  • System and method for sampling metal ions in corrosive gas
    Patent number: 12228478
    Abstract: A system and method for sampling metal ions in a corrosive gas is provided. The system includes: a sampling bottle; a vacuuming pipeline provided with a vacuuming device, where the vacuuming device is configured to vacuum a sampling chamber; a replacement gas pipeline configured to blow a replacement gas into the sampling chamber; an injection pipeline configured to inject a sample gas into the sampling chamber; and a purge gas pipeline. With the sampling system, the sampling bottle can be first subjected to vacuuming and thorough replacement to reduce the interference of impurities, then the sampling bottle is introduced with a corrosive sample gas, and then a corrosive gas is vaporized and blown away through a purge gas to leave metal ions or metal ions are dissolved in an absorption solution.
