and collect clear solution in GC vials. Chromatographic Conditions The GC separation was conducted on an Alltech AT-WAX column with a dimension of 30 meter, 0.53 mm and a film thickness of 1.0 µm. Helium was used as carrier gas at a constant pressure of 4 psi. The GC oven temperature program utilized an initial temperature of 75 °C and
