Today, headspace analysis is one of the most frequently used sampling methods in gas chromatography. This month's Milestones in Chromatography column discusses the technique's beginning and early uses, particularly in food science and in the determination of blood alcohol, and outlines the development of the first automated instrument integrating headspace sampling with a gas chromatograph.

Today, there is practically no gas chromatograph without a flame ionization detector. Besides the use of partition as the basis of separation and the open-tubular columns, it can be considered as the third most important invention in gas chromatography (GC). Most GC users take the flame ionization detector for granted, and very few are aware of its origin and the background behind its invention. This month's Milestones in Chromatography deals with this subject: the reasons that led to its invention, the development of the flame ionization detector, and its rapid triumph in becoming the universal detector in GC.

In this article, the authors review recent developments in the research of whole-column-imaging detection for capillary electrophoresis (CE). Whole-column-imaging detection was developed for capillary isoelectric focusing, for which it proved to be an ideal detector. Several whole-column-imaging detectors - including refractive index gradient imaging, UV-absorption imaging, and fluorescence imaging detectors - have been studied. The capillary isoelectric focusing UV-absorption imaging technique even has been commercialized. The development of whole-column-imaging detection itself facilitates CE studies in many directions such as in electrophoretic dynamics within narrow channels, new separation modes, and two-dimensional separations. Whole-column-imaging detection also finds application in capillary zone electrophoresis.
