A cryosurgical unit consists of five main components: a nitrous oxide gas cylinder, the cryogen or gas, a pressure gauge, a cryogun with tubing, and assorted cryoprobe tips (Figure 2).
Unlike other procedures in which liquid nitrogen is used, in cryosurgery, the nitrous oxide remains within the probe tip, and the cryogen is not applied directly to the tissue.
Overuse of cryogens during blending is drawing some attention.
Nitrogen has made significant inroads as a blending cryogen in Europe, but it has lagged badly in the United States, mostly because C[O.sub.2], on the average, is less expensive.
But it also means that C[O.sub.2] source industries can affect the supply of that cryogen. For instance, an explosion in a large fertilizer plant in Iowa late last year disrupted C[O.sub.2] supplies to a large portion of the Midwest, said Pascal Schvester, a marketing manager with Air Liquide America Corp.
Aside from price, each cryogen has its relative advantages.
The system was specifically developed for conveniently filling dewars for gas adsorption instruments but also can be used for other cryogen applications.
