Requires free registration and login Application communication: Determination of polymer structure by GPC
It is advantageous to use light scattering to determine molecular weights provided the signals are sufficiently intensive strong. Triple detection combines these detection capabilities into a single system to give molecular weight and structure without limitations.

Requires free registration and loginApplication communication: Characterization of branched copolymers by triple detection GPC
Polymers can be loosely grouped into two structural categories – linear and branched. A linear polymer is composed of a single main chain of repeating units, linked in a regular end to tail fashion.

Requires free registration and loginApplication communication: Characterization of modified phenolic resins
The triple detection chromatography technique was shown to be able to detect the modification of the phenolic resins. The high molecular weight is easily revealed in the light scattering signal while the viscometer gives information on the partial molar volume occupied by the polymer.
