Abstract

Concentration of chemical substances in a sample gas by electrostatic spraying in a simple and efficient manner without using a nebulizer gas and a gas for primary ion generation is intended. The electrostatic spraying device for use in the chemical substance concentration method of the present invention includes a vessel, an injection port, a cooling part, an atomizing electrode section, and a unit for recovery of the chemical substance in the counter electrode section. Furthermore, the chemical substance concentration method of the present invention includes the steps of : injecting a sample gas; producing a first condensate liquid from the sample gas; producing first charged fine particles from the first condensate liquid; producing second charged fine particles by mixing the first charged fine particles with the sample gas; and recovering the first charged fine particles and the second charged fine particles. According to a series of the operation described above, the chemical substances in the sample gas can be concentrated in a simple and efficient manner.
