Abstract : There is a pressing need for airborne hazard detectors for both Army and civilian use. Cavity ring-down spectroscopy (CRDS) is a capable and sensitive detection method for hazardous materials that is based on the principles of electromagnetic radiation spectroscopy. Research has been ongoing at the US Army Research Laboratory (ARL) to evaluate the sensitivity and limitations of two commercial CRDSs. These devices were manufactured by Los Gatos Research, Inc., and provided to ARL via collaboration with the Edgewood Chemical Biological Center (ECBC). Evaluation of the spectrometers comprises background noise determination, spectroscopic confirmation, and limit of detection testing. At each step, the CRDSs proved to be accurate and sensitive apparatus.
