SYSTEM AND METHOD FOR TRACE DETECTION USING DUAL IONIZATION SOURCES

摘要

A dual source ionizer includes a first ionization source and a second ionization source. The first ionization source is configured to generate a first electric field. The first electric field has a first field strength that is insufficient to form NO x - ions. The second ionization source is configured to generate a second electric field. The second electric field has a second field strength that is sufficient to form ozone and the NO x - ions.
