Chromosorb® P (used to prepare Silcoport® P)
Chromosorb® P support is manufactured from hard firebrick, making it a rugged
material. This support is available acid washed (AW), nonacid washed (NAW), and tra-
ditional dimethyldichlorosilane (DMDCS) treated. Chromosorb® P support can hold
up to 30 weight% of liquid stationary phase, making it the highest loading support
available.
Chromosorb®W (used to prepare Silcoport®W and Silcoport® BW)
Chromosorb® W support is a flux-calcinated diatomite. This solid support is very frag-
ile but offers the highest inertness of all diatomaceous earth supports. It can be prepared
with up to 25 weight% of liquid stationary phase. Chromosorb® W support is available
in AW, NAW, and DMDCS, or treated with Restek’s proprietary (Silcoport®) deactiva-
tion. Chromosorb® W-HP is an acid washed, silanized version of Chromosorb® W.
Chromosorb® G
Chromosorb® G support is the hardest support available and has the lowest surface area
of all the diatomaceous earth supports. Chromosorb® G support is available as AW,
NAW, and DMDCS-treated. It can hold up to 10 weight% of liquid stationary phase.
Chromosorb® T
Chromosorb® T support is made from Teflon® material and is an extremely inert solid
support.
Chromosorb® G and Chromosorb® T are available as custom products. Contact us for
more information.
