Abstract
The present invention provides a sample cartridge for use with an air and gas sampling device. The cartridge includes a body that defines an interior space, a top portion attached to the body and substantially covering the interior space, and first and second valves seated in the top portion of the cartridge. The valves automatically seal to prevent leakage from the cartridge when the cartridge is not in operable position within the air and gas sampling device.
