miniDAWN® TREOS® II Multi-Angle Light Scattering Detector

The Best in Basic Multi-Angle Light Scattering for Absolute Macromolecular Analysis

The miniDAWN® TREOS® II determines absolute molar mass and size to characterize proteins, peptides, small polymers and nanoparticles in solution. Coupled to size exclusion chromatography (SEC or GPC), it eliminates the uncertainty and hassle of column calibration, for true confidence in macromolecular characterization.The TREOS II not only offers superb sensitivity—it further enhances productivity thanks to some unique capabilities: field serviceability, upgradeability to UHPLC and One-Click Mw™.

The key feature of mini DAWN TREOS II is Upgradeability to UHPLC. If the users decides to transition to UHPLC, the standard HPLC optical module can be replaced with a UHPLC-compatible, micro-flowcell optical module*.

  • MW from 200 Da to 10 MDa.
  • Sensitivity : 25 ng of 100 kDa polystyrene in THF.
  • rgfrom 10 to 50 nm, upto 150 nm with shape specific models.
  • Ultra-stable laser.
  • Compatible with any HPLC system.
  • High signal-to-noise ratio, low-stray-light flow cell.
  • Wide measurement range for particles up to 50 nm in radius.

Simplicity personified

Sample-specific methods are set up in three short steps with ASTRA's Method Wizard, and new capabilities for automatic data processing mean that it takes just one click from your sample to a full report of the molecular weight and size results.

The TREOS II's System Ready monitor will even let you know when the system is fully equilibrated with low baseline noise, ready to run.
