Sensitive instrument uses two low-energy electron beams to detect certain molecules. Experimental instrument identifies and measures trace contaminants in atmosphere. When fully developed, portable instrument expected to measure contaminant concentrations of certain halogen containing molecules as low as one part per trillion. Instrument employs electron beams to ionize contaminant molecules by dissociative attachment of electrons.
