Equipment: FTIR-ATR Thermo Scientific Nicolet SummitX (compact)
Technique: Fourier Transform Infrared Spectroscopy
Contact Person: (UNINOVA): Rita Branquinho (ritasba@fct.unl.pt)
Description:
FTIR (Fourier Transform Infrared Spectroscopy) is an analytical technique used to identify organic, polymeric, and inorganic materials in powder, film and liquid samples. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties. ATR (Attenuated Total Reflectance) is an accessory that allows the same analysis with minimal sample preparation.
Specifications:
- Measurement in ATR mode in the range of 4500 – 400 cm-1.
- Detector (DTGS/KBr).
- Omnic Software allows spectra acquisition and identification of compounds & mixtures by comparison with spectra database with over 10000 spectra.
- ATR with diamond crystal with 3 mm diameter.
- Sample size: 1mL (liquids), 100mg (powders), >3 mm diameter (films and bulk samples)
- Sample type: liquids, powders, thin films (films < 2.5µm: standard c-Si wafers; films > 2.5µm: any substrate) and bulk samples (flat surfaces)
