Description

General description

Sodium dodecyl sulfate (SDS) is commonly used asan ion pair reagent in ion pair chromatography.[1]

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a surfactant to enhance catalysis.  Click here for more information.

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.[2]
