Clean-Up with Acetonitrile Eluent (PAE-2000)


CLNpak PAE-2000 was used for GPC clean-up of phthalic acid esters. Please compare with the case of analysis using PAE-800 and analysis with acetone eluent.

Sample : 1mL, dissolved in acetonitrile
1. Corn oil
2. Butylbenzyl phthalate
3. H2O
4. Sulfur
5-16. Phthalic acid esters
5. Di-ethylhexyl phthalate, 6. Di-n-octyl phthalate, 7. Di-heptyl phthalate, 8. Di-n-hexyl phthalate,
9. Di-pentyhl phthalate, 10. Di-isobutyl phthalate, 11. Di-n-butyl phthalate, 12. Di-n-propyl phthalate,
13. Di-cyclohexyl phthalate, 14. Butylbenzyl phthalate, 15. Di-ethyl phthalate, 16. Di-methyl phthalate
