Installation Checklist for GC Columns—Restek Innovations and Technical Services specialists have found this checklist to be a reliable sequence for avoiding problems when installing a capillary GC column.
Molecular sieve materials are very hydrophilic
Because molecular sieve materials are very hydrophilic, they will adsorb water from the sample or carrier gas. Water contamination can have a detrimental effect on peak symmetry and can reduce the resolution of all compounds. If water contamination occurs, reactivate your Rt®-Msieve 5A PLOT column by conditioning at 300°C with dry carrier gas flow for 3 hours.
