Macroporous Silica Sorbents |
|
|
|
Based on the TESSEK Separon SGX, those sorbents are prepared by special
treatment to provide material with large pores possessing a narrow pore size
distribution.
|
|
TESSEK Separon SGX 200 - is prepared by hydrothermal treatment and is
intended for size exclusion chromatography of organic solvent soluble polymers
in the molecular weight range 1 - 100 kDa.
|
|
TESSEK Separon SGX 500 and 1000 are two macroporous silicas for size
exclusion chromatography of organic solvent soluble polymers in the molecular
weight ranges 10 - 1 000 kDa and 50 - 3 000 kDa respectively.
