Abstract
The present invention discloses a portable sampler for collecting an atmospheric sample. In one implementation, the portable sampler includes a portable housing with an interior portion; a sample inlet communicating between an area outside the housing and the interior portion of the housing; a sample cartridge in fluid communication with the sample inlet and adapted to store the atmospheric sample, the sample cartridge being removably secured within the housing; a pump disposed within the housing and in fluid communication with the sample inlet, the pump being arranged to draw the atmospheric sample from the area outside the housing into the sample cartridge through the sample inlet; and a carrier gas inlet communicating between the area outside the housing and the sample cartridge, the carrier gas inlet being configured to couple with a carrier gas source for sweeping the atmospheric sample from the sample cartridge into an analyzer while the sample cartridge is secured within the housing.
