PSS - Model SLD7100 MALLS -Multi Angle Static Light Scattering Detector
The SLD7100 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.

7-angle MALLS instrument suitable
- for batch MALLS analysis
- as GPC/SEC/GFC detector
- as FFF detector
The small footprint allows integration into any GPC/SEC or FFF system. In combination with an RI and a viscosity detector the light scattering detector can be used for triple detection and triple plus detection.
The SLD7100 can be used in batch mode without modifications.
- 7 angle static light scattering detector for the simultaneous detection of the time-averaged scattering intensity at 7 different detection angles (35°, 50°, 75°, 90°, 105°, 130° and 145°).
- Self cleaning, index-matching PEEK cell with vertical flow path and fibre optics with low numerical aperture, integral to cell.
