During the course of Analytical Chemistry the student will learn some of the most advanced analytical techniques. The most important instrumental methods will be covered as well, in particular those for modern and advanced biological applications. Technical details and applications will be also considered. Particular emphasis will be given to chromatography, mass spectometry and spectroscopy.

Units of measurement. Preparation of solutions and dilutions. Validation of analytical methods: The error of measurement: Significant figures. Errors and their detection and minimization. Precision and accuracy. Calibration. Pearson coefficient. Method of least squares. Standardization procedures. Sample preparation techniques. Extraction and preconcentration. Recovery efficiency. Chromatographic methods: distribution coefficient. Column chromatography. The chromatogram and the chromatographic parameters. Chromatographic resolution and efficiency. Band broadening. Van Deemter equation. High performance liquid chromatography : stationary phases and mobile phases. Types of columns. UHPLC and other high efficiency techniques. Separation mechanisms: absorption, distribution, ion exchange, size exclusion. Ion chromatography. HPLC injector. HPLC detectors: RI, UV-Vis, fluorescence, electrochemical detectors.Mass Spectrometry: ionization techniques: electronic ionization, chemical ionization, electrospray ionization (ESI). General features of a mass spectrum. Mass spectrometric resolution. Fragmentation characteristics. Isotopic cluster. Mass analyzer: quadrupole (Q), ion trap (QIT), time of flight (TOF). Chromatography-mass spectrometry coupling, HPLC-MS. instrument configurations and operating modes. Using the mass spectrometer in the analytic field: SIM, Scan.

Assessment

Written test with open questions.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
