Gel Permeation Chromatography

GPC SYSTEM WITH FOUR DETECTORS- DUAL FLOW

Both EcoSEC instruments are compact, all-in-one systems with a dual flow refractive index detector and temperature-controlled interior.

  • The only GPC instrument with a Dual flow cell and distinguished pump design
  • Continuous correction of RI baseline due to solvent instability
  • Improved molar mass precision and accuracy
  • Rapid baseline stability at startup
  • Already equipped with two detectors as RI and UV, and being capable of adding two more detectors as light scattering and viscosity.

The dual-flow design of the RI detector in the EcoSEC GPC Systems compensates for changes in the RI of the solvent over time by continuously pumping fresh solvent through the reference side of the flow cell. This results in superb baseline stability and a decrease in baseline drift.

EcoSec Features & Benefits

  • Compact, low dead volume GPC system
  • Outstanding performance at short analysis times
  • Designed for semi-micro GPC, thereby saving solvent, waste disposal costs and analysis time

Multi-Angle Light Scattering Detector

Multi-Angle Light Scattering detector combines the best of both the MALS and LALS detectors. It offers a conventional cell and an extended flow path that uses 3 angles to provide MALS and LALS analysis.

The LenS 3 detector uses a green laser (λ = 505 nm), which provides approximately 2.7 times higher scattering intensity than a conventional red laser (λ =660 nm). Greater sensitivity is also provided by the unique design of the light path, as opposed to a conventional flow cell, which allows maximum interaction with solute molecules and a more effective light collection mechanism with lower noise.
