A system for forming a time modulated electrospray from a sample solution is provided. Further systems for analyzing this time modulated electrospray are provided. In a preferred such further system, a grid connected to a time modulated voltage source is provided between an electrospray apparatus and an analytical apparatus. More generally, a system for changing the energy of charged particles in a gas comprising the application of time modulated electric fields is provided.

Time modulated electrified spray apparatus and process

A housing is provided for converting an electrospray into a desolvated ion stream for analysis. The housing is positioned between an electrospray device and an ion stream analytical device. The housing is heated and includes a passageway within which a moving electrospray is converted to the ion stream.

Housing for converting an electrospray to an ion stream

An electrically insulated needle tip is provided for forming an electrospray from a solution containing a solute sample. The insulated needle tip is positioned between an upstream electrode and a downstream counterelectrode. The solution passes through the needle, emerges from the insulated tip and is converted to an electrospray under the influence of an electric field generated between the electrode and the counterelectrode.
