| Analysis of Polymer Fillers and Colored Pigments |
Only one measurement per sample for complete MIR-FIR/THz spectral range, Additional information on inorganic filler materials in polymers, Simple polymer identification using dedicated FIR-MIR library |
| Spectral Range Applications |
MID IR region (4000-400 cm-1) provides information about composition and structure of organic compounds, FIR/THz region (below 400 cm-1) provides information about lattice vibrations and vibrations of functional groups with heavy atoms in inorganic ionic compounds |
| Bruker FM Technology |
VERTEX 70v coverage: 6000-50 cm-1 in single scan, INVENIO coverage: 6000-80 cm-1 in single scan, Complete characterization of modern polymeric materials, Ideal tool for polymer composite analysis |
| Filler Material Identification Examples |
Polystyrene filled with titanium oxide, Acrylonitrile butadiene styrene copolymer filled with antimony trioxide |
| Polymorph Differentiation |
Identifies sample crystallinity, Same chemical compound can exist in different solid forms (crystals, solvates, desolvated solvates, amorphous solids), Different polymorphic forms have different physical properties (solubility, melting point, particle size, dissolution rate, hygroscopicity) |
| Polymorph Analysis Benefits |
MIR region covers fundamental molecular vibrations for substance identification, FIR region covers backbone vibrations of larger molecules and intermolecular vibrations in crystal lattices, Complete informative MIR-FIR/THz spectral range in one measurement, Important for pharmaceutical companies for bioavailability assessment |
| Polymorph Example |
Different antibiotic sulfathiazole polymorphs |
| Inorganic Minerals Applications |
Geology and metal organic chemistry, FIR/THz region important for inorganic substances with vibrations of heavier atoms, Characteristic bands below 400 cm-1, High quality far IR spectra obtained simultaneously with standard MIR spectra without changing optical components |
| ATR Accessory |
Simplifies sample preparation compared to traditional polyethylene discs and Nujol mulls in transmission mode, Platinum ATR accessory with diamond ATR crystal ideal for far IR operation, All reflective optics, OPUS software contains advanced ATR correction function for comparing FIR ATR results with reference transmission spectra |
| Inorganic Minerals Example |
CaCO3 FIR ATR measurement |
