Clean-Up with Acetone Eluent (PAE-800 AC) CLNpak PAE-800 AC was used for GPC clean-up of phthalic acid esters. Compared with the case of analysis with acetonitrile eluent, the saparation of peak 1 and peak 3 to 14 is better. 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 AC (8.0mmID*300mm) Eluent : Acetone Flow rate : 0.5mL/min Column temp. : Room temp.
