Abstract

A detector apparatus and preconcentrator capable of generating a flow of ions directed towards the adsorbing surface such as to increase flow of the gas or vapour onto the adsorbing surface is provided. Also provided is a method concentrating a sample gas or vapour using a preconcentrator capable of generating ions capable of flowing towards an absorbent material, allowing the sample gas or vapour to flow towards the absorbent material, and adsorbing sample gas or vapour particles onto the absorbent material.
