Dear Fellow Vacuum Enthusiasts,
     Substances such as Linde 13X molecular sieve and coconut shell
charcoal are good adsorption agents at liquid nitrogen temperatures. Can
anyone direct me to data that gives the adsorption efficiency of these and
similar substances at higher temperatures in the vicinity of -100C? Thanks
for any help.
