In this work, the performances of a Cr-doped WO3 sensor array are investigated for the application of this device as detector in gas chromatographic systems. Chromatographic separation modules combined with detectors based on semiconducting metal oxides enable the implementation of systems with both high selectivity and high sensitivity. Comparison of results of the sensor array and mass spectrometer...
This work presents the design, fabrication and characterization of a Si-based microseparation module for liquid chromatography (LC), targeted for agrofood applications and in particular for wine quality monitoring. The microsystem chip is a Silicon/Pyrex structure realized by anodic bonding. The basic Si-chip modules are an open tubular microcolumn with inlet/outlet for fluidic connections, a platinum...
