Packed Column Packing Materials
Res-Sil® Packing Materials
• Unique separation of saturated and unsaturated hydrocarbons.
• Innovative bonding chemistry for batch-to-batch reproducibility, excellent thermal
stability, and long life.
• Wide range of bonded phases available.
• Equivalent to Durapak and Porasil packings.
Bonded silica packings with n-octane or cyanopropyl (OPN) functional groups yield
faster separations of C1 to C4 hydrocarbons, higher thermal stability, shorter con-
ditioning times, and longer lifetimes than conventional packings. However, bonded
silica packings have had inconsistent reproducibility and limited availability. Restek’s
research team has solved these age-old problems by developing Res-Sil® C packings for
consistent performance.
Unique Selectivity for Process GC and High-Speed Analysis of Petrochemicals
Res-Sil® C bonded packings are ideal for fast resolution of difficult-to-separate satu-
rated and unsaturated C4 hydrocarbons (see ). This unique selectivity, when
combined with other columns in series, provides petroleum and petrochemical meth-
od developers with a powerful tool for fast determination of C1 to C5 hydrocarbons.1
Innovative Research and Stringent QC Provide Batch-to-Batch Consistency
Restek’s synthesis procedure eliminates batch-to-batch variations. The amount of
bonded liquid phase is precisely controlled in every batch for reproducible retention
times and separations. Each production batch of Res-Sil® C packing is tested with a
complex hydrocarbon mixture to meet demanding retention time and retention index
specifications and to ensure there are no retention shifts. Column bleed is also evalu-
ated to ensure that baselines remain low.
OPN on Res-Sil® C Packing—the Latest in a Line of Bonded GC Phases
Restek offers a wide range of bonded packings for packed column GC, including
Rtx®-1, Stabilwax®, and Carbowax® phases. We have extended this technology to make
n-octane on Res-Sil® C packing, and OPN on Res-Sil® C packing. Each of these pack-
ings has low bleed, conditioning times of less than 30 minutes, long lifetime, and
consistent batch-to-batch reproducibility.
Minimum order of 10 grams. Price is per gram.
