Abstract
Trace impurities such as organic compounds in an inert, non-reactive or reactive liquid such as ammonia, hydrogen chloride, hydrogen bromide, and chlorine are reduced by at least a factor of 5 using liquid purifying systems that contain an ultra-low emission (ULE) carbon. The moisture level of the purified reactive liquid is only slightly higher than that of the contaminated liquid.
