Abstract
Abstract A detector system for detecting a target material in a sample includes a resonance chamber containing the target for performing magnetic resonance thereon to form dissociated target molecules. A laser is provided for pre-ionizing background material in the resonance chamber and for ionizing the dissociated target molecules. A sensor array detects radiation emitted from the ionized target molecules and a mass spectrometer, which is coupled to the sensor array, analyzes signals from the sensor array to generate a frequency pattern of the target. Electronically stored data tables of known frequency patterns are used for comparing the frequency pattern of the target to the known frequency patterns until a match is determined.
