Course objectives

Main objective is the knowledge of the analytical methods that can be applied in the field of geology, especially
- selected classical methods (gravimetric and volumetric determination of Si, Fe, Al, and S)
- modern instrumental methods (spectral methods /ICP, AAS, OES/, electro-chemical methods /Eh and pH measurements, polarography/, and chromatography /gas-, liquid-, gel-chromatography)
- some special methods (infra-red spectrometry, NMR, mass spectrometry, X-ray methods, neutron activation analysis)
Other objectives are
- practice in calculating of method accuracy/precision and error propagation
- practice of determination of mineral composition
- practice of analytical geochemistry arts in laboratory

Syllabus

• Using of analytical methods in geology: Specific problems at rocks analyses. Method applicability and testing. Rock standards. Analytical errors: behavior, influence of number operations. Precision and validity of the methods. Limits of detection and determination. Computations. The data handling and presentation.
• The sample preparation: Rock sampling. Crushing and grinding. Contaminations and composition changes. Quartering. Weighing. Rock dissolution in acids. Basic, acidic and oxidation fusion. Stock solutions, aliquots. Problems and errors.
• The choice of methods: Topical analytical methods. Destructive and non-destructive methods. Chemical and instrumental methods. Method suitability. Sensitivity, precision. The ratio precision/charge of determination.
• Chemical methods: Gravimetry (gravimetrical determination of high contents of S, Si, H2O, CO2). Volumetry (complexometric determination of high contents of Al, Ca, Mg, acidimetric determination of high contents of B, Si, oxidimetric determination of Fe(III), Fe(II)). Special operation (extraction, ion-exchange resins, ion-chromatography, ultrafiltration, centrifugation, masking).
• Instrumental methods: Principles, overview. Analytical signal. Standards. Method of calibration curve. Method of standard increment.
• Emission spectrometry: Total qualitative and semi-quantitative analyses of geological materials by OES. Determination of Li, Na, K, /Ca, Ag, Al/ by flame spectrophotometry. Determination of low concentrations of metals and some non-metals by ICP. Advantages, problems, applications. X-ray methods (energy and wave dispersion, total analyses of silicates by X-ray fluorescence, applications, advantages, electron microprobe).
• Absorption spectrometry: Atomic absorption spectrometry /AAS/ (Flame version, electro-thermic atomization /ETA/, determination of metal low concentration /Cu, Zn, Mg, Ca, Sr.../ by AAS, advantages, problems).

• Special methods: Neutron activation analyses. Infrared spectrometry. Mass spectrometry, Stable isotope determination. Analyses of mineral surfaces /AES, XPS, ERD, RBS, SIMS/. NMR and ESR methods.
• Electro-chemical methods: Electrodes. Monitoring of Eh and pH. Determination of elements /F, Ca, Na/ by ion-selective electrodes. Indication of equivalence point during titration. Continual monitoring. Polarography, anodic stripping voltammetry, limits of determinations, environmental applications. Tribo-polarograph. Capillary isotachophoresis, determination of anion low concentrations in waters.
