Description

General description

Sodium dodecyl sulfate (SDS) is commonly used asan ion pair reagent in ion pair chromatography.

Application

Sodium dodecyl sulfate can be used as an ionpair reagent and disperser agent in ion pair-based surfactant-assisteddispersive liquid–liquid micro extraction (IP-SA-DLLME) method for chromiumspeciation analysis.
