Equipment

.

ICS-900 (Dionex)
  • Ionic chromatography
  • Anions and cations separation and dosage quantitative .
Spectraa 220FS (Varian)
  • Spectroscopy atomic absorption
  • Analysis of a majority metallic cations
Wyatt Technologie (Wyatt)

- Gel Permeation Chromatography (G.P.C.) (polymers in solution characterization). This equipment allows to determine the following macromolecular sizes :

  • increment of refractive index (dn/dc)
  • the absolute molar mass
  • and size of the polymers

- Dynamic characterization of membranes :

  • determining pore sizes and threshold power cut by the measure of the retention of polymers.
  • separation and dosage of polymers.
