Hinshaw looks at causes and modes of premature column failure and at practices that ensure the longest possible column life.

The authors descibe the use of CE with condensation nucleation light-scattering detection to analyze three pharmaceutical analytes. Because the compounds lack adequate UV chromophores, they require a more sensitive means of detection.

The authors compare the chromatographic properties of embedded-carbamate-group bonded phases with those of their purely alkyl counterparts.

Guest author Cameron George discusses recent advances in purge-and-trap systems that enable considerable reduction in analysis times.
