Simultaneous Analysis of Trace Oxygenates and Hydrocarbons in Ethylene Feedstocks Using Agilent 7890B GC Capillary Flow Technology 
The Agilent 7890B gas chromatograph Capillary Flow Technology, combined with enhanced electronic pneumatics control (EPC), provides greater productivity and flexibility in the analysis of trace contaminants in ethylene. Multiple auxiliary EPC channels provide the ability to automatically generate gas calibration standards for trace level impurities. Enhancement of ASTM D6159 method with 2-D GC Deans switching measures trace oxygenates and hydrocarbons in a single run. The ASTM Method D6159 uses a methyl silicon column in series with an alumina PLOT column to resolve light hydrocarbons in ethylene. The Agilent 7890B GC serves as the ideal platform when analyzing different classes of trace compounds in ethylene. View application note
