A sensor for detecting a target analyte in a gaseous sample at ultra-low concentrations wherein access opening(s) provided through the sensor housing are plugged with endcap(s) and spent gas ( i.e ., gaseous sample post detection) is channeled along the interface between the sensor housing and the endcap(s) prior to venting of the spent gas, for flushing any environmentally introduced target analyte from this interface. |
