Journal of Chromatographic Science logo Preston Publications logo

The Journal of Chromatographic Science (JCS), published 10 times a year, is an international publication providing research papers describing in-depth information on all chromatographic techniques, applications, sample preparation methods, systems problems solving and more. Editorial quality is assured by a thorough and vigorous peer-review system.

Articles provide discussions of practical applications of gas chromatography (GC), liquid chromatography (HPLC), thin layer chromatography (TLC), size-exclusion, supercritical fluid chromatography (SFC), capillary electrophoresis (CE), spectrometry, hyphenated techniques (GC-MS, LC-MS, GC-FTIR), and more.

In addition to the articles, there is a new products, literature department.

Worldwide readership includes scientists, educators, researchers, and analytical chemists actively involved in the use of chromatography.
