MÖSSBAUER STUDIES OF A SYNTHETIC ANALOG FOR THE ACTIVE SITE IN REDUCED RUBREDOXIN

A method of analyzing a sample gas for the presence of at least one gas impurity by combining a stream of sample gas with a stream of carrier gas to provide a combined stream of gas, directing the combined stream of gas through a column which preferentially removes the sample gas from the combined stream to produce a retentate stream of gas, and analyzing the retentate stream of gas for the presence of the at least one gas impurity.
