Abstract:
1. A method for detecting a high boiling point and/or a low vapor pressure material, comprising: providing a housing comprising an inlet, a strobe, a gas source, and a detector, wherein the housing at least substantially surrounds the strobe and the inlet and wherein the inlet is positioned between the strobe and a surface potentially comprising a high boiling point and/or low vapor pressure material; directing radiation from the strobe onto the surface to volatilize the high boiling point and/or low vapor pressure material, the directing radiation step is conducted over a time period of no more than about 1/100 transporting an airborne sample comprising at least a portion of any volatilized high boiling point and/or low vapor pressure materials on the surface through the inlet and through a heated conduit to the detector, wherein an internal surface of the heated conduit is maintained at a temperature sufficient to inhibit absorption and/or condensation of the high boiling point and/or low vapor pressure material on the internal surface, and wherein the heated conduit extends from the inlet to the detector; and detecting whether or not the high boiling point and/or low vapor pressure material is present in the collected sample.
