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 of ion-exclusion with 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.
