APPARATUS FOR MOBILE COLLECTION OF ATMOSPHERIC SAMPLE FOR CHEMICAL ANALYSIS

摘要

Portable devices and related methods for collecting and storing atmospheri c samples for subsequent chemical analysis are provided. A sample cartridge according to one implementation includes self-sealing inlet and outlet ports configure d 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. Anothe r 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 da ta recorded on the sample cartridge's memory.
