A smart fume hood is used for extracting the experimental waste gas generated by an experimental liquid and is electrically connected to a blockchain network. The smart fume hood includes a fume hood, a chipset, and a detection module. The fume hood includes an experimental tank, a moving door, and a peristaltic pump. The experimental tank is used for holding the experimental liquid. The moving door is movably connected to the experimental tank. The peristaltic pump is connected to the experimental tank and used for extracting the experimental waste gas. The chipset is located in the fume hood and includes a blockchain information tracking part. The blockchain information tracking part is electrically connected to the blockchain network and used for recording the source and logistics information of the experimental liquid on the blockchain network for tracing.

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.

A system for collecting a sample of a gas in an aqueous environment is described herein. The system includes a collection vessel having a body having a cavity and a bottom edge forming a perimeter around an opening on an underside of the body. The opening is sized to receive the sample of the gas into the cavity as the sample of the gas travels upwardly and the main body is positioned directly above the sample of gas in the aqueous environment. The collection vessel also includes a valve coupled to the body. The valve provides for the sample of the gas to be removed from the cavity without travelling through the opening on the underside of the main body. The collection vessel also includes a confinement structure having a and a coupling mechanism configured to retain the collection vessel at least partially in the confinement structure.
