Zeke; Activated alumina or zeolite will remove the water. One source I know of is companies like Kurt J. Lesker, Alcatel, Leybold and Pfeifer who are a supplier for industries that use high vacuum. The material is sold for foreline traps also known as a molecular sieve. The alumina can be baked to remove the water later and reused almost indefinitely.
