Abstract: A Thermal Conductivity Detector (TCD) based Gas Chromatography (GC) device includes a TCD oven formed by a plurality of walls and has an inlet valve and an one outlet valve; a TCD element housed in the TCD oven; a heating source mounted on any one of the plurality of walls of the TCD oven; a Thermoelectric Generator (TEG) thermally connected to the TCD element; and a detector circuit configured to: determine thermal gradient in mixture gas, wherein the mixture gas is mixture gas of carrier gas and analyte gas fed to TCD oven; and generate electrical signal based on thermal gradient.

Abstract: A device includes a fluid intake configured to receive a fluid comprising a fluid sample and provide the fluid to an inlet of a manifold plate. The manifold plate includes an inlet channel that is configured to deliver the fluid sample from the fluid intake to an analytical module, and a vent channel that is configured to receive the fluid sample from the analytical module and deliver the fluid sample out of the manifold plate to the fluid intake. The analytical module is affixed to the manifold plate, and includes a gas chromatograph oven that is configured to obtain the fluid sample from the inlet channel and expel the fluid sample using the vent channel after measuring an attribute of the fluid sample and sensors configured to measure the attribute of the fluid sample in the gas chromatograph oven after receiving the fluid sample from the manifold plate.

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.

Abstract: The present invention describes a novel subset of human hematopoietic stem cells that are defined by the ability to express transduced genetic material, and methods for producing the same. The transduced hematopoietic cells are preferably comprised of primary human CD34+ cells.
