Ammonia Sorbent Traps
Simple, cost-effective alternative to FTIR
Ammonia (NH3) sorbent traps are used to measure ammonia levels at SCRs/SNCRs to monitor catalyst health and optimize ammonia injection rates.
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.
Sampled using the same equipment as Method 30B Hg traps
Option to perform analysis on-site using an ion chromatograph for immediate results or send to Ohio Lumex for lab analysis
Use in conjunction with Hg speciation traps or 915J Real-Time Hg Monitor to quantify the relationship between NH3 concentration and Hg oxidation
High sensitivity produces accurate results even at low levels-MDL below 0.1 ppmv
Use to check the performance of other analytical instrumentation and methods
Precision verified by excellent paired agreement between sorbent traps
Quickly spot-check ammonia slip at any time
Measuring ammonia slip through the SCR/SNCR
Measuring ammonia between layers of the SCR to monitor catalyst layer performance.
Tying ammonia slip to catalyst health - particularly as it applies to mercury oxidation efficiency in the last layer of the SCR
