Cogent Diol and Cogent UDA (undecanoic acid) are the latest additions to the MicroSolv range of stationary phases for high performance liquid chromatography (HPLC). Both columns are based on MicroSolv’s Type-C Silica and silica hydride surface chemistry.
Cogent Diol is a 4um diol bonded phase suitable for the reversed-phase or aqueous normal-phase (ANP) analysis of polar compounds and is LC-MS compatible. Columns show fast equilibration between gradient runs and can be successfully used in studies of pathways in human pathology.
Cogent UDA is a new selectivity phase where the silica hydride surface is bonded with an 11 carbon chain terminating in a carboxylic acid (undecanoic acid), giving the phase weak cation-exchange properties in addition to aqueous normal-phase (ANP). All the benefits of Type-C Silica, such as fast equilibration, precision, multi-mode and robust column-lifetime are maintained. The Cogent UDA columns have applications in metabolomics and have been used for the analysis of nucleotides.
