The present application discloses a fluidic system, a control method, a sequencing system, and a storage medium. The fluidic system includes a reaction device, a pipeline, and a degassing device. The reaction device is configured to provide a site for carrying out biochemical reactions. The pipeline is in communication with the reaction device and configured to deliver liquid to the reaction device and / or receive liquid flowing out from the reaction device. The degassing device is connected to the pipeline and configured to remove gas from the liquid in the pipeline. In this way, by removing gas from the liquid in the pipeline using the degassing device, the formation of bubbles in the reaction device can be reduced.

The utility model discloses an intelligent ventilation cabinet which is used for extracting experiment waste gas generated by experiment liquid and is in signal connection with a block chain network. The intelligent ventilation cabinet comprises a ventilation cabinet body, a chip set and a detection module. The ventilation cabinet comprises an experiment groove, a movable door and an air draft pump. The experiment groove is used for containing experiment liquid. And the movable door is movably connected with the experimental tank. The air draft pump is communicated with the experiment groove and used for extracting experiment waste gas. The chipset is arranged in the ventilation cabinet, the chipset comprises a block chain information tracing piece, and the block chain information tracing piece is in signal connection with the block chain network and is used for recording the source of the experimental liquid and a circulation process of the experimental liquid in the block chain network for tracing. The detection module is arranged in the ventilation cabinet and is in signal connection with the chipset; and the detection module is used for measuring the gas property of the experimental waste gas.

An apparatus and method for determining the presence of a disease by analyzing a specimen by providing a vial partially containing the specimen and partially containing a headspace above the specimen, injecting an inert gas into the specimen in the vial to cause bubbling of the gas throughout at least a portion of the specimen such that the gas mixes with volatile organic compounds (VOCs) present in the specimen to create a VOC / gas mixture that is released into the headspace, collecting the VOC / gas mixture from the headspace in the vial, supplying the VOC / gas mixture to a chamber within the apparatus, causing the VOC / gas mixture to pass over a sensor array in proximity to the chamber, the sensor array generating an electrical signal as a function of VOCs detected in the VOC / gas mixture, and processing the electrical signal to determine the presence of a disease in the specimen.

This invention discloses a cooling device and method for collecting soil respiration gases. The device includes a motor, a water pump, a breathing ring, a water pipe, a water bucket, a switch, an external power cord, a water inlet, and a water outlet. The motor and water pump are assembled together in a sheet metal assembly box. The motor is fixed to the cover on the top surface of the sheet metal assembly box, and the water pump is fixed to the base of the sheet metal assembly box. The motor and water pump are connected by an electric wire. The switch and external power cord are installed at the rear of the sheet metal assembly box. A water inlet is set on the side of the sheet metal assembly box near the water pump, and a water outlet is set at the front of the sheet metal assembly box. The water outlet is connected to the breathing ring through a water pipe, and the breathing ring is connected to the water bucket through a water pipe. Water in the water bucket is connected to the water inlet of the sheet metal assembly box through a water pipe. Ice blocks are placed in the water bucket. This invention solves the problem that the temperature in the breathing chamber gradually increases with the increase of the sealing time, thereby affecting the rate of soil respiration and carbon emissions.
