Chiral separation screening has become a widely accepted approach for the rapid identification of an appropriate chiral stationary phase for use in more focused enantioseparation optimization. A set of extended screens encompassing various chromatographic modes using HPLC and SFC is presented.

This instalment describes more popular myths or half-truths in UHPLC and provides data that contradict or even repudiate some of these commonly held beliefs.

Questions about how practical proposed gas chromatography (GC) method changes are often come up during optimization for speed and resolution, or while converting to a different carrier gas. Related objective measurements such as the optimum practical carrier gas velocity were defined more than 40 years ago. This instalment reviews such metrics in the light of their relevance to today's GC challenges.

In the final part, the top 10 HPLC and UHPLC column myths are presented and attempts are made to demystify them by offering some evidence that they are untrue. This part will feature myths five to one.

There are many ways to improve retention or selectivity in reversed-phase HPLC and knowledge of the key eluent variables to achieve this is essential reading.

Two different methods of calculating the LLOQ disagree. Which, if either, is correct?
