VERITY® GPC Cleanup System with VERITY® 1741 UV-VIS Detector

The VERITY® GPC Cleanup System is an ideal solution for post-extraction cleanup of high-molecular weight interfering substances from environmental samples, food products, and animal tissue prior to analysis using gel permeation chromatography (GPC). Removal of these contaminants leads to more reliable results, fewer sample repeats, and less downtime for downstream chromatography instruments.

VERITY® GPC Cleanup System with optional VERITY® 1741 UV-VIS Detector

GPC Cleanup is a size exclusion cleanup procedure that uses organic solvents for the mobile phase and a specialized column packed with a divinylbenzene-styrene copolymer. The most typical packed phase is BioRad’s Envirobeads® SX-3 resin, packed into a glass column with the mobile phase of interest. Stainless steel and other columns specific for GPC cleanup are also available. GPC cleanup is performed after sample extraction and is thus a post-extraction cleanup method. This method is recommended for the post-extraction elimination of lipids, polymers, copolymers, proteins, natural resins, cellular components, and other high molecular weight compounds from the analytes of interest.

Product Design

The Automated GPC Cleanup Systems are available in two configurations, with and without a VERITY® 1741 UV-VIS Detector. Both systems are configured with a VERITY® 3011 Isocratic Pump with a 10Sc head, a GX-271 Liquid Handler with GX Direct Injection Module and fraction collection valve, a GPC Cleanup Accessory Kit, and TRILUTION® LC software, including GPC methods and instructions.

Fully Automated System Compliant with Government Agency Guidelines

Meets government requirements for GPC cleanup – USEPA, USDA, USFDA, USGS, USDI, Centers for Disease Control (CDC), Canadian Food Inspection Agency (CFIA), European Union (EN 1528, 12393, DFG S19), AOAC International, JIS, GB/T 14552, etc.
