Overview
SimpyLab C18 solid-phase extraction columns can be divided into three types: capped C18 solid-phase extraction columns, unsealed C18 solid-phase extraction columns, and hydrophilic C18 solid-phase extraction columns. The $r $nC18 (capped) solid-phase extraction column is packed with octadecyl silica gel and retains non-polar compounds through strong hydrophobic interactions. This filler can retain most of the organic matter and is widely used in fields such as environment and food safety. (Equivalent to Waters Sep Pak tC18/C18, Agilent Bond Elut C18, Supelco S)

C18N(Unfolded ends are filled with octadecyl silica gel, which mainly retains non-polar compounds through hydrophobic interactions. In addition, its residual silanol groups provide additional polarity retention ability. C18N is a universal stationary phase that can retain both polar and non-polar compounds.

C18A(Hydrophilic) using octadecyl silica gel as a filler, non-polar compounds are extracted from aqueous solutions through hydrophobic interactions. The fully covered surface is hydrophilic modified, making the stationary phase easily wetted by water, maintaining the carbon chain upright in the aqueous mobile phase, and improving the water resistance of the silicone matrix. |
Good stability, can be purewaterFor the mobile phase Provide additional retention energy for polar compounds力 |
