Viscotek's complete GPC/SEC systems feature the industry leading Triple/Tetra Detector Array (TDA™) and the GPCmax™, an integrated pump, auto-sampler and degasser specifically designed for GPC/SEC applications.
Triple Detection sets the standard for GPC/SEC technology and is the preferred method for macromolecular characterisation. The TDA™ employs a concentration detector, viscometer and light scattering detector acting in concert, with each detector providing complimentary but different information. The system provides absolute molecular weight without extrapolation or correction, molecular size (Rg and Rh to less than 1 nm), and intrinsic viscosity, as well as information on branching, structure and aggregation in a single GPC/SEC experiment.
A new development in the area of UV-Detection is the addition of a Photodiode array UV detector instead of a single wavelength detector. With a Photodiode array detector full spectral information can be detected at each point of the elution volume.
The GPCmax™ features a variable loop autosampler for reproducible sample injection and an isocratic pump for constant and pulseless solvent flow. It also comes equipped with an in-line solvent degasser to remove dissolved gases and allow optimum performance of concentration, viscosity and light scattering detectors.
RImax - Conventional GPC/SEC-System - robust, inexpensive, easy to use
Gel permeation chromatography with just refractive index (or UV detection)
This conventional GPC system has a single concentration detector, namely a refractive index (RI) or a UV detector. The RImax system has a straightforward design and is therefore robust, inexpensive and easy to use. The system can be upgraded at any time with further detectors.
High Temperature GPC
A complete HT-GPC system for the characterisation of polyolefins, and other synthetic polymers which are soluble only at elevated temperatures. The HT-GPC system provides absolute molecular weight and intrinsic viscosity, as well as information on branching and structure in a single experiment.
Complete product portfolio:
To compliment the GPC/SEC systems we offer a comprehensive range of columns that deliver optimum performance, reliability and long lifetimes, even under the most severe operating conditions. Viscotek also offers a range of GPC standards for natural and synthetic polymer applications.
Viscotek, a Malvern company, is the leading provider of comprehensive Gel Permation Chromatography (GPC) / Size Exclusion Chromatography (SEC) solutions, featuring multiple detection, for the characterisation of natural and synthetic polymers, proteins and nanoparticulate materials. Viscotek's innovative products and technologies are backed throughout the world by superior technical service and analytical support from experienced scientists.
