KOPTRI provides GPC (Gel Permeation Chromatography) service with THF (Tetrahydrofuran), one of the most commonly and widely used organic solvent for the GPC-setup.

Acrylic and Styrenic polymers, along with most of the polymers, are soluble in THF. Since these polymers have low molecular weight (few hundred) to high molecular weight (few million) in range, an adequate GPC column should be used to analyze. Our institute has a variety of GPC columns with low to high molecular weight range, and utilizes appropriate column for the target polymer to produce reliable molecular weight measurements. For example, measuring polymers with adsorptive functional groups are analyzed by adding suitable additives in the GPC eluent to reduce the adsorption or using a column that could minimize adsorption. Our institute has more than 20 years of experiences in measuring the molecular weight of various unusual types of polymers manufactured worldwide. With the expertise and technology, we could provide the finest GPC solutions, so please consult with our institute for GPC analysis of unique polymer structure. If you need help with analysis, please send us a request by submitting ‘Application Form’ under ‘Contact Us’ tab, and supervising researcher will aid you with a punctual and meticulous reply.
