The fabrication of glass chips for capillary electrophoresis by means of micromachining is reported. The device is made up of two glass substrates joined by means of thermal fusion bonding. Selective wet etchings were used to define five microchannels, four for samples injection and one for the separation, while the access holes were obtained with diamond drills. Good results in terms of process quality have been obtained.

Abstract
The fabrication of glass chips for capillary electrophoresis by means of micromachining is reported. The device is made up of two glass substrates joined by means of thermal fusion bonding. Selective wet etchings were used to define five microchannels, four for samples injection and one for the separation, while the access holes were obtained with diamond drills. Good results in terms of process quality have been obtained.File in questo prodotto:
