• Allows the easy and reliable detection of hydrogen sulphide, which occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulfide ions in solution also give a positive reaction
• The frequently used lead acetate paper (REF 90744) is toxic and needs to be declared as hazardous
• Sulfide test paper provides an alternative, which is non-toxic and safe
• Color reaction: white to brown-black
• Limit of sensitivity: 1 drop a solution containing 5mg/l Sulphide (S2-) shows a positive reaction
