Shim-pack GIST C18 has superior inertness, which improves

analysis precision and increases column stability. In addition, it

can be used to analyze strong ionic compounds and difficult to

absorb samples, which helps to obtain symmetrical peaks and

high reproducibility.

Furthermore, because of the new silica gel, Shim-pack GIST C18

is suitable for wider pH (1-10) analysis at a consistent

performance. This enables use of a silica-based column under

alkaline conditions.
