Claricep? Flash 正相硅胶具有SiO4四面体结构,活性的亲水表面.水分子与裸露的表面通过氢键作用,形成酸性的硅胶.多孔性质和硅醇功能基团使硅胶成为一种经济的色谱分离材料,可以分离弱极性化合物,而此时需要用极性更弱的流动相.我们采用超纯二氧化硅装填(经酸和去离子水洗涤,较窄的粒径范围以及精确控制含水量)

Silica-based columns are made with high purity analytical grade silica and are suitable for most flash chromatography systems.Special surface modification greatly reduces over-activity of the silica surface,which reduces tailing of compounds and ensures high recovery and good reproducibility.The unique HILIC columns allow the purification of highly polar compounds which are not suitable for bare silica or ODS columns.
