Agilent 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 Manual

Update: 01 October, 2023

A new method for the analysis of trace methanol in crude oil samples was developed based on two-dimensional heart-cutting gas chromatography. The method was tested on an Agilent 6890N GC system equipped with a new gas phase microfluidic Deans switch that improved the performance of heart-cutting two-dimensional gas chromatography. The results obtained with this method exceeded the performance requirements of ASTM D7059 for the analysis of methanol in crude oil.
