Accurate measurement of the polymer or protein concentration profile is essential for good molecular weight or structure data.
The high-sensitivity RI in the TDA has been designed specifically with multi-detection GPC/SEC in mind. It features a high power light source for maximum sensitivity and stability. The light source is wavelength-matched with the LALS detector to give accurate determination of molecular weight and the specific refractive index increment (dn/dc).
The RI detector can be automatically purged from the software or as part of a programmed sample sequence and the carefully designed purging system eliminates major temperature changes, giving rapid baseline recovery.
The unique design allows the detector to be in series between the light scattering and viscometer detectors. This is the only configuration which gives maximum signals on all detectors in a multi-detector GPC/SEC system.
