High Performance Liquid Chromatography (HPLC) Method for Analysis of CBD, CBN, delta-9 THC, delta-8 THC
Octylphosphonic acid (OPA) is a surfactant that 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).

Application Column
Newcrom A
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.
