Silcoport® Packing Materials
Outperform Any Deactivated Diatomaceous Earth Supports Available!
• Superior deactivation technology for improved inertness.
• Available in 80/100 and 100/120 mesh.
• Uniform particle distribution for maximum efficiency.
The increased sensitivity of modern detection systems and the desire to reduce detec-
tion limits requires a solid support to meet the challenging demands faced by analysts.
Unlike conventional dimethyldichlorosilane (DMDCS) deactivation, Silcoport® incor-
porates our proprietary fused silica deactivation technology on diatomaceous earth
solid supports. Silcoport® supports were developed using a special mixture of deacti-
vants that yields the highest inertness without changing the polarity of the stationary
phase. Silcoport® supports from Restek are the perfect match for highly inert
SilcoSmooth® tubing.
*Prepared from Chromosorb P; Restek acid washed deactivation.

CarboBlack Packing Materials
• CarboBlack B supports up to 10% loading of a nonsilicone liquid phase.
• CarboBlack C supports up to 1% loading of a nonsilicone liquid phase.
• Equivalent to Supelco’s Carbopack™ packings.
Graphitized carbon black offers unique selectivity and very little adsorption for alcohol
analyses. Two types of CarboBlack supports are available, CarboBlack B and
CarboBlack C. CarboBlack B support, with its higher surface area, can hold up to a 10%
loading of a nonsilicone liquid phase. CarboBlack C support can hold up to a 1% load-
ing of a nonsilicone liquid phase. Many Carbowax® 20M-loaded CarboBlack packings
are available. CarboBlack packings are treated with KOH or picric acid for basic or
acidic compounds, and special alcoholic beverage loadings are available. CarboBlack
supports provide resolution and retention similar to Carbopack™ and Carbograph
supports.
