NotesThe hydrocarbon mix was first analyzed to generate a baseline reference; then, ten separate 10 μL injections of water were made 1 minute apart using the same method. After the final water injection, the hydrocarbon mix was analyzed again to compare the chromatography before and after the water injections.
