Available from Viscotek (www.viscotek.com) is a new Tetra Detector system that opens the way to in-depth characterisation of complex molecules including copolymers and PEGylated proteins.

The Tetra Detector harnesses the power of RI, viscometry, UV and light scattering detectors acting together, with each detector providing complimentary but different information. Maintained in a thermostatically controlled environment the new Tetra Detector has the sensitivity and stability to repeatably characterise polymers and proteins even at low concentrations. In a single experiment, the Tetra Detector enables users to obtain molecular weight, molecular size, intrinsic viscosity, conformation, structure, branching, aggregation and copolymer data from their sample.

Data from all 4 detectors is collected and processed seamlessly in OmniSEC software. The software can take concentration data from the RI, UV or both detectors. When used simultaneously, the proprietary OmniSEC copolymer software uses both RI and UV signals to obtain the correct concentration; enabling precise determination of the composition of synthetic copolymers and PEGylated proteins.
