HPLC Determination of Sodium Dodecyl Sulfate on Primesep B4 Column

HPLC Determination of Sodum Dodecyl Sulfate

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 Primesep B4 column in under 5 minutes with an MS-compatible mobile phase. Primesep B4 is a short carbon chain reverse-phase (RP) mixed-mode column with embedded basic ion-pairing groups.
