AZURA® GPC Cleanup System

Prior to many analysis procedures interfering components in samples must be removed. A manual sample preparation based on Gel Permeation Chromatography (GPC) is customary but also work-intensive and time consuming. Human resources and time can be saved by automation of the GPC Cleanup method with the AZURA® GPC Cleanup System. Through automation, reproducibility and quality of the cleanup and hence the analysis is improved.
