Molecular Weight Analyzers

Multi angle detector for the use within laboratories where molecuar weight, the radius of gyration and the second virial coefficient are determined according to the Zimm Plot method. Another field of application is the use as a multi angle light scattering detector for GPC/SEC. In connection with Windows-Software the detector is usable as USB-interface for other modules such as concentration detectors and the injector.

The BI-MwA Molecular Weight Analyzer is simple to use, but incorporates sophisticated features. Inject your sample into the low-volume, 7-angle flow cell. The sample is illuminated by a temperature stabilized, precision power-controlled diode laser. The ultra-stable, high-sensitivity, low-noise CCD detector automatically collects the scattered light. Then, the software extrapolates the data to zero angle for the absolute molecular weight determination. 

Features at a glance :

  • Multiangle, laser light scattering detector for SEC/GPC or stand alone use
  • Proteins & polymersPolysaccharides & biopolymers
  • Polysaccharides & biopolymers
  • Study protein aggregation, oligomerization, & complex formation
  • Mn, Mw, Mz, Rg, A2
  • Small footprint, stackable
  • RI and Viscosity detectors optional

The Brookhaven 200SM Goniometer is a high precision tool for research and development for both static and dynamic light scattering. Measurement of static light scattering (SLS) yields valuable information about properties of particles and macro molecules, dynamic light scattering (DLS) about hydrodynamic size. The BI-200SM is assembled from modular components and thus can be tailored to individual needs from a selection of different lasers, optical components, detectors including cross correlation and other accessories. Including special scientific software package.

Features at a glance :

  • Stepping motor controlled, multi angle measurements
  • Particle size and size distributions
  • Mw, Rg, A2 for dilute polymer solutions
  • Cross-correlation detector option
  • Avalanche photodiode detector option
  • CONTIN, Zimm, Guinier, Fractal, and more

The new 90 Plus Particle Size Analyzer incorporates all you need for fast, routine, sub micron measurements. Based on the principles of Dynamic Light Scattering (DLS), most measurements only take a minute or two. Choose from the standard 35 mW laser for strong scatters, or the avalanche photo diode for weak scatters. And, at the time of manufacture, or as a future upgrade, add the BI-Zeta option for zeta potential measurements.

Features at a glance :

  • Rapid and accurate particle size distributions
  • Multimodal & unimodal size distribution software
  • Range < 1 nm to 6 µm
  • Easy to use Windows™ software
  • Customizable reports, SPC charts
  • Ideal for fast, routine sizing applications in research or quality control
  • High power 35 mW diode laser
  • Dynamic light scattering at 90° and 15°
  • Compact bench top unit
  • Optional zeta potential modules available
  • Foqels module for sizing in concentrates available
