Abstract
A method for dilinoleic acid extraction and elution that includes the steps of pipetting aviation fuel into a first syringe barrel with a filter; allowing the aviation fuel to flow through the filter into a waste collection vial; pressing on a inserted first syringe plunger such that any remaining volume of fuel is expelled through the filter and into the waste collection vial; removing excess fuel from the filter; affixing the filter to a second syringe barrel; pipetting a polar organic solvent into the second syringe barrel and allowing the polar organic solvent to flow through the filter into a sample collection vial; expelling remaining volume of the polar organic solvent through the filter and into the sample collection vial; homogenizing contents of the sample collection vial; and, measuring concentration of dilinoleic acid in the volume in the sample collection vial.
