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. It also includes an FT-Raman measurement module with a 500 mW 1064 nm excitation source and an InGaAs detector.

Its accessories include:

• FT-Raman module for measurement of bulk, powder, and liquid samples, equiped with XYZ sampling stage; USB video camera; 9 and 48 well sampling tray; microscope slide holder; and vial holders. It uses a 1064 nm laser for excitation, avoiding the presence of fluorescence on the Raman spectra for most samples.
• 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
