Thermo Nicolet iS50 FTIR
Thermo Nicolet iS50 FTIR
The Thermo Nicolet iS50 Fourier transform infrared spectrophotometer is equipped to measure transmission, specular and diffuse reflection, diffuse transmission, and attenuated total reflection (ATR) in the mid-IR. Ranges vary for different accessories within 400 cm-1 to 7800 cm-1.
Its accessories include:
- Built-in diamond ATR for fast analysis of virtually any sample (minimal setup time)
- Transmission for solid samples
- Pellet press for making KBr pellets to measure powder samples in transmission mode
- Diffuse reflectance (DRIFTS) accessory for powder and small solid samples
- Multi-bounce specular reflection accessory (fixed angle of 70 degrees)
- Single reflection variable angle specular reflectance accessory (solid samples)
- Multibounce ATR attachment for dilute and low absorption solid and liquid specimens. Ideal sample size for solids is between 40 mm x 5 mm to 140 mm x 200 mm and for liquids a volume between 0.1 ml and 0.5 ml.
- IntegratIR® integrating sphere attachment can be used to measure diffuse reflectance or transmission of light-scattering and highly absorbing solid samples
