Functionalized Metal Oxides As A Stationary Phase And A Surface Template For Micro Gas Chromatography Separation Columns

摘要

The present invention provides a detector and method for detecting substances in complex mixtures. The detector includes a microfabricated preconcentrator, a separation column with an on-chip thermal conductivity detector, a controller for controlling flow and thermal management and a user interface. The thermal conductivity detector includes a first resistor located at an inlet of the separation column and a second resistor located at an outlet of the separation column.
