Chromolith^® RP-8 endcapped monolithic silica column offers high throughput, extremely long column lifetime, lower matrix sensitivity, and added column performance by column coupling. Chromolith RP-8 endcapped column is based on a high-purity silica to reduce the negative effects of trace metals. It is chemically modified with n-alkyl chains with a high ligand density and then fully endcapped in order to reduce the effect of unmodified silanol groups. In comparison to a Chromolith RP-18 endcapped column, a Chromolith RP-8 endcapped column offers a better retention for hydrophobic compounds. The Chromolith RP-8 endcapped column is available in the dimension 100-4.6 mm.
