Silica based sorbents are still the most used packing materials in liquid chromatography today. They offer excellent efficiency and mechanical stability. Their limitations are in lower chemical stability, especially at higher pH and in remaining silanol groups activity in modified materials, resulting in non ideal behaviour of basic solutes.

TESSEK Separon SGX sorbents are based on a totally porous, spherical silica. The sorbent is prepared by original technology, ensuring high batch to batch reproducibility. It features high sorption capacity, good mechanical strength and chemical stability, wide pore size distribution. The average pore diameter is around 8 nm, the average surface area 500 m2 and the pore volume 1.0 ml/g. Standard particle sizes are 5, 7, 10 and 60 µm, others are available for specific purposes.
