Apparatus for providing gaseous sample ions/molecules and a corresponding method

摘要

An apparatus for providing gaseous sample ions/molecules from liquid droplets containing sample ions/molecules. The apparatus has a chamber having one or more walls which define an interior of the chamber, the chamber being configured to receive liquid droplets containing sample ions/molecules. The apparatus also has a gas flow producing means configured to produce a flow of gas within the chamber for promoting evaporation of liquid droplets in the chamber to provide gaseous sample ions/molecules. The apparatus is configured such that the flow of gas produced within the chamber inhibits liquid droplets in the chamber from coming into contact with the one or more walls of the chamber.
