GPC

GPC: gel permeation chromatograph

Brand: Perkin Elmer

Software: Empower

Capabilities: Able to measure the molecular weight distribution of polydisperse samples in the range of Mw = 1000 - 1,000,000

Accessory: Refractive index (RI) detector

Practical use: Typically used in the lab to measure changes in the molecular weight of paper samples as they are aged under various conditions (Oxidation from UV light or solvent exposure, hydrolysis from humid aging at elevated temperatures)
