Abstract
System and method for operating an ionizer using a combination of amplitude modulation and pulse width modulation to control the plasma temperature and the type of ions needed for analytic equipment. Ion density can be controlled by the repetition rate. The ionizer may utilize a non-radioactive ionization source, and be coupled to a differential mobility spectroscopy (DMS) analyzer.
