Sisältö

Sisältö Ydinsisältö Täydentävä tietämys Erityistietämys
1. The theory of IR spectroscopy (vibrational modes, absorption mechanism). IR-spektroskopian teoria (molekyylin värähtelymuodot, säteilyn absorptiomekanismi) IR-spectrometer operational principles. Techniques and modes of measurements. IR-spektrometrin rakenne ja toimintaperiaate, näytteenkäsittelytekniikat. Characteristic spectra of the organic functional groups. Exercises in the spectra interpretation and structural identification of the organic compounds. Orgaanisten yhdisteryhmien spektrien tunnusomaiset piirteet, spektrien tulkintaharjoitukset ja yhdisteiden tunnistaminen  Interpretation of simple spectra  Interpretation of more complex spectra and structure elucidation based on spectral data 
2. Types of modern mass-spectrometers and their operating principles. Ionization methods. Nykyaikaisten massaspektrometrien tyypit ja niiden toimintaperiaatteet. Ionisaatiomenetelmät. Practice in MS analysis using ESI-TOF mass-spectrometer. MS-analyysin harjoitus käyttäen ESI-TOF massaspektrometria.  Resolution and accuracy of MS-analysis. Applicability of different mass-analyzers and ionization methods. MS-analyysin erotuskyky ja tarkkuus. Eri massa-analysaattorien ja ionisaatiomenetelmien soveltuvuus.   
3. Differential scanning calorimetry (DSC). Lectures (266 pages): Definitions and main principles behind the method and measuring technique. Instrumentational features. Applications. Interpretation of the basic dynamic and isothermal DSC-curves. Laboratory: How to carry out the DSC-measurements and evaluate the basic DSC-curves, starting from the switching on the two available instruments and preparing the samples, and ending with shutting the DSC-modules down.  -Fixed instrumental parameters and parameters tunable by the user. -Interpretation of the complicated phenomena measured with DSC. -Difference between calibration and checking of the calibration in principle. -Checking of the calibration in practise.  Special applications and their measurements and evaluation of the data: Kinetic methods and programs. Temperature modulated DSC (multifrequency TOPEM and single-frequency ADSC). Differential photocalorimetry (UV-DSC). (Pressure and vacuum applications.)  
4. Thermogravimetric Analysis (TGA). Lectures (18 pages): Definitions and main principles behind the method and measuring technique. Simultaneous differential thermal analysis (SDTA). Applications. Interpretation of the TGA-curves. Laboratory: How to carry out the TGA-measurements and evaluate the content from the weight loss curves, starting from the switching on the instrument and preparing the samples, and ending with shutting the TGA down.  Interpretation of the TGA-curves: conversion (extent of reaction).  Interpretation of the TGA-curves: derivative TGA. 

Ohjeita opiskelijalle osaamisen tasojen saavuttamiseksi

The grade will be based on an exam. Each block will have an intermediate exam. If the student demonstrates thorough understanding of the core content, s/he may pass the course with the grade 3. In order to achieve higher grade, the student should demonstrate competency in the points specified as "Complementary knowledge" and "Specialist knowledge". The total course grade will be based on the average of intermediate grades.
