Surface energy analyser

An image of the surface energy analyserCarbon Nexus' Surface Energy Analyser (SEA) has the ability to evaluate surface energy and wettability of a fibre.

The SEA is an inverse gas chromatography system that determines fibre surface properties by injecting vapour pulses into a column packed with the sample being examined. These vapour pulses elute through the column and the retention time is measured by a flame ionisation detector.

Varying the vapour probe molecule, flow rate, temperature, or column conditions elucidates a wide range of surface and bulk properties of the sample.

Capabilities:

  • Dispersive and polar surface energy measurements
  • Acid/base interactions
  • Micropore and mesopore distributions
  • Surface energy heterogeneity mapping
