Porous silicon based microdevice for reversed phase liquid chromatography
Abstract
This paper deals with On-Chip-Chromatography separation systems micromachined on porous silicon. Reversed phase C18 was prepared on the porous silicon base and characterised by means of FTIR and water contact angle measurements. From this preliminary study, a liquid chromatography microdevice including silanised porous silicon layer was realized and tested for the separation of model mixture of dimethyl- and dioctyl phthalates.
