Abstract
A monitor that can detect a trace molecule that is ionized at approximately one atmosphere. The molecule is ionized with a photoionizer and detected by a detector. The monitor may include a number of techniques to introduce a sample into the photoionizer at approximately one atmosphere. One technique includes creating an electrically charged spray that is directed into the ionizer. The photoionizer may include a plurality of light sources that each ionize the sample with a different radiation energy.
