PRIMESIL AND TARGETSIL ,FLOWROSIL series HPLC column is designed for most LC method development, including a wide range of different phases (C18, C8, Phenyl, C4, C1, and CN as reverse phases, and CN, Silica, NH2, and Diol as normal phases). All the phases are made from monomeric organic silane to ensure exceptional batch-to-batch reproducibility and fast mass transfer. The different selectivity of primesil series phases allows customers to select the best column to achieve optimal separation.
