Sodium dodecyl sulfate, or sodium lauryl sulfate, is a surfactant used in cleaning and hygienic products. It has a twelve carbon hydrophobic tail attached to a polar sulfate. Dodecyl sulfate can be retained on Newcrom B and BH columns in under 10 minutes with an MS-compatible mobile phase.

Application Column
Newcrom B
The Newcrom columns are a family of reverse-phase-based columns. 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 reverse-phase column with low silanol activity.
