The column is suitable for the separation of derivatives of amino acids （A） and peptides （P）. The common procedures are summarized in the following table. If samples are not often analyzed, esp. DABSY

MLD packings （MLD = monolayer dense） are very stable solide supports, known in the literature as “mixed self-assembled monolayers （SAM）”. They can be used both for basic and acidic compounds in a re
