Benzalkonium Chloride (1) (GF-310 HQ)

Benzalkonium chloride was analyzed using Asahipak GF-310 HQ (an Aqueous/Organic (multi-solvent use) SEC column). Since benzalkonium chloride has benzene ring in the molecule, it can be detected by a UV detector better than by an RI detector.

Sample : Benzalkonium chloride 0.2%, 20μL



Column : Shodex Asahipak GF-310 HQ (7.5mmI.D. x 300mm)
Eluent : CH3CN/50mM NaCl aq.=50/50
Flow rate : 0.6mL/min
Detector : UV(220nm), Shodex RI
Column temp. : 40°C
