Method and apparatus for gas filter testing |
| abstract |
A method is described to determine the remaining sorption capacity of activated-carbon-sorbent gas filters by measuring the breakthrough time for a test gas challenge to a test filter with known and controlled test conditions that include flow rate and temperature and the use of a calibration curve that has been established by prior testing of the test filter sorbent medium in calibration tests where the filter is exposed to a known quantity of gas surrogate for the challenge gases that the filter may sorb in service and then testing the test filter medium by challenge with a sparged gas that can be selectively detected to determine the breakthrough as a function of test gas. The apparatus using such a method comprises a portable system that includes a sparging test gas generator, a carrier gas system, a test filter canister holder, and a selective detector that can quantitatively monitor the test gas exiting the test filter canister. The method and apparatus can be used to determine the remaining sorption capacity of activated carbons filters, e.g., ASZM-TEDA carbon filters such as those used for building defense against chemical toxant attack, industrial accidents, and for tactical collective protection and for industrial ventilation and compliance with environmental regulations. |
