GPC Clean-up of Phthalic Acid Esters = Clean-up with Acetonitorile Eluent (PAE-800)

Clean-up with Acetonitorile 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.
