Abstract
This invention discloses an apparatus for studying atmospheric chemical and biological reactions. The apparatus comprises: a gaseous pollutant generation module, including at least one independent gas generation sub-module; a humidity control module for regulating airflow; a gas mixing chamber, with its inlet a connected to both the gaseous pollutant generation module and the humidity control module; a reaction chamber, with a sample holder inside its shell, an inlet b and an outlet b on the shell, and a single-sided opening for placing biological samples on the sample holder, the opening being fitted with a removable sealing plate; the inlet b connected to the outlet a of the gas mixing chamber; the outlet b connected to a pollutant monitoring module; and the pollutant monitoring module for monitoring the gaseous pollutants flowing out of the reaction chamber. All the above components are connected via gas paths. This invention is simple to operate, has a wide range of applications, and allows for controllable gaseous pollutant concentration and contact time.
