The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group.

1. A method of separating a compound of interest from a mixture, the method comprising: (a) providing the mixture containing the compound of interest;(b) introducing a portion of the mixture to a chromatographic system having a chromatographic column; and(c) eluting the separated compound of interest from the chromatographic column; wherein the chromatographic column has a stationary phase comprising or a mixture thereof;wherein X is a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof. 2. The method of claim 1, wherein the compound of interest is a lipid, vitamin, or polycyclic aromatic hydrocarbon. 3. The method of claim 2, wherein the lipid is a saturated or an unsaturated fatty acid, monoacylglyceride, diacylglyceride, triacylglyceride, phospholipid, sphingolipid or steroid. 4. The method of claim 2, wherein the vitamin is a water soluble vitamin selected from the group consisting of vitamin C, vitamin B, or derivatives or combinations thereof. 5. The method of claim 2, wherein the vitamin is a fat soluble vitamin selected from the group consisting of vitamin A, vitamin D, vitamin K, vitamin E, betacarotene, or derivatives or combinations thereof. 6. The method of claim 1, wherein the chromatographic stationary phase is adapted for supercritical fluid chromatography. 7. The method of claim 1, wherein the chromatographic stationary phase is adapted for carbon dioxide based chromatography. 8. A method for mitigating or preventing retention drift in normal phase chromatography, high-pressure liquid chromatography, solvated gas chromatography, supercritical fluid chromatography, sub-critical fluid chromatography, carbon dioxide based chromatography, hydrophilic interaction liquid chromatography or hydrophobic interaction liquid chromatography comprising: chromatographically separating the mixture using the chromatographic system comprising the stationary phase according to claim 1, thereby mitigating or preventing retention drift.
