Water Measurement in Pure Propylene

 
The SpectraSensors’ TDL analyzer is the ideal solution for Propylene purity applications. The use of Tunable Diode Laser technology means that analysis results can be updated every second. Furthermore, the high resolution that is inherent to the laser eliminates errors due to interferences, which have hampered other spectrometric approaches. The non-contact nature of the measurement with no moving parts in the analyzer means that the analyzer is simple to operate and little routine maintenance is needed. SpectraSensors applies differential spectroscopy where the sample is dried using a metal getter technology and the background spectrum of the sample is collected. The dryer is then bypassed and the wet sample spectrum is collected. The dry spectrum is subtracted from the wet spectrum to get a sensitive measurement free of background gas interferences. The dryer has a typical lifetime greater than 18 months, and is the only consumable part of the analyzer.
