Direct Analysis in Real Time (DARTTM) refers to an atmospheric-pressure “open-air” ion source that is based on the interaction of long-lived (“metastable”) excited-state neutral atoms or molecules with analytes and atmospheric gases. The DART source is used for the rapid analysis of liquids, solids, vapors, or materials on surfaces in open air with little or no sample preparation.
