Большие универсальные фильтры газа-носителя Аджилент

Big universal traps utilize a layered, multi-adsorbent bed packing of the most effective, highest-capacity adsorbent materials available today for the removal of oxygen, moisture, hydrocarbons, carbon dioxide, and carbon monoxide from helium gas streams.

One Big Universal Trap unit will easily purify the contents of thirteen "K" size cylinders of 99.997% purity helium to a cumulative level of 100 parts per billion of O2, H2O, CO2, CO and hydrocarbons at a flow rate of up to 8 liters/minute. All tube fittings are Swagelok brand stainless steel, fitted with 40 micron stainless steel frits for particulate control. Maximum pressure is 500 psi.

Big Universal Traps are more economical than other purifiers. They cost only slightly more than competitive products, but offer nearly three times the capacity.

Big Universal Traps are ideal for any GC or GC/MS application where helium is employed and assurance of purity is essential. Combining the contents of three individual in-line traps into a single unit reduces the number of potential leaks and the possibility of aspirating contaminants into the gas stream. A single purifier also simplifies installation and replacement.
