GC Column Installation Checklist

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.

What are the differences between Rtx®-5MS columns and Rtx®-5Sil MS columns?

Rtx®-5MS columns are coated with a 5% diphenyl/95% dimethyl polysiloxane phase and are tested to rigorous specifications for low bleed and inertness. They have polarity identical to Rtx®-5 columns, but exhibit lower bleed. Rtx®-5Sil MS columns are coated with a silarylene phase that exhibits polarity very similar to a 5% diphenyl/95% dimethyl polysiloxane phase, but the phenyl rings in the polymer chain of the silarylene phase impart improved thermal stability and lower bleed. The Rtx®-5Sil MS column is an ideal choice for analyzing EPA Method 8270 semivolatile pollutants. The slight difference in the polarity of Rtx®-5Sil MS columns also improves separation of benzo(b)- and benzo(k)- fluoranthene isomers.
