Newcrom Mixed-Mode HPLC Columns from SiELC
Newcrom HPLC columns from SiELC are a new generation of mixed-mode columns based on moving the charged embedded functional groups as far from the silica gel surface as possible. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reversed phase column with low silanol activity.
