Model 300 HC Filter

This a high-pressure metal cylinder filled with 500 cc of activated charcoal, one of the most effective adsorbents for organics and hydrocarbons. Removes C5 weight and heavier hydrocarbons from inert gases, air, or hydrogen to low ppb levels. It is also recommended for use with purge and trap apparatuses, and with GC carrier gases for trace analyses. Highest efficiency is obtained using flow rates below 500 cc/min. Frits in each end prevent fines from entering the gas stream. The Model 300 is delivered filled with high-purity helium; it should be purged before use with the gas you will be using.
