GDS-DL42 Gas Liquid Fully Automatic Dynamic Gas Distribution System Introduction: The GDS-DL42 gas liquid solvent distribution system includes 3 gas dynamic distribution channels and 1 liquid solvent distribution channel. The corresponding standard gases prepared can be widely used in various departments and industries such as environmental monitoring, disease control centers, traffic safety, military industry, home decoration and building materials, petroleum, chemical industry, research institutes, etc; It can be used to prepare standard gases such as SO ₂, NO, NO ₂, CO, O3, H ₂ S, HCl, etc. It can also be used to prepare liquid solvent volatile gases such as ethanol, methanol, ether, etc VOC、 Acetone, benzene, cyclopentane, epoxyethane and other organic gases are used for the calibration, calibration and analysis of online monitoring and analysis instruments, portable analytical instruments, laboratory analytical instruments, sensors, etc., as well as the use of fixed value standards for analysis methods. The gas mass flow controller is used to control the gas mass flow rate in real time, and a fully automatic micro injection liquid solvent gas generator is used to achieve full automation of the gas distribution process, realizing the dilution and preparation of standard gases. Liquid organic solvents are liquids at room temperature and have strong volatility. Organic solvents are transported through the fully automatic quantitative injection system of GDS-DL42 and heated to the set temperature. At the same time, they are vaporized into a high concentration mixture under the action of a constant current carrier gas. The high concentration mixture is mixed with a dilution gas to prepare various low concentration mixed standard gases as required. This system can prepare mixed standard gases of various standard gases and organic solvent gases. Characteristics: 1. Simultaneously support 1 channel of liquid solvent gas and 3 channels of gas distribution 2. Liquid solvent injection method: Fully automatic microsampler injection, no manual intervention required 3.
