b.safe Exhaust Filters – a good calculation!


HPLC exhaust filters are mainly offered with service lives of 3, 6 and 12 months. What is the reason for these specific intervals and can you rely on them?

We calculated different scenarios to determine the service lives of our b.safe Exhaust Filters. Besides adsorption capacity and filling level of the activated carbon, the factors solvents, operating hours and flow rates are important. Under the given framework conditions, we can determine a realistic service life for each specific solvent.

In most cases, above mentioned service lives are appropriate. However, there are exemptions: highest flow rates, several units per canister and special solvents (keyword: hexane) shorten the service life.
