A sample that contains only a single enantiomer is enantiomerically pure.

Explanation:

For example, the specific rotation of (+)-tartaric acid is +12.7 °.

The specific rotation of its enantiomer is -12.7 °.

If you have a sample containing only one of the enantiomers, the sample is enantiomerically pure.
