Chromosorb Packings
Restek offers the full line of Chromosorb? solid supports. Choosing the appropriate support will depend on your application. Need assistance?RESTEK提供全系列的Chromosorb型硅藻土色谱填料,填料经过了严格的筛选以去除细末,保证颗粒尺寸分布集中。根据具体应用选择所需填料。
Chromosorb P (used to prepare Silcoport TM 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 traditional 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 fragile 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?) deactivation. 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.
Chromosorb P(used to prirare Silcoport P)
Chromosorb P型色谱填料是由硬的耐火砖制造,在天然硅藻土中加入木屑及少量黏合剂于900摄氏度左右锻烧,就得到这种红色硅藻土载体。这是一种相当耐用的材料,机械强度较高。可以用酸洗、非酸洗 、传统的二甲基氯硅烷(DMDCS)处理。其可以承载30%重量的固定液。
Chromosorb W(used to prepare Silcoport W and Silcoport BW)
Chromosorb W型色谱填料是一种熔融-锻烧硅藻土载体,它是将天然硅藻土经盐酸处理后干燥,再加入少量碳酸钠助剂在1100摄氏度左右煅烧,就得到这种白色硅藻土载体。这种担体十分易碎,但是惰性是现有硅藻土中的,能用于高温分析。其固定液承载量可达25%,Chromosorb W填料可以使用AW、NAW、DMDCS等清洗。也可以用Silcoport工艺去活处理。Chromosorb W-HP是酸洗 的、硅烷化的Chromosorb W。
Chromosorb G
Chromosorb G型载体在所有的硅藻土中表面积zui低的。可以采用AW,NAW,和DMDCS处理。这种载体可能承载10%重量的固定液。
Chromosorb T
Chromosorb T型载体是一种Teflon制品,惰性。
NAW--nonacid washed
AW--acid washed
DMDCS--dimethyldichlorosilane
BW--base washed
