Ion-Pair Chromatography and Related Techniques

Teresa Cecchi earned a Ph.D. in chemistry from Camerino University in Italy in 1997. She focused on environmental chemistry at Institute Fresenius Gruppe, Germany and served as a consultant to food chemistry laboratories. After working as a researcher at Camerino University on the SUPREME project titled "Pigmentation in South American Camelids," she concentrated on ion pairing chromatography; her major research interests encompass many aspects of this technique including retention modeling, unusual analytes such as zwitterions, and application of this technique to non-separative functions. Dr. Cecchi’s career and studies also span the fields of food packaging chemistry, natural dyes, electrochemistry, and the antioxidant activities of nutraceuticals. She acted as the organizer of a research group at Istituto Tecnico Industriale Statale (It is) Montani in Italy and taught as a contract professor at La Sapienza University in Rome. She is currently a contract professor on the Faculty of Science and Technology at Camerino University, teaching master’s level courses in chemistry and advanced chemical methodologies and a professor of analytical chemistry at ITIS Montani. Dr. Cecchi is also involved in "Teaching of Experimental Sciences" and "Scientific Master Degrees," two projects whose purposes are, respectively, to improve the methodologies of teaching physical sciences, and to encourage students to study scientific subjects. She is the author of over 50 research articles, reviews, congress lectures, and other communications and was the corresponding author of an article that received an award from the Italian Research Evaluation Panel.

"… provides a broad coverage of the subject of IPC with regard to theoretical features, the parameters influencing the results and the applications. The reader will find a discussion of all aspects of IPC, beginning with the theoretical basis of this technique and its retention mechanism. The author introduces to the reader all the issues connected with stationary phases, ionpair reagents, organic modifiers, the pH of the eluent, temperature, and various detection techniques which may be used in IPC. One can also find much practical advice on how to start with IPC and how to improve results by the use of IPC."—Analytical and Bioanalytical Chemistry, April 2012
