On-the-move surface sampling head for a mass spectrometer

An on-the-move direct-contact surface sampling head for use with a gas analyzer such as a mass spectrometer or the like which comprises:

• a transfer line having an output end connector for connection to a gas analyzer, an input end connector, a plurality of electrical power wires extending between and terminating at said input end connector and said output end connector, and a hollow transfer tubing extending between and terminating at said input end connector and said output end connector;
• and
• sampling head means detachably connected to the input end connector of said transfer line for contacting surfaces to be examined from a moving platform to determine existence of chemical contaminants,
• said sampling head means including a permeable membrane member having an outer surface for contacting the surface to be examined and having an other surface, means enclosing said other surface to form an interior chamber therewith, said means enclosing said other surface including a sampling head connector configured for mating engagement with said output end connector of said transfer line, heating means disposed within said interior chamber for heating said other surface and having electrical connection ends terminating in said sampling head connector for mating engagement with said electrical power wires of said transfer line, and air port means extending through said sampling head connector into communication with said interior chamber and positioned for mating engagement with said hollow transfer tubing of said transfer line.
