TDAmax - Advanced GPC/SEC System for Macromolecular Characterisation
Viscotek Triple Detector Array System (viscosity detector, low angle light scattering detector, refractive index detector and UV detector as an option)

This GPC/SEC systems feature the industry leading Triple/Tetra Detector Array (TDA™) and the GPCmax™, an integrated pump, auto-sampler and degasser designed for GPC/SEC applications.
Triple Detection sets the standard for GPC/SEC 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 is the addition of a Photodiode array UV detector instead of a single wavelength detector which gives full spectral information each point of the elution volume.
The GPCmax™ features a variable loop autosampler and an isocratic pump. It comes equipped with an in-line solvent degasser to remove dissolved gases and allow optimum performance of concentration, viscosity and light scattering detectors.

RImax - GPC/SEC-System - robust, inexpensive, easy to use
This conventional GPC system has a single concentration detector, namely a refractive index (RI) or a UV detector.

High Temperature GPC
for the characterisation of polyolefins and other synthetic polymers which are soluble only at elevated temperature.
