Abstract: A thermal conductivity detector device includes a chamber defined with an inlet channel and an outlet channel. A temperature sensing element is positioned proximal to the outlet channel and a plurality of passages is defined between the inlet channel and the outlet channel. The plurality of passages is structured to direct a fluid from the inlet channel to impinge on the temperature sensing element to detect the temperature of the fluid.

Abstract: A thermal conductivity detector device includes a chamber defining an inlet channel and an outlet channel. A temperature sensing element is positioned proximal to the outlet channel to detect temperature of a fluid flowing through the chamber from the inlet channel to the outlet channel. The temperature sensing element includes a body defined in a cylindrical shape with a through passage and, the through passage defines an inner surface for the flow of a fluid.

Abstract: A thermal conductivity detector device includes a chamber defined with an inlet channel and an outlet channel. The chamber is of an elliptical shape having at least two opposing sides of the chamber defined in an arcuate shape. The chamber is defined in the shape of a venturi. A temperature sensing element is positioned within the chamber. The temperature sensing element is configured to determine the temperature of a fluid flowing through the chamber from the inlet channel towards the outlet channel.
