All PSS light scattering detectors are seamlessly integrated in the PSS WinGPC UniChrom software and can be used in a stand-alone setup or in a client/server network environment. A WinGPC software wizard allows both, a simple, secure and fast detector setup including inter detector delay determination and detector calibration, as well as a regular verification. The wizard automatically adjusts to the type of detector (LALLS, RALLS, TALLS, MALLS). Comfortable sequence and WinGPC end actions for the detectors protect investments, save resources and extend the lifetime of lasers and laser diodes.
