2.4. Gel Permeation Chromatography (GPC)
Size exclusion chromatography data was collected on a Hewlett-Packard
1260 infinity series instrument equipped with three PLgel 10 \(\mu\)m
mixed-B columns, and a refractive index detector. Polystyrene standards
of molecular weight ranging from 1-200 kg/mol were utilized to calibrate
the instrument. The mobile phase was tetrahydrofuran with a flow rate of
1mL/min. Vegetable oil samples were diluted in tetrahydrofuran to a
concentration of 1mg/mL, then filtered (0.45\(\mu\)m) and analyzed.
