Sulphide test paper • Quick and easy determination of hydrogen sulphide • The test paper allows the easy and reliable 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 ions in solution also give a positive reaction. • The frequently used lead acetate paper is toxic and needs to be declared as hazardous. • Sulfid test paper provides an alternative which is non toxic and safe. Product data • Presentation: Reel of 5 m length and 7 mm width • Color reaction:white to brown-black • Limit of sensitivity :1 drop a solution containing 5mg/l Sulphide (S2-) shows a positive reaction
