We report the fabrication of a gas chromatographic column module integrated on a silicon
substrate and usable as a portable measurement device dedicated to the selective detection …

Over 30 years, portable systems for fast and reliable gas analysis are at the core of both
academic and industrial research. Miniaturized systems can be helpful in several domains …

Indoor air quality monitoring applications require both high sensitivity and selectivity, which
are difficult to reach with solid state gas sensors. While for some gas species like, eg CO and …

A small column (micro-column) has been fabricated on-chip that can contribute to
development of a miniature gas Chromatograph for mobile and multi-point atmospheric …

The discrimination of various chemical compounds is generally impossible by using a single
tin dioxide-based gas sensor. This research is focused on the development of a hybrid micro …

This paper reports a full micro gas chromatograph (µGC) in which all the components are
electronic. All components, including a Knudsen pump, a preconcentrator, separation …

This paper presents the implementation for the first time of a porous SiOCH thin layer as
stationary phase for silicon microcolumns for gas chromatography (GC). Deposition of the …

Many microfabricated gas chromatography (micro-GC) column designs have been reported
so far, but it is unclear how microcolumn design affects separation performance in the typical …

This research concentrates on the sensitivity of a tin dioxide-based gas sensor
semiconductor with respect to hydrogen fluoride in the atmosphere. This paper is focused on …

Since the late 1970s, approaches have been proposed to replace conventional gas
chromatography apparatus with silicon-based microfabricated separation systems …
