Abstract: A portable device includes a base unit, an extension, and a mirror. The base unit includes a light source, a light detector, and at least one window through which light exits from, and is received by, the base unit. The extension is configured, during use, to be attached to the base unit and to extend from the at least one window, in a direction away from the base unit, the extension defining at least a portion of a sample volume in fluid communication with gases substantially surrounding one or more of the extension and the base unit. The mirror is attached to the extension at a distance from the at least one window. An optical path is defined between the mirror and the at least one window such that light from the light source moves through the sample volume along the optical path, and the mirror is aligned to reflect the light back to the at least one window for detection by the light detector.
