Gel permeation chromatography coupled with fourier transform infra-red spectroscopy is a very powerful technique for polymer characterisation
Gel permeation chromatography coupled with fourier transform infra-red spectroscopy is a very powerful technique for polymer characterisation, providing compositional information as a function of molecular weight.
It is particularly useful for the analysis of copolymers and polymer blends plus polymer additives, as well as conformational changes in polymers, eg short chain branching in polyethylene.
Polymer Laboratories, specialist in GPC, offers a GPC-FTIR interface for direct coupling of these two analytical techniques in continuous flow mode.
The uniquely designed flow cell, which slots directly onto the optical bench of the spectrometer, features low dispersion for minimum band broadening and is available with a choice of window materials. The cell assembly can operate at ambient temperature or be controlled up to 175C, which, together with the heated transfer line supplied with the interface, facilitates both ambient and high temperature GPC applications.
The interface is compatible with any GPC system and most industry standard FTIR spectrometers.
