Parallel Processing for GPC Sample Clean-up

Gel Permeation Chromatography is a well-known technology for the removal of fats, proteins, and other large bio-molecules from samples in order to prevent interference in the analysis of chlorinated hydrocarbon pesticides, PCBs, antibiotics, mycotoxins, polyaromatic hydrocarbons (PAH), and other semi-volatile compounds.

The GPC Quattro technology can be used for the clean-up of complex animal tissues, food products, and environmental samples. The high recoveries and concentrated samples are easily analyzed by GC, GC-MS, HPLC or LC-MS.

Ideally suited for high-throughput laboratories requiring reliability and reproducibility, the GPC Quattro is designed for 4x the productivity of a single column system. Engineered for robustness and low maintenance, the GPC Quattro provides the ease of use necessary for increased throughput and worry-free operations.
