Silcoport®PackingMaterials
OutperformAnyDeactivatedDiatomaceous EarthSupportsAvailable!
• Superior deactivation technology for improved inertness.
• Available in80/100 and100/120mesh.
• Uniformparticle distribution formaximum efficiency.
The increased sensitivity of modern detection systems and the desire to reduce detec-
tion limits requires a solid support tomeet the challenging demands facedby 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 acidwashed deactivation.

• CarboBlackC supports up to1% loadingof anonsilicone liquidphase.
• Equivalent toSupelco’sCarbopack™packings.
Graphitized carbonblackoffersunique selectivity andvery little adsorption for alcohol
analyses. Two types of CarboBlack supports are available, CarboBlack B and
CarboBlackC.CarboBlackB support,with itshigher surfacearea, canholdup toa10%
loadingof anonsilicone liquidphase.CarboBlackC support canholdup toa1% load-
ing of a nonsilicone liquidphase.ManyCarbowax® 20M-loadedCarboBlackpackings
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.
