Ammonia Test Strips for Industrial Coolants – Pacific Sentry

If the sensor color response indicates a high-level ammonia, ppm NH3 or above, be aware that this is the upper end of its indicator range. The ammonia in solution may be of a higher concentration, possibly much higher, exceeding the strips limit so it cannot show that, however, the sample can be diluted and retested to determine the ammonia level if necessary.

Highly sensitive and chemically stable NH3 sensors based ...

The CA/PEGDA sensor can clearly distinguish between exhaled breath with an additional ppm NH 3 and normal exhaled human breath. However, there is a gap between the analytical method used in this work and the real exhaled breath analysis method, which is very complicated. Thus, this test can prove that ammonia at the sub-ppm level can be detected in the complex environment of exhaled breath ...
