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 behaviour of later sectionsof column or sensors may be modified dynamically during a measurement cycle depending on the readings obtained at the earlier stages. 描述了种在气相色谱分析柱中包括金属氧化物传感器的混合设备，从而来自MOS设备的读数将对样本做出反应而沿着所述柱改变，反映取决于镶嵌所述柱的吸附剂对于各自组份的洗脱效应的、施加于样本的组分上的差分延迟。通过这种手段，获得了系列读数，其中的任意个读数可以针对特定的样本更容易解释，并且其可以在它们之间进行比较，从而提供额外的测量维度。柱或传感器的后续区段的行为可以根据在较早阶段获得的读数在测量循环期间动态地修改。
