Sorbents, Tubing, Fittings, Valves - Spherical silica

kouleSorbent - as prep columns filling - is an indivisible part of successful implementation of PLC separation process. Sorbent in preparative dimensions is also much important part than in analytical HPLC, as its replacement is problematic and expensive. This is the reason why we pay so much attention just on to sorbents.

SEPARSPHER SI sorbents bring to customer a lot of advantages. They are available in wide spectrum of particle size, pore size and modifications. They are available in an quantity as they are manufactured in big amounts. They are produced with high level of process control which gives to customers a warranty of excellent reproducibility. And finally - there is an assurance that they are available now and will be available in the future.

SEPARSPHER SI sorbents are perfectly spherical. They are made of highly pure raw materials and their matrix contains less than 100 ppm of total metals. RP modifications are following with endcapping which guarantees nearly no silanol interaction due the chromatography process. There is a special RP modification available for pure water applications where impends a "chain collapse".

SEPARSPHER SI C4 SE and DIOL modifications are delivered in broad pore range to allow to pack columns for size exclusion chromatography. These columns are recommended both for standard a chromatography of nonpolar synthetic polymers (C4 SE) and a chromatography of polar (mainly natural) water soluble polymers.
