Chromatographic Separations

The term “chromatographic separations” refers to a group of analytical techniques used to separate the components of a homogenous mixture which are further detected, identified and quantitatively determined. The separation is due to different distribution between two phases: one stationary and one mobile.

Chromatographic techniques may include:

• Gas Chromatography (GC)
• Liquid Chromatography (LC)
• High-Performance Liquid Chromatography (HPLC)
• LC-MS
• LC-MS/MS
• LC-NMR
• 2D LC
• 2D GC
• GC-MS
• Capillary electrochromatography
• Supercritical Fluid Chromatography

Significant advances have been made over recent decades including instrumentation, as well as the materials used in stationary or mobile phases. All these advances follow the principles of Green Analytical Chemistry. Therefore, automation, speed and safety are of great importance.

Two-dimensional techniques hyphenated with spectroscopic techniques have improved the feature characteristics of established separation techniques making them the best analytical tool in the analysis of any kind of sample derived from various chemistry sectors as well as other scientific fields such as food science, veterinary medicine, biology, dentistry, archeology, forensics, pharmaceutical chemistry, medicine, environmental science, etc. To that end, major advances in separation science have led to significant findings in the above-mentioned scientific fields.

The aim of this Section of Separations is to illustrate the state of the art in chromatographic separations, and anyone working in the field is invited and welcome to contribute with a research or review article.

All manuscripts to be considered for publication in this Section will undergo a rigorous peer-review process, and decisions made will be based on recommendations from independent reviewers. With everyone's efforts, we hope to increase the impact of our contributions in the field of analytical chemistry.
