Methods and Facilities

A variety of devices and equipment for sample preparation and analysis are available in our lab. Depending on the aim of the analysis sample is lyophilized, dried, chemically/mechanically decomposed, mineralized in a microwave oven, pre-concentrated (vacuum or SPE), fractionated, dry ashed, etc.  Simpler spectroscopic methods, such as UV-vis, fluorescence, and infrared spectroscopies, are used to characterize transition metal ions, conjugated organic compounds, and biological macromolecules. Nuclear magnetic resonance (NMR) and infrared (FTIR) spectroscopies are applied to investigate and identify the structure of organic compounds, macromolecules, and polymers.

Also, powerful analytical apparatus for trace level and macro element analysis (AASG, AASF, elemental analyzer), several gas- and liquid chromatographs with different detection modes (UV/DAD, RID, fluorescence, MS/MS) are available for determination of the composition of organic and inorganic substances in wide concentration range. High-resolution mas-spectrometric measurements are carried out by using an ESI-Q-TOF mass spectrometer.

Approximately 300 m2 of laboratory space is available at TalTech Department of Chemistry and Biotechnology for analytical experiments and related chemistry
