Ammonia Sorbent Traps

Simple, cost-effective alternative to FTIR

Available for Download

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.

Product Details

Ammonia Sorbent Traps 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 for Ammonia Sorbent Traps

  • 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 – particular as it applies to mercury oxidation efficiency in the last layer of the SCR
