5A molecular sieve separates permanent gases, including CO. Deactivation process. Molecular sieves have high retention and can separate permanent gases under conditions above room temperature Deactivation treatment technology can allow CO to be eluted with sharp chromatographic peaks.
Molecular sieve materials are very hydrophilic because they have strong hydrophilicity and can adsorb moisture that may exist in the sample and carrier gas. The residual moisture in the stationary phase can disrupt the peak shape and reduce the separation of compounds. When residual moisture is present in the stationary phase, the 5A chromatographic column should be aged at 300 ° C for 3 hours under dry carrier gas conditions to restore its performance.
