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.

Features
  • 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

Typical Applications
  • 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
