Ammonia (NH3) sorbent traps are used to measure ammonia levels at SCRs/SNCRs to monitor catalyst health and optimize ammonia injection rates. Â
Well developed for engineering purposes, the traps have been used across a wide range of sources and can be used as alternatives to CTM-027 and EPA Method 320.
NH3 sorbent traps provide a low-cost, quick, easy, and effective alternative to FTIR for measuring ammonia concentration.
