Scientex Pty Ltd
has been appointed exclusive distributor for WGE Dr Bures (Germany) GPC/SEC systems and detectors.
WGE Dr Bures designs and manufactures innovative instrument systems for R&D and quality control for macromolecule investigations into bio-polymer, biological and protein analysis and characterisation. Their product range includes the patented SEC 3010 dual detector refractometer/viscometer, a purpose-built refractometer and viscometer unit that combines two separate detectors in a common housing.
The refractometer is an integral component of the viscometer bridge, measuring concentration and viscosity simultaneously on the same sample segment.
The SEC 3010 dual detector refractometer/viscometer provides a factor of 2-5 times higher sensitivity, near zero dead volume and superior performance compared to the more common ‘external’ connection of the two individual detectors.
There is no need to wait for the sample ‘breakthrough’ (the negative signal received after each injection) or to adapt an ‘internal delay’ to the number of size exclusion chromatography columns used with the SEC 3010.
SEC 3010 dual detector refractometer/viscometer can easily handle any GPC/SEC application with any solvent at any temperature up to 80ºC.
