The requirement for ultrapure steam in many applications can be met by a new hydrophilic membrane for purifying water vapor that is nonporous and extremely selective.

The second in a two-part article on CO₂ in beer. Our initial article discussed CO at the point-of-use. Th is article explains a method for measuring CO₂ at the brewery.
