SEC-3010 COPO
Sometimes, even when conventional gel permeation chromatography GPC/SEC is used and all calculations are based on a conventional column calibration, a single refractometer is not sufficient. A second concentration detector is required, to detect impurities for example, or to calculate co-monomer content of a co-polymer.
These are the playgrounds for the SEC-3010 COPO system. Two concentration detectors, our refractometer and our multi-wavelength UV detector, build together with pump, autosampler and ParSEC Standard the system of choice.
And yes, you may add a viscometer or SLS detector later if necessary.
