CP-Molesieve 5Å 

This molecular-sieve coated capillary column is especially valuable when separating permanent gases. Analysis times are reduced by up to 75% compared to packed columns. On the CP-Molesieve 5Å, baseline separation of Ar/O2 is achieved at ambient temperatures. The column’s thin layer dimensions produce fast elution of CO with symmetrical peaks. High resolution analysis of permanent gases is assured.
