Abstract: A hybrid device comprising Metal Oxide Sensors in a Gas Chromatography column is described, whereby the readings from the MOS devices will vary along the column in reaction to the sample reflecting the differential delays imposed on the components of the sample depending on the elutive effect of the adsorbent lining the column for the respective component. By this means, a family of readings is obtained, any one of which may be easier to interpret for a particular sample, and which may be compared amongst themselves providing an additional measurement dimension. The behavior of later sections of column or sensors may be modified dynamically during a measurement cycle depending on the readings obtained at the earlier stages.
