Materials Characterization

Thermogravimetric Analysis (TGA): TA Instruments Q500 (Unvailable at the moment)

TGA is a technique for determining the thermal stability of materials, such as polymeric composites and pharmaceutical compounds.

  • Operation temperature: ambient to 1000 oC
  • Gas atmosphere: Air or N2
  • Heating rates: 0.1 to 100 oC/min
  • Sample weight: 5 to 1000 mg
  • Sample pan: Platinum 50 uL

Differential Scanning Calorimetry (DSC): Mettler-Toledo DSC1

DSC is a technique for measuring heat flow of phase changes in solid or liquid states.

  • Operation Temperatures: -90°C to 600°C
  • Gas atmosphere: Air or N2
  • Heating rate up to 100K/min
  • Cooling rate up to 50K/min
  • Sample weight: 2 to 10 mg
  • Sample pan: Aluminum 40 uL
  • Isothermal, dynamic and TOPEM experiments

Fourier transform near-infrared spectroscopy (FT-NIR): PerkinElmer Spectrum Two N FT-NIR

NIR spectra comprise broad bands arising from overlapping absorptions corresponding mainly to overtones and combinations of vibrational modes involving CH, OH and NH chemical bonds. FT-NIR is a technique for determination of the concentrations of constituents such as water, protein, fat and carbohydrate in plant and animal tissues.

  • InGaAs detector enables to collect data over a total range of 10,000 to 4,000 cm-1
  • The Near Infrared Reflectance Module (NIRM) with sample spinner allows for collecting diffuse reflectance spectra of solids, granules, pastes, powders and turbid liquids
  • Heatable Transmission Module allows for easy elevated temperature measurements on samples

Fourier transform infrared spectroscopy (FT-IR): Bruker Tensor 27 FT-IR

FT-IR is a technique for identifying organic or inorganic materials by measuring the absorption of infrared radiation on the sample material versus wavelength.

  • Spectral range: 4000 to 400 cm-1
  • ZnSe MIRacle ATR allows for direct analysis of solids, liquids and powders
