How does separation work in Gel Permeation Chromatography?
 
Tetra Detector Array
A revolutionary, integrated multiple-detector device designed for the characterization of natural and synthetic polymers and copolymers, proteins, protein conjugates, excipients and other macromolecules. Comprised of modular Refractive Index, Ultra-Violet, Low Angle Light Scattering and Viscometer detectors.
 
Application Notes
Our database of GPC/SEC application notes explain the use of concentration, viscometer and light scattering detectors to obtain a distribution of absolute molecular weight, size and intrinsic viscosity, as well as information on conformation, aggregation, branching and copolymer composition.

About Viscotek
Viscotek HQ HoustonViscotek Corporation, headquartered in Houston, Texas, was founded in 1984 by Dr. Max Haney, the inventor of the four capillary differential viscometer detector. Since its inception, Viscotek has pioneered innovative technologies and products for the characterization of natural and synthetic polymers, biopolymers and nanoparticles.

This pioneering spirit has allowed us to become a market leader in the manufacture of Gel Permeation Chromatography (GPC), Dilute Solution Viscosity (DSV) and Dynamic Light Scattering (DLS) detectors, software and systems for macromolecular characterization.

Known for its commitment to quality and innovation, Viscotek continuously works towards better solutions by improving current instrumentation and developing new products and applications. Our goal is to provide the appropriate analytical instruments, techniques and approach for your characterization and measurement requirements.

Four Capillary ViscometerViscotek takes pride in being the only manufacturer capable of supplying complete solutions for GPC, DSV and DLS applications. "The solutions we provide are comprehensive," says Dr. Haney. "That is what differentiates Viscotek in the GPC, DSV and DLS markets. Our patented detectors, proprietary software and product offering provide our clients with a full range of opportunities, while our technical expertise and support allow us to turn these possibilities into reality."

Operating out of the corporate offices in Houston, Texas, Viscotek USA provides coverage for all 50 states, Canada and Mexico. Viscotek Europe, headquartered in the UK with offices in the Netherlands, France and Germany, has responsibility for sales and service in the European market. By coupling our offices with an extensive international distributor network, Viscotek has become a truly a global company providing worldwide coverage and support.
Complete Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) systems for the characterization of natural and synthetic polymers, proteins, conjugates and excipients. Integrated Triple and Tetra Detector Arrays (TDAs) featuring Low Angle Light Scattering (LALS) detectors, four capillary differential viscometer detectors, refractometers and UV/VIS detectors; in a single experiment, obtain absolute molecular weight, molecular size, intrinsic viscosity, conformation, branching, aggregation and copolymer composition. Flow Injection Polymer Analysis (FIPA) for fast, accurate and precise average molecular weight, size and intrinsic viscosity in routine QA/QC and process control. Automated Dilute Solution Viscosity (DSV) systems provide relative, inherent, and intrinsic viscosity.
