Apparatus for mobile collection of atmospheric sample for chemical analysis

摘要

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.
