  • Temperature control of chemical detection system
    Patent number: 10578578
    Abstract: An apparatus for detecting chemical reactions may be provided. The apparatus may comprise a chemical detection device. The chemical detection device may include a chemical sensor, which may be mounted on the chemical detection device. The apparatus may further comprise a valve block. The valve block may fluidly couple a plurality of reagent containers to the chemical detection device. The apparatus may further comprise a heat exchanger and a controller. The controller may control a fluid connection between the valve block and the chemical detection device. The controller may be also configured to adjust a temperature of a selected reagent from the plurality of reagent containers via the heat exchanger. The temperature of the selected reagent may be adjusted prior to the reagent entering the chemical detection device.
