we are using ordinary yellow chart paper to detect ammonia leakage spots in pipe lines and joints.  The color of the yellow chart paper piece turns pink when ammonia is leaking.  this even detects leakages which cannot be detected by bubble test (even with reputed brand leak finders) or by any toxic leakage detectors.  Kindly explain how this happens?
