Ammonia Measurement in Pure Ethylene

 

The SpectraSensors TDL analyzer is the ideal solution for Ethylene purity applications.

The use of Tunable Diode Laser technology means that analysis results can be updated within seconds. Furthermore, the high resolution that is inherent to the laser eliminates errors due to interferences that have hampered other spectrographic approaches. The non-contact nature of the measurement with no moving parts in the analyzer means it is simple to operate and little routine maintenance is needed. SpectraSensors applies differential spectroscopy where a scrubber specific to ammonia is used to remove the NH3 from the sample and a “zero” background spectrum of the sample is collected. The scrubber is then bypassed and the complete process sample spectrum is collected. The zero spectrum is subtracted from the process spectrum to get a sensitive ammonia measurement free of background gas interferences. The scrubber has a typical lifetime greater than 18 months, and is the only consumable part of the analyzer. In addition to ammonia, trace acetylene and water measurements can be made using TDL technology.
