Buyer?s MGuide Analysis Oxygenates in gasoline. Agilent Technologies announces equipment and procedure improvements for the American Society for Testing and Materials method D4815 for analyzing for oxygenates in gasoline. Backflush time is faster, which is critical to avoiding loss of oxygenates and eliminating interferences, and a new trap column design gives better temperature control and reduces the backflush time range.
