It may be somewhat audacious to claim that some methods in GCÃ-GC can be called non-classical - the technique has only been around for about 15 years and one might argue that this is not long enough to establish a suite of classical methods.

LC Troubleshooting

As I write this instalment of "LC Troubleshooting", I have just completed teaching a series of liquid chromatography (LC) method development classes to pharmaceutical scientists in India. As a parting gift, my host gave me a copy of Thomas Friedman's The World is Flat?.1 One central theme of this book is that the technology and skills for the science and information technology sectors are available around the world and are no longer the exclusive domain of the US and Western Europe.

The accuracy and precision of results in gas chromatography and other analytical techniques are highly dependent upon the sample and its preparation, the instrumentation, accessories and operating conditions, as well as operator skill and experience. For these reasons, accuracy and precision for a specific methodology can be expected to vary from one laboratory or operator to another. This month, we look at statistical analysis as a diagnostic tool.

In June of this year, the 30th meeting in the International Symposium in Capillary Chromatography series will convene in Dalian, People's Republic of China. The meeting promises to be a major celebration of separation science, and the separation science community has thrown its weight behind this initiative. The meeting is held under the auspices of the "International Organization for Promotion of Microcolumn Separations" and the "Chinese Academy of Science," with support from various organizations in China. Combined with the "4th Comprehensive Two-dimensional Gas Chromatography Symposium" and the "16th Chinese Symposium and Exhibition on Chromatography," the conference will offer many opportunities to present both international and regional accomplishments in chromatography. During the period of the symposia an exhibition will be held to showcase newly developed instruments and reagents from manufacturers around the world.
