Setting standards for polymer and protein characterisation

The SEC-3010 triple detector system from UK-based Dorton Analytical is a complete chromatography/size exclusion chromatography (GPC/SEC) system.

The SEC-3010 triple detector system from UK-based Dorton Analytical is a complete chromatography/size exclusion chromatography (GPC/SEC) system comprising pump, autosampler, viscosity/refractive index detector, multi-angle light scattering detector and ParSEC enhanced software. The patented design of the SEC-3010 viscosity/refractive index detector allows the simultaneous determination of the refractive index and the intrinsic viscosity of a polymer solution.

The Thame, Oxfordshire-based firm says the sophisticated technology of the device overcomes the disadvantages usually encountered with coupled detectors. The asymmetrical bridge circuit allows 80% of the sample to reach the measuring arm, compared with 50% in conventional instruments, thus increasing sensitivity by a factor of 2, the
