HPLC Method for Octylphosphonic acid on Newcrom A by SIELC Technologies
Octylphosphonic acid (OPA) is a surfactant with the chemical formula C8H19O3P. It can be used to synthesize self-assembled monolayers (SAMs), polymeric matrices, and as a coating for super-resolution microscopy.
Using a Newcrom A mixed-mode column and a mobile phase consisting of water and acetonitrile (MeCN) with a formic acid buffer, OPA can be retained, measured, and analyzed. This analysis method can be used in conjunction with charged aerosol detection (CAD).
