Clean-Up with Acetonitrile Eluent (PAE-800) CLNpak PAE-800 was used for GPC clean-up of phthalic acid esters. Compared with the case of analysis with acetone eluent, the saparation of peak 1 and peak 3 to 14 is insufficient. Sample : 1. Corn oil 2. Bis(2-ethylhexyl) adipate 3. Di-2-ethylhexyl phthalate 3-14. Phthalic acid esters 14. Dimethyl phthalate 15. H2O 16. CO2 17. Sulfur Column : Shodex CLNpak PAE-800 (8.0mmID*300mm) Eluent : Acetonitrile Flow rate : 0.5mL/min Column temp. : Room temp.
