Equipment: JAI-HPLC LC 9110 II Next
Technique: Gel permeation chromatography (GPC) (Recycling preparative HPLC)
Acquisition year: 2015
Description: Recycling preparative HPLC is a sepration technique that provides a fast and elegant approach to purify mg to gram quantities of starting materials, intermediates and final products. The basic concept is to direct samples post column back to the beginning of the column forming in a closed loop system. With each cycle, the effective column length and resolution increase accordingly. No additional solvents are used during recycling. When the baseline resolution is achieved, samples are collected.
