Sampling cartridge for gas sampling apparatus |
摘要 |
A sampling cartridge for a gas sampling apparatus includes a shell having a cylindrical wall and a sampling window extending through the wall. A pair of spools are coaxially and internally positioned within the shell. The spools are independently rotatable relative to the shell. A first spool may include multiple interval sample collectors while the second spool includes a duration sample collector. Each spool also has a window closing surface which is positioned adjacent the window whenever an access door of the gas sampling apparatus is opened. The sampling cartridge may also include a fully encapsulated section of sample collector material as a negative control, and an integral RF tag for storing chain of custody information including personal identification information of a cartridge replenisher.
