1. A method of forming a stable electrospray of a volatile liquid in a low pressure environment comprising the steps of:

  • a. supplying one or more liquids into an emitter electrode located in a low pressure environment, wherein one of said liquids is a volatile liquid, and b. establishing a voltage difference between said emitter electrode and one or more surrounding electrodes or grids, wherein a meniscus formed by said one or more liquids supplied to said emitter electrode forms one or more Taylor cones, from whose tip region at least one of drops and ions of said one or more liquids are ejected, wherein a tendency of said volatile liquid to freeze, boil, or evaporate is diminished by a suitable evaporation-reduction means.
