Abstract
An exchange membrane unit includes a first separation membrane, a first space that is connected to a second space via the first separation membrane, a first path that supplies a first fluid (carrier gas) to the first space and supplies chemical substances, which have passed through the first separation membrane from the second space into the first space and diffused, to an ion detector using the first fluid discharged from the first space, and a first ionizing unit provided in the first space. It is possible to provide a preprocessing system that produces little pollution and enables an ion detector to operate with high sensitivity. The present invention can be applied to FAIMS.
