Description Indicating Oxy-Trap™ is a compact unit designed to remove oxygen from carrier gas streams. Its indicating characteristics warn you when the adsorbent must be regenerated. The color change is sharp and vivid, turning from beige to dark brown. The unit works with nitrogen, helium, hydrogen, argon, argon/methane mixtures, alkanes, etc. When used in series on the downstream side of our larger capacity Non-Indicating OxyTrap™, there is a positive indication as to when regeneration is required to maintain an oxygen-free carrier gas stream. Design The Indicating Oxy-Trap™ is supplied with the catalyst in a reduced state, ready for use. By necessity, the indicating adsorbent is supplied in a heavy-walled, 3/8" o.d. borosilicate glass tube which prevents air from entering the system and allows for visual inspection. The Indicating Oxy-Trap™ (Part No. 4004) has a non-indicating, higher capacity catalyst at each end to protect the indicating material from oxygen exposure during installation. The Super Indicating Oxy-Trap™ (Part No. 4334) has one band of indicating material near the outlet end, in order to accommodate a larger amount of high-capacity catalyst. The traps are protected with a clear, shrinkable plastic cover to minimize breakage hazards. Overall length is 18 inches. The Indicating Oxy-Trap™ is used for removing the last few parts per million (ppm) of oxygen from an already purified gas stream. The oxygen level is below the limits detectable by ASTM Method D 2223. The units are self-indicating, alerting you when regeneration is required. If disposal is preferred over regeneration, dispose as you would any solid chemical. The color change between fresh and spent catalyst is quite vivid. The active catalyst has a sand-like color which changes to dark brown upon contact with oxygen. Normally, there is a sharp boundary separating the spent from the fresh catalyst. With use, the front advances slowly, depending on the
