WebNormal phase SFC and LC columns for efficient reliable separations. Normal phase SFC (supercritical fluid chromatography) and LC (liquid chromatography) columns offer exceptional efficiency and reliability in both separation modes. Unique polar stationary phases offer a broad range of orthogonality to master most challenging isomer … Web1 de jul. de 2012 · If buffer concentration problems are suspected, double the concentration and see if this fixes the peak shape. After the mobile phase is eliminated as the problem source, look to the column. If a guard column is in use, remove it and make an injection. If the peak is OK after that is done, the guard column has failed.
