HPLC Method for Analysis of Poly(propylene glycol) bis(2-aminopropyl ether) on Zodiac HST- OG2 Column

Description

Poly(propylene glycol) bis(2-aminopropyl ether) is a diamine-terminated polyether used in polymer synthesis and epoxy curing. It can be effectively retained and analyzed using the Zodiac HST OG2 mixed-mode column under gradient conditions with acetonitrile, water, and trifluoroacetic acid (TFA) as the mobile phase. Detection is performed using ELSD at 50°C, ensuring reliable separation of polymer variants based on molecular weight distribution.
