An ion selecting method for identification of ions in gaseous media

Abstract

This method relates to selecting ions with a predetermined ion mobility from its mixture containing ions and electrically neutral molecules. More particularly, this method enables to extract ions of interest from a flow of analyzed gas so that they can be directed into a clean gas flow where they can be quantified. The method provides more effective separation, increases the resolution of ion selecting device and therefore enables to quantify complex mixtures at low concentrations molecules of interest in gases.
