Product Description

  • All-in-one GPC system with RI and UV detectors
  • Operates in temperatures ranging from ambient to 60 °C
  • Delivers superior performance and unmatched baseline stability resulting from the unique dual flow RI detector design.
  • The degree of precision in retention time and molar mass determination far exceeds the market standard due to its advanced temperature controlled pumps and the overall thermal stability of the entire system.
  • This high level of engineering results in baselines that stabilize within 90 minutes, exhibit less noise and drift, and deliver exceptional reproducibility day to day, system to system, and site to site.
  • The inherent low dead volume of the EcoSEC GPC System with RI and UV Detectors allows for the use of advanced 15 cm semi-micro columns, which drastically increase throughput and decrease solvent usage, saving you time and money.
