Cílem výuky je poskytnout studentům pevný a dostatečně široký teoretický a metodický základ pro metody instrumentální analýzy kvalitativní a kvantitativní, a to jak anorganických tak i organických látek. Těžiště výuky spočívá ve výkladu teoretických základů instrumentálních metod analýzy. V praktických cvičeních je kladen důraz na samostatný přístup studentů k řešení analytických problémů vybraných instrumentálních metod.

The Instrumental Methods course builds on the knowledge and skills acquired in the subjects: Physical Chemistry and Analytical Chemistry. After completing the course, students will be able to use the following terms in the correct context towards the analytical evaluation of inorganic and organic substances using instrumental methods: spectrophotometry in the visible and UV region, potentiometry and its use for the evaluation of titration determinations, polarimetry for determining the content of optically active substances, identification of organic substances using optical techniques (IR and Raman spectrometry), use of melting point for identifying organic compounds, thin layer chromatography (design, detection, composition of stationary and mobile phases), high-performance liquid chromatography (normal and reverse phase, pH adjustment of the aqueous component of the mobile phase in reverse mode, detection), gas chromatography (capillary and packed columns, elution method, detection). Learning outcomes: Based on the acquired knowledge and skills, students will: explain the procedure for determining an organic substance using spectrophotometry in the visible region, including derivatization, optimization of spectrophotometric determination, measurement of the calibration curve and its evaluation and applications for determining the content of a substance in the visible region of the spectrum; explain the procedure for potentiometric indication of the equivalence point and various types of titration determinations, including the selection of an electrode system, evaluation of the titration curve and calculation of the content of the substance being determined; define polarimetry as an instrumental method for assessing the purity/content of an optically active organic substance, including the procedure for measuring and calculating the content using specific optical rotation; explain the procedure for identifying an organic compound using various types of spectral methods, compare their approach and the information obtained, differences in the principle of these techniques, evaluate spectra and identify an organic compound; explain the principle of identifying a compound by determining the melting point of this compound and its derivative; explain the principle of thin-layer chromatography using silica gel as a stationary phase, describe the procedure, various methods of detection and evaluation of a chromatogram for identifying organic substances and their derivatives; explain the principle of separation of analyte mixtures by HPLC, describe the system, characterize retention mechanisms, stationary and mobile phases in two basic chromatographic modes, describe detectors in HPLC and evaluation of chromatograms using an external or internal standard to identify and determine the content of organic substances in mixtures; define for which substances GC is used for separation, explain the difference between LC and GC with regard to the stability of substances, temperature regime, and the principle of basic types of detectors.
