Annotation -
The aim of the subject is to provide the students with firm and sufficiently wide theoretical and methodological fundamentals for pursuing (in a rational way) instrumental analysis of inorganic and organic substances. The teaching is focused on the explanation of theoretical aspects of instrumental methods and putting the accent on problem-solving tuition. In practical training individual approach of students to solving analytical problems is required.

Learning outcomes -

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;
