Wakopak® Wakosil®-Ⅱ 5C22 is a HPLC column packed with high-purity silica gel, which is modified with a docosyl (C22) group and end-capped. Since the C22 packing agents have a longer alkyl group and a different retention time from the octadecyl (C18) packing agents, they offer superior separation characteristics for compounds with similar structure. Wakopak® Wakosil®-II 5C22 will provide better results when analyzing samples that are difficult to separate with conventional ODS columns.
