Retention of carbohydrates on silica and amine-bonded silica stationary phases: application of the hydration model

Hydrophilic interaction chromatography of small metal species in plants using sulfobetaine‐ and phosphorylcholine‐type zwitterionic stationary phases

“…An influence of the hydration number on HILIC retention has been shown already for carbohydrates [4]. This is reflected also by our data on carbohydrates, e. g., it explains the much higher retention time of inositol in comparison to glucose (see Table 1).…”

Solvent structures of mixed water/acetonitrile mixtures at chromatographic interfaces from computer simulations

“…Earlier work on the separation of sugars in the reverse phase on propyl amine columns came to similar conclusions. 34,35 Based on the current simulations, the existence of stable water molecules near the Si surface is a valid proposal. However, the mixtures used here (50/50) are probably still too water-rich to make direct contact with the results from HILIC experiments.…”

“…2e and f). This is also the water concentration range where the stationary phases start to become saturated and the enrichment levels off on underivatized and aminopropyl silicas, according to Verhaar and Kuster [34] and Nikolov and Reilly [36]. This finding could very well be taken as an indication of liquid -liquid partitioning.…”
