Research output: Contribution to journalConference articlepeer-review


Moisture impurity adsorption and desorption from anodized aluminum layers was studied using atmospheric pressure ionization and electron-impact ionization mass spectroscopic techniques. In this work, one inch OD tubular samples (Sample A) from a major semiconductor tool manufacturer and 1 inch×4 inches×1/8 inch flat coupon samples (Sample B) from a company who specializes anodizing processes were studied. Strong moisture interaction with porous anodized aluminum layers was observed in the work.
