UV Detectors provide unsurpassed sensitivity and selectivity as concentration detectors in GPC/SEC. The only limitation is that the sample must contain chromophoric groups and that the solvent used provide a window in the absorption range of UV light. With these conditions fulfilled, a UV Detector is of great use as a single concentration detector in GPC/SEC or, combined with a DRI Detector, for the determination of composition distribution of copolymers.
The AYE Rapid Scanning UV combines high sensitivity, a huge linear range of more that 4 orders of magnitude and flexibility in the application, with solid physical base of clearly defined band- width and wavelength precision. It allows detection at two wavelengths, optional four wavelengths, at the same time and is therefore best suited for application where complex copolymers need to be characterized.
