An air sampler module is provided for use with a detection device that monitors liquids and/or solids on a surface using spectroscopy techniques. The air sampler module comprises a housing, an intake port for collecting air containing airborne threats to be analyzed by the detection device, and a port to permit communication of an optical transceiver of the detection device into the housing to permit analysis of the collected air. Thus, the capabilities of a spectroscopy detection system are expanded to include the ability to analyze airborne threats.
