## Abstract The threeโ€component mobile phase, methanolโ€“acetonitrileโ€“water, has been frequently used for the separation of natural products in complicated herbal extracts by reversedโ€phase liquid chromatography, especially when twoโ€component solvent systems do not work.

## Abstract Supercritical fluid chromatography has primarily been applied to relatively nonpolar analytes, even when polar organic solvents are used as modifiers. Here, we show that low levels of volatile ammonium salts as mobileโ€phase additives allow the elution of polar and even ionic organic mat
