ANALYTICAL SERVICE WORK


Size Exclusion Chromatography

Size Exclusion Chromatography (SEC):

The molecular weight and structure characterization.

As the sample is separated and elutes from the column, it can be characterized by:

  • Conventional Calibration,
  • Universal Calibration,
  • Triple Detection.

Three chromatography systems are available:

 

1- Viscotek HT-GPC:

  • Temperature: up to 160°C,
  • Solvent: 1, 2, 4-Trichlorobenzene,
  • Detectors: RI, Light Scattering (RALS, LALS), Viscometer, UV,
  • Sample type: Polyolefins.
  • Investigations: Mn, Mw, LCB, Polydispersity index “PDI”

  

2- Viscotek TDAmax:

  • Temperature: up to 80°C,
  • Solvent: Tetrahydrofuran, Toluene…
  • Detectors: RI, Light Scattering (RALS, LALS), Viscometer, UV.
  • Sample type: Synthetic polymers, Copolymers.

  

3- EcoSEC/GPC system:

  • Temperature: up to 60°C,
  • Solvent: N,N-Dimethylformamide
  • Detectors: RI, Viscometer, Light Scattering (MALS),UV.
  • Sample type: Synthetic polar polymers.
