Air-sampling cartridge |
| abstract |
An air-sampling cartridge is disclosed for collecting organic compounds such as N-nitrosamines from air for analysis. The cartridge is formed by joining two injection-molded plastic parts: a generally cylindrical cartridge body into which air-pervious packings of granular adsorbent materials may be loaded, and a cartridge cap which is ultrasonically welded to the body to partially close one end of the cartridge. The cap and body define a cartridge with an inlet and outlet shaped to facilitate connection of the cartridge to a pump used to draw air samples through the cartridge, to allow connection of two or more cartridges in series, and to accommodate standard-sized syringes used in removing trapped compounds from the cartridge for analysis. n The cartridge also includes a retention clip integrally molded with the cartridge body and cap for permitting the cartridge to be attached to the clothing of a person during air-sampling. Also provided are two shipping caps which are held within storage wells on the cartridge body during air-sampling and which at other times are used to seal the inlet and outlet of the cartridge to prevent contamination of the adsorbent material and compounds trapped therein. |
