Cannsep A is a reverse-phase analytical column with embedded strong acidic ion-pairing groups

This stationary phase retains neutral cannabinoids by reverse-phase mechanism.
Acidic cannabinoids such as Tetrahydrocannabinolic acid (THCA) and Cannabidiolic Acid (CBDA) will be subject to ion-exclusion interactions with the negatively charged stationary phase of Cannsep A.
Mobile phases can be selected to be compatible with low UV detection with phosphoric or sulfuric acid as a modifier.
Alternately, the LC-MS and preparative chromatography compatible mobile phase can be use with formic acid as a modifier.
