Protein/Peptide Columns

Amino Acid Analysis Columns

Most chromatographers have experienced problems retaining and separating polar compounds using conventional reversed-phase chromatography.  These difficult-to-analyze compounds either pass through the column unretained or, if retained at all, co-elute at the beginning of the chromatogram.  Waters AtlantisTM columns are designed for these types of challenging separations and are available in two chemistries: dC18 and HILIC sili…
