The RImax is a modular system consisting of the GPCmax integrated solvent and sample delivery module, refractive index detector, column oven, plus the same powerful OmniSEC software used in the TDAmax research system.

  • Relative molecular weight measurement and molecular weight distribution of polymers and proteins
  • Autosampler incorporated to increase throughput and improve repeatability
  • In line degasser and automatic eluent sensor for out of solvent warning
  • Column oven to give repeatable elution profiles
  • Advanced GPC/SEC software capable of going from data to results in just two clicks
  • Upgradable to add light scattering (RALS and LALS) intrinsic viscosity and UV detectors, to provide absolute molecular weight, molecular size, structure and composition of proteins and polymers

The GPCmax contains an integrated pump, autosampler and degasser. Mobile phase, stored in solvent bottles placed on top of the instrument, enters the dual piston pump after passing through the eluent sensor. This will automatically stop the flow if the solvent is exhausted mid-run. An inline degasser then removes dissolved gases from the mobile phase, which improves the baseline on any of the detectors that may be connected. The pump is compatible with any solvent, even acidic buffers.

The autosampler inside the GPCmax can hold up to 120 vials, which can either be heated, or cooled to prevent degradation of the samples over time. The Autosampler provides the system with variable, reliable, accurate and reproducible injection volumes, enabling comprehensive macromolecular characterizations to be made with confidence.

Mobile phase (and sample) passes through the GPC/SEC chromatography columns in the column oven. After eluting from the column, the dissolved polymer molecules are now separated by size and pass through the RI detector before going to waste.

A complete GPC/SEC system to provide a conventional, calibration system for relative molecular weight measurement.
