Viscotek, the leader in multiple detection characterisation of synthetic and natural polymers, has announced a new UV detector option extending the versatility of its market leading Triple Detector Array (TDA™) system.

The TDA™ employs a concentration detector, viscometer and light scattering detector
acting in concert, with each detector providing complimentary but different information. In a single experiment, the TDA™ enables users to obtain molecular weight, molecular size, intrinsic viscosity, conformation, structure, branching, aggregation and copolymer data from their sample.

The TDA™ now combines the power of traditional triple detection
with new programmable wavelength UV detection (190-360nm). Maintained in a thermostatically controlled environment the new TDA UV detector has the sensitivity and stability to repeatably characterise proteins at low concentrations.

Data from the TDA™ UV detector is collected along with other detector signals 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
