Using a New Gas Phase Micro-Fluidic Deans Switch for the 2-D GC Analysis of Trace Methanol In Crude Oil by ASTM Method D7059

Abstract: A new ASTM method has been developed for the analysis of trace methanol in crude oil samples. This method relies on the use of two-dimensional heart-cutting gas chromatography to separate methanol from the complex matrix. A new microfluidic Deans switch has been developed for the Agilent 6890N GC system that improves the performance of heart-cutting 2-D gas chromatography. This system was used to perform the analysis of methanol in crude oil with results that exceed the performance requirements of the ASTM method.
