Purifier

Microelectronics requiring extreme purity tolerate less than 1 ppb of impurity (0.0000001%) in its process and carrier gases. For this industry, ULTRALTM, Air Liquide’s line of cryogenic purifiers, has been designed to purify helium, hydrogen, nitrogen or argon by reversible cryogenic trapping on a high performance adsorbent bed.
