Apparatus for mobile collection of atmospheric sample for chemical analysis
First Claim
1. A portable sampler for collecting a sample, the portable sampler comprising:
- a portable housing having an interior portion, wherein the portable housing is configured to removably secure a sample cartridge within the interior portion, the sample cartridge having a self-sealing inlet port and a self-sealing outlet port, the portable housing further configured to open the self-sealing inlet port and the self-sealing outlet port when the sample cartridge is secured therein;
a sample inlet in communication with an area outside the housing and configured to establish fluid communication with the sample cartridge when the sample cartridge is secured;
a pump configured to draw a sample into the sample cartridge through the sample inlet when the sample cartridge is secured;
a processor configured to operate the sampler;
an input/output interface; and
a detection trigger configured to detect the presence of at least one predetermined chemical, the processor being further configured to take a sample when the detection trigger detects the presence of the at least one predetermined chemical.

Abstract
Portable devices and related methods for collecting and storing atmospheric samples for subsequent chemical analysis are provided. A sample cartridge according to one implementation includes self-sealing inlet and outlet ports configured to close automatically when not in use, and a sample retention portion between the inlet and outlet ports that is adapted to trap an atmospheric sample. The sample cartridge may also include a memory device for recording data regarding the sample. Another embodiment provides a portable sampler configured to removably secure a self-sealing sample cartridge. A portable sampling device may also be used with an analytical instrument. The analytical instrument may analyze the sample and read the data recorded on the sample cartridge'"'"'s memory.
