Reverse Phase

SHIMSEN Styra C18 is an octadecyl bonded silica cartridge and can retain target compounds by non-polar interaction. Highly endcapping of this sorbent inhibits cation exchange interaction caused by silanol groups, resulting in less adsorption of basic compounds. It is a good choice when non-polar interaction is needed.

SHIMSEN Styra Ph is a phenyl-bonded silica cartridge. It has the same non-polar interaction as C8, and also has the unique - electron pair interaction due to phenyl. It is a good choice for sample preparation when C8 could not provide the desired selectivity. And it has good selectivity for aromatic compounds with benzene ring.

SHIMSEN Styra C2 is an ethyl bonded silica cartridge and has weaker non-polar interation compared to C8. It is an excellent replacement for C8 when highly hydrophobic compounds are too strongly retained for effective elution. Highly endcapping of this sorbent inhibits secondary interactions caused by silanol groups, resulting in less adsorption of basic compounds. It is an excellent replacement for C8 and C18 when analytes are too strongly retained for effective elution.

SHIMSEN Styra C8 is an octyl bonded silica cartridge and has weaker non-polar interation compared to C18. C8 is an excellent replacement for C18 when highly hydrophobic compounds are too strongly retained for effective elution. Highly endcapping of this sorbent inhibits secondary interaction caused by silanol groups, resulting in less adsorption of basic compounds.

SHIMSEN Styra C18-U is an octadecyl bonded silica cartridge and can retain target compounds by non-polar interaction. The phase is non-endcapped which enhances retention of polar compounds.
