【 摘 要 】

This report summarizes hydrogen pumping by organic getters in the presence of carbon tetrachloride, and how the reduction of pumping in the presence of this catalyst poison can be minimized through the choice of catalyst. Catalyst A is shown to be preferred in a clean environment, and catalyst B for a poisoned environment. Additional, we examine the effects of temperature on pumping rates, and show that this getter is effective over a large temperature range from -23 to 107 degrees Celsius.
