To prevent poisoning of the catalysts it is essential to check the feedstock contaminants such as Arsine, Phosphine. Da Vinci developed a GC application to determine traces of Arsine, Phosphine & Permanent Gases in Ethylene and Propylene.
The DVLS Impurities Analyzer determines traces of Arsine, Phosphine & Permanent Gases in Ethylene and Propylene.
The typical working range of the permanent gas impurities is low ppmV to 100 ppmV and Arsine/Phosphine is low ppbV to 10 ppmV.
The Impurities in Ethylene/Propylene application is based upon an Agilent Technologies Gas Chromatograph
