What forms of hydrogen sulfide will be detected by the model HS-C hydrogen sulfide test kit?
Forms of hydrogen sulfide detected by the HS-C test kit
The kit measures H2S and un-complexed ionic or free S2- present in the sample. Under the conditions of the test pH the S2- is converted to H2S and swept or effervesced out. The kit will not determine complexed or insoluble metal sulfides at the pH of the Alka-Seltzer.
