Abstract
An apparatus and method for sampling semivolatile compounds is disclosed. A collection bag is placed around an air conditioning vent on an aircraft. An opening in the collection bag receives air from the air conditioning vent into the bag. An exit in the collection bag allows the air sample to escape from the collection bag. Vacuum applied by tubing at the exit pulls the air sample from the bag. Flow is adjusted so that the inflow into the collection bag exceeds the outtake, thereby inflating the bag. The inflation of the collection bag assures that the air being sampled is only air originating from the air conditioning vent.
Claims18
An apparatus for collecting an air sample from a vent comprising:
- a collection bag having an interior and an exterior, said collection bag further defining a collection opening, an overflow escape, and an exit;
- means for affixing said collection opening around an air conditioning vent;
- and
- a tubing for conducting air having an upstream end and a downstream end, the upstream end of said tubing affixed to the exit of said collection bag.
An apparatus for collecting an air sample from an aircraft air conditioning vent comprising;
- a flexible collection bag defining an interior, an exterior, a collection opening, an overflow escape, and an exit;
- a fastener that affixes the collection opening of said collection bag around an aircraft air conditioning vent;
- a flexible tubing having an upstream end and a downstream end, and the upstream end of said tubing affixed to the exit of said collection bag.
A method for collecting an air sample from an aircraft air conditioning vent comprising the steps of:
- providing a collection bag having an interior and a collection opening with the collection opening affixed around an air conditioning vent;
- attaching a tubing with an upstream end and a downstream end to a collection bag exit at the tubing upstream end;
- applying a vacuum at the tubing downstream end;
- and
- allowing air to escape from the interior of the collection bag through an overflow escape.
