FTIR (diamond ATR) technique. Spectral domain: 650-4000 cm-1. Qualitative and quantitative
identification of elements by FTIR. Infrared spectroscopy results in a qualitative and
quantitative analysis of every different kind of material. TG-FTIR coupled method - the TG/FT-IR technique is employed to study the evolution of the gases evolved during the thermal decomposition of solid materials. The FT-IR spectra of the gases evolved in situ, as they are generated are obtained by this technique. |

BET (Brunauer-Emmett-Teller) method. Surface characterization of materials (surface area, pore size, pore size distribution, average particle size, total pore volume) by surface area and pore size analyzer (BET). The BET method leads to a surface area parameter which allows to compare, classify and evaluate different samples and to take into account pores (micro-, meso- and macro pores), roughness and particle shapes by measurement. | Nova 2200e, Quantachrome | Dr. Cornelia MARINESCU aalcorinaa@yahoo.com |
