Use of oxide ceramic nanolayers of organic dispersions as highly efficient separation media for gas chromatography
Gas chromatography is the main method for quantifying gases and volatile compounds (e.g. hydrocarbons from natural gas). In a chromatographic analysis the various components of the sample are separated in capillaries before detection. The separation happens on special surfaces, which are modified for the respective tasks. Aim of the project is the use of layers from oxide ceramic nano-particles (such as aluminium oxide) as a novel separation media. As nanoparticles have a very large surface area in comparison to their mass, very high separation capacities are expected on the nano layers formed. The improved separation capacities facilitate shorter and more accurate analyses of samples from industry and the environment.
Sub-projects of IEK-8: coating of capillary columns with nanoparticles
The project is funded by the BMBF within the SME innovation offensive "NanoChance" (nano_initiative_action_plan_2010.pdf)
