Surface Characterization

The determination of the surface plays an important role for many applications. The surface area as well as the kind and magnitude of specific interactions are crucial parameters for the usability of materials.

We provide customers worldwide with the following state-of-the-art surface related characterization methods:

• surface area:
  BET-surface area (dynamic) • BET-surface area (static) • micropore surface area • data treatment via NLDFT-method • mercury intrusion porosimetry • inverse size exclusion chromatography • determination of active surface area via TPR

• homogeneity of the surface:
  TEM/EDX • SEM

• specific surface interactions:
  temperature-programmed desorption (TPD) • temperature-programmed reduction (TPR) • temperature-programmed oxidation (TPO) • chemisorption • adsorption isotherms via frontal analysis • adsorption isotherms via pulse-sorption • thermogravimetry (TG/DTA) • nuclear magnatic resonance (NMR) • infrared spectroscopy (IR) • elemental analysis (EA) • LC methods
