Sample Preparation

SHIMSEN Styra FL-PR is based on natural Flori silica (MgO • SiO2) and is used for the recovery or cleanup of polar substances from non-polar solvents. This sorbent is high in polarity and can be used to extract polar compounds from non-polar solutions. The larger particle size (200 μm) of the sorbent enables fast flow for large sample volumes and is therefore an attractive alternative to silica if the sample matrix is particularly viscous. FL-PR can not only separate chlorinated insecticides, but also be used in AOAC, EPA and other methods. In addition, FL-PR is an excellent replacement for alumina cartridge when the acidic nature of alumina affects the extraction effect.

SHIMSEN Styra SI is based on unbonded silica gel particles. The primary interaction available is strong polar interaction due to the silanol groups. It can be used for enrichment of polar compounds from low-polar solvents or removal of polar impurities from non-polar solvents. It is necessary to prevent moisture absorption before use.

SHIMSEN Styra WAX uses a polymeric anion-exchange resin that combines the outstanding properties of SHIMSEN Styra HLB with weak anion exchange functionalities. WAX is suitable for the enrichment and purification of strong acidic compounds with pKa 1 or less.

SHIMSEN Styra MAX uses a polymeric anion-exchange resin that combines the outstanding properties of SHIMSEN Styra HLB with anion exchange functionalities. MAX is suitable for the enrichment and purification of acidic compounds with pKa 2-8.

SHIMSEN Styra WCX uses a polymeric cation-exchange resin that combines the outstanding properties of SHIMSEN Styra HLB with weak cation exchange functionalities. WCX is suitable for the enrichment and purification of strong basic compounds with pKa 10 or more.

SHIMSEN Styra MCX uses a polymeric cation-exchange resin that combines the outstanding properties of SHIMSEN Styra HLB with strong cation exchange functionalities. MCX is suitable for the enrichment and purification of basic compounds with pKa 2-10.
