Vous avez recherché : Filtres à gaz
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.

Gas trapping systems for LC/MS, Super Clean®
Supplier: Restek
The Super Clean® gas trapping system purifies nitrogen and is ideal for use in LC-MS systems. The two position base plate (installed in the gas line; standard base plate inlet/outlet fittings accept ¹/₄" tubing) allows cartridges to be exchanged without introducing impurities into the system. To meet the high flow needs of the LC-MS system, the activated charcoal filled cartridges are positioned and connected in parallel.

Gas-clean filters
Supplier: PerkinElmer
The fuel gas triple kit is perfect for purifying carrier gas and flame ionisation detector (FID) fuel gases, removing oxygen, moisture and hydrocarbons from the carrier gas using the triple filter and removing both moisture and hydrocarbons from the fuel gas using the two combi filters. Using the combi filters for FID hydrogen and air will produce a stable baseline, improving overall reproducability and sensitivity.
