Determination of thermodynamic properties by Supercritical Fluid Chromatography.
Journal of chromatography. A, 2004Co-Authors: Michal RothAbstract:This survey attempts to summarise thermodynamic applications of Supercritical Fluid Chromatography (SFC) with an emphasis on the results published during the last 10 years. In addition to a review of thermodynamic measurements by SFC, it contains brief sections on instrumental considerations and on the sources of auxiliary information needed when processing the retention data.

Diffusion and thermodynamic measurements by Supercritical Fluid Chromatography
Journal of Microcolumn Separations, 1991Co-Authors: Michal RothAbstract:Applications of Supercritical Fluid Chromatography (SFC) to physicochemical measurements are reviewed. Emphasis is laid on the determination of binary diffusion coefficients at infinite dilution of solutes in Supercritical solvents, and on actual or potential applications of SFC to the measurements of thermodynamic quantities in dilute, binary, Supercritical mixtures. Physicochemical measurements emerge as a specific application field of SFC with many links to transport phenomena and to molecular thermodynamics of Fluid-phase equilibria.

Thermodynamics of retention in Supercritical Fluid Chromatography: a refined model
The Journal of Physical Chemistry, 1990Co-Authors: Michal RothAbstract:Expressions have been obtained giving the pressure and temperature derivatives of the solute retention in Supercritical Fluid Chromatography (SFC) in terms of measurable quantities. Unlike most previous thermodynamic models, the pressure- or temperature-induced changes in composition and amount of the stationary phase («swelling») are explicitly included

Forensic applications of Supercritical Fluid Chromatography - mass spectrometry.
Journal of chromatography. B Analytical technologies in the biomedical and life sciences, 2018Co-Authors: Volodymyr Pauk, Karel LemrAbstract:Abstract Achievements of Supercritical Fluid Chromatography with mass spectrometric detection made in the field of forensic science during the last decade are reviewed. The main topics include analysis of traditional drugs of abuse (e.g. cannabis, methamphetamine) as well as new psychoactive substances (synthetic cannabinoids, cathinones and phenethylamines), doping agents (anabolic steroids, stimulants, diuretics, analgesics etc.) and chemical warfare agents. Control of food authenticity, detection of adulteration and identification of toxic substances in food are also pointed out. Main aspects of an analytical workflow, such as sample preparation, separation and detection are discussed. A special attention is paid to the performance characteristics and validation parameters of Supercritical Fluid Chromatography-mass spectrometric methods in comparison with other separation techniques.
