The many faces of packed column supercritical fluid chromatography--a critical review.

Supercritical fluid chromatography (SFC), which employs pressurized carbon dioxide as the major component of the mobile phase, has been known for several decades but has faced a significant resurgence of interest in the recent years, thanks to the development of modern instruments to comply with current expectations in terms of robustness and sensitivity. This review is focused on the recent literature, specifically since the introduction of modern systems but in relation to older literature, to identify the changing trends in application domains. Typically, natural products, bioanalysis, food science, and environmental analyses are all strongly increasing. Together with reduced extra-column volumes in the instruments, the advent of sub-2-μm particles and superficially porous particles in the stationary phases is favoring ultra-high-performance SFC (UHPSFC) allowing for improved resolution and faster analyses, but without the constraints of viscous liquids encountered in ultra-high-performance liquid chromatography (UHPLC). Hyphenation to mass spectrometry is also more frequent and opened the way to new application domains, and raises different issues from liquid chromatography mobile phases, especially due to decompression of carbon dioxide. It is also shown that the frontiers between SFC and HPLC are fading, as switching from one method to the other, even within the course of a single analysis, is facilitated my modern instruments. The present review is not intended to be exhaustive but rather giving a snapshot of recent trends in supercritical fluid chromatography, based on the observation of about 500 papers published in English-written peer-reviewed journals from 2014 to 2018.

Current trends in supercritical fluid chromatography

Among a number of gas analyzers, portable gas chromatography (GC) systems created by the integration of microfabricated components are promising candidates for rapid and on-site analysis of a number of complex chemical mixtures. This Feature provides a snapshot of the progress made in developing micro gas chromatography (μGC) systems in the last 4 decades. In particular, we discuss the development of microfabricated preconcentrators, separation columns, and detectors. Furthermore, we review different stationary phase materials used to coat the separation columns and the major efforts toward the development of an integrated μGC.

Micro Gas Chromatography: An Overview of Critical Components and Their Integration

The development of greener analytical techniques is a topic of great interest and in this context, supercritical fluid chromatography (SFC) is making an interesting comeback. The present review focuses on the latest developments of this technique. Improvements brought to the chromatographic systems and requirements to achieve full compatibility with columns packed with sub-2 µm particles (UHPSFC) are discussed. A thorough kinetic evaluation made using van Deemter representations, isopycnic and kinetic plots shows that performance achieved with state-of-the-art UHPSFC hardware and columns is comparable to that obtained in UHPLC. Orthogonal selectivity compared to reversed phase LC (RPLC) and extended selectivity modulation possibilities achievable in supercritical conditions using different stationary phase chemistries are presented. Finally, current applications of UHPSFC and its different hyphenation possibilities including mass spectrometry (MS) are also reviewed, in the hope of helping chromatography users to have a new look on the possibilities offered by this technique.
