All experiments have been performed on a gold substrate. The TPDs have a ramp of 0.2K/s. Since the repulsions on the bond pairs in H2O molecule are greater than that in NH3 the bond angle in water is less than that of ammonia. The Axetris LGD F200P2-H NH3/H2O laser gas detection OEM module detects ammonia down to the sub-ppm range, ensuring stable processes. charges on CH4, NH3, H20, and H2 (5-7).
