ELSD 7 Angles SLD7000
The SECcurity SLD7000 MALLS (MALS) is a 7-angle static light scattering detector for the measurement of absolute molecular weight, size, and conformation of macromolecules in solution. The revolutionary design with a cylindrical, self-cleaning, and index-matching cell avoids common pitfalls in GPC/SEC-light scattering detection. Modern ultra-sensitive CCD detection results in high sensitivity, even at low concentration and molar masses.
The small footprint allows integration into any GPC/SEC or FFF system. The SLD7000 can be used in batch mode (off-line) without modifications. In combination with an RI and a viscosity detector the light scattering detector can be used for triple detection and triple plus detection.
