The TDAmax consists of three components – the GPCmax integrated solvent and sample delivery module, the TDA 305 Triple Detector Array, and the OmniSEC software. The TDA 305 incorporates RI and, Light Scattering detectors, as well as a viscometer and optional UV detector. Both the integrated detectors and the chromatography columns are fully temperature controlled in an oven to ensure optimum detector stability. In addition, the detectors are connected in series to ensure maximum sensitivity.

  • Absolute molecular weight of small polymers, protein stability and protein aggregation using Right angle light scattering (RALS)
  • Direct output of absolute molecular weight of polymers without extrapolation using Low angle light scattering (LALS)
  • Protein and polymer structure (including branching) information using intrinsic viscosity detector
  • Molecular size in terms of hydrodynamic diameter (Rh) and the radius of gyration (Rg)
  • Copolymer composition using photo-diode array UV detector
  • Autosampler incorporated to increase throughput and improve repeatability
  • Advanced GPC/SEC software capable of going from data to results in just two clicks
  • 3D absorption plot for chemical identification of each component
  • 21 CFR part 11 compliant
  • Full suite of calibration and GPC/SEC calculation types
