The second method achieves only 60% purification from raw sample, but when combined with the first, the result is 100% purity because no Shared contaminants co-elute with the product.
A glass tube containing catalyst 401 which is used as a color indicator for trace amount of oxygen was connected with the sample tube to monitor the purity of carrier gas during operation.
