Versatile, sensitive and hassle-free trace ammonia analysis
Ammonia (NH3) is a key impurity in many applications, ranging from industrial process control to the analysis of fuel cell hydrogen. Tiger Optics delivers a powerful analytical tool for the measurement of NH3, based on Continuous-Wave Cavity Ring-Down Spectroscopy (CW-CRDS). The HALO 3’s low detection limit, drift-free operation, and compatibility with many different sample gases make it an ideal tool for monitoring trace amounts of ammonia, for example, to ensure compliance with SAE J2719, ISO 14687 or similar purity standards for hydrogen used for fuel cell electric vehicles (FCEVs)*.
Highly specific to the target molecule, CW-CRDS also prevents cross-interferences from distorting your measurement. Plus, there is no need to perform costly and time-consuming zero and span calibrations, saving both time and money with continuous, online service.
Designed for ammonia analysis in laboratory and process applications:
- Accuracy traceable to the world’s major national reference labs
- Industry-proven technology
- Freedom from the need for span calibrations
- No periodic sensor replacement/maintenance
- Sub-part-per-billion (ppb) detection limit
- Wide dynamic range and no drift
*For fuel-cell hydrogen analysis according to ASTM Standard Test Method D7941, the method detection limit (MDL) is 1 ppb, as determined via U.S. EPA 40 CFR Part 136 Appendix B (95% Confidence Limit).
