Further to Tom Conroy's response, there are two papers published by
the (U.S.) Bureau of Standards:

    Technologic Papers of the Bureau of Standards
    No. 20: "Determination of Sulphur in Illuminating Gas" by R.S.
    McBride and E.R. Weaver, March 7, 1913.

    Technologic Papers of the Bureau of Standards
    No. 34: "Determination of Ammonia in Illuminating Gas" by J.D.
    Edwards, March 2, 1914

The role of deliquescent salts should also be examined.
