MICRO-THERMAL CONDUCTIVITY DETECTOR, METHOD TO FABRICATE SUCH AND CHROMATOGRAPHY SYSTEM USING SUCH

摘要

A heat flux sensor, a micro-scale gas chromatograph comprising the heat flux sensor, and method for measuring the thermal conductivity of a fluid using such are provided. The heat flux sensor comprises a chamber, a heating element suspended in the chamber, at least two current contacts configured to exchange a current with the heating element, and at least two measurement contacts configured to measure a voltage change along the heating element indicative of the thermal conductivity of the fluid.
