No interference by:
5 ppm aniline
10 ppm benzylamine
5 ppm toluene
20 ppm benzene
Mercaptans also discolor the indicating layer.
|Before carrying out the measurement the lower reagent ampoule must be broken and the liquid transferred to the indication layer, so that it changes color to yellow. Next, the upper reagent ampoule must be broken and the liquid transferred to the indication layer, so that it returns to a white color. After performing 25 pump strokes wait 15 minutes before evaluating the indication.|
