Fluorolog 3 is a unique, modular system for the measurement of steady-state fluorescence and phosphorescence spectra of liquid and solid samples including non-transparent materials. The spectrophotometer is very sensitive and flexible to be used for various types of fluorescence or phosphorescence measurements in emission, excitation and synchronous modes. The set is able to measure in ultraviolet, visible and near-infrared regions.

  • Measurement within a spectral region 200-1600 nm
  • Adjustable spectral slit individually for excitation and emission

Modules and accessories:

  • Motorized, software-controlled excitation and emission polarizers for the measurements of fluorescence anisotropy, and linearly-polarised fluorescence spectra
  • Topped-flow accessory for the measurements of reaction kinetics for the fast reactions
  • Integral sphere for the automatic measurements and determinations of photoluminescence quantum yields
  • Autotitrator for the spectrophotometric titrations
  • Accessory for constant temperature measurements using a Peltier type thermostat
  • Front face configuration for the measurement of non-transparent samples
  • Phosphorescence measurements using a flash lamp
  • special detector for the measurement in a near infrared region


FTIR spectrometer Nicolet 6700 (Thermo Scientific)

Contact: RNDr. Jana Madejová, DrSc. e-mail: jana.madejova@savba.sk

High research-grade Fourier Transform Infrared (FTIR) spectrometer allows measurement of the spectra in the near (12000-4000 cm-1), middle (4000-400 cm-1) and far (400-50 cm-1) infrared regions. The instrument is used for measurement of the spectra of solid (powders, films, etc.), liquid (suspension, dispersion,) or gaseous samples. This method is very convenient for qualitative or semi-quantitative analysis of materials of various types, e.g. to follow purity of chemical compounds, mineralogical composition of the rocks, in the various branches of material research to characterize materials, to follow their properties, interactions and changes upon material processing. Except of conventional transmission techniques, the FTIR spectrometer Nicolet 6700 is equipped with Smart Accessories for reflectance technique including:

  • Orbit diamond single bounce ATR (attenuated total reflection),
  • Specular ATR,
  • Diffuse Reflectance and Near-IR UpDRIFT accessory and environmental chamber allowing experiments under controlled temperature (up to 900 °C) and/or under controlled gaseous atmosphere.

Inductively coupled plasma optical emission spectrometry (ICP-OES), is an analytical technique used for the detection of metals. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic for a particular element.
