Gas Filters
Gas filters are used for purifying inert carrier gases for use in gas chromatography and anaerobic experiments. These filters can be either disposable or refillable. Desiccants and molecular sieves are utilized in removing water, oil, oxygen, hydrocarbons, and other contaminants that can damage chromatography columns. High-purity output due to a packed, extremely high surface area ensures ultra-pure gas, and filters are easy to replace for low maintenance.
