrogen sulphide. This gas occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulfide containing solutions also give a positive reaction.

Lead acetate is toxic and the test paper needs to be declared as hazardous. The technically equivalent Sulfide test paper (REF MN90761) is a non-toxic and safe alternative.

Limit of sensitivity: 1 drop a solution containing 5mg/l Sulfide (S2–) shows a positive reaction
