Among
such may be named the detection of traces of phosphine in acetylene which
has passed through a purifier with a view to ascertaining if the
purifying material is exhausted, and the estimation of the amount of air
or other diluents in stored acetylene or acetylene generated in a
particular manner. Advice on these points should be sought from competent
analysts, who will already have the requisite information for the
carrying out of any such tests, or know where it is to be found. The
analyses in question are not such as can be undertaken by untrained
persons. The text-book on "Gas Manufacture" by one of the authors gives
much information on the operations of gas analysis, and may be consulted,
along with Hempel's "Gas Analysis" and Winkler and Lunge's "Technical Gas
Analysis."
