Vorschrift

Example 1 was repeated with the difference that the sample to be tested was a glutamine of unknown enantiomer composition, the comparison samples were (RS)-, (R)-, and (S)-glutamine, and the mobile phase was a mixture of methanol, water, acetonitrile, and tetrahydrofuran in a 1:1:2:2 ratio by volume. In this case, the (R)-glutamine gave a spot with an Rf -value of 0.70 and the (S)-glutamine gave a spot with an Rf -value of 0.62.
