● Fourier-transform infrared spectroscopy (Spectrum Two by Perkin Elmer) is a technique used to analyse the structure of material. FTIR is equipped with ATR (Attenuated Total Reflectance) accessory which simplifies the analysis of solid, powder, pastes, gels and liquids. FTIR is also equipped with microscope.
● Gas chromatography (Clarus 690 by Perkin Elmer), is used for separating and analyzing compounds that can be vaporized without decomposition. GC is equipped with Mass Spectrophotometer (CLARUS SQ8C MS 120/230V (EI/CI) & Headspace.
FITR is used for structural identification of the material. FITR microscope is used to observe, record & identify the contaminants in film & textile material. GC is used for testing the material for its purity & to resolve the quality issues. We use the mass spectrum to analyse the structure of unknown material. Headspace is used to extract the volatile of interest from the complex mixture of solvents & solid matrix which then transferred to the GC for analysis. We used this technique to analyse monomers in polymers, residual solvents & additives in the formulations.
