Could you please tell me how to use this test paper properly? Do they need to be moistened with acetate buffer before testing the sample?

For optimal results you should moisten the papers with acetate buffer prior to testing the sample. If you are using these strips to test for sulfide prior to distilling/analyzing samples for cyanide you must follow the method procedure and use the acetate buffer. For other samples, if you do not have acetate buffer available you will still be able to get results from the test papers. The reaction and color development may be slightly slower or more difficult to detect but it will be present.

Could you please tell me what is the lowest concentration of sulfides can be detected by Johnson lead acetate test paper.

The minimum detection level is somewhat dependant on the visual acuity of the observer. Generally speaking a level of 1-3 mg/L will darken the strip enough to be observed. This range may change somewhat depending on lighting and color of the sample tested.
