Fourier-Transform Infrared Spectroscopy (FTIR)

Model: Thermo Scientific Nicolet iS20

Location: 014 Brauer Hall

Description: FTIR is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.

Capabilities:

• Range: 400-5000 cm^-1
• Resolution: 0.125 cm^-1
• Detector Type: Nexus DTGS with a KBr Window.
• Diffuse Reflectance – The diffuse reflection technique lets you analyze highly light-scattering solids that are difficult to analyze using transmission techniques. The technique is also useful when the sample, usually a powder, must be analyzed without modification. This accessory lets you analyze a wide variety of sample types and features integral sample cups for convenient, fast sampling.
• Attenuated Total Reflection – The technique is used to measure the IR spectra of surfaces or of material that are too thick or strongly absorbing to be analyzed by more traditional. This is a horizontal ATR accessory with high stability, complete purge capabilities, tool-free alignment and high performance specifications. It includes integral purge tubes that seal the accessory from the atmosphere, and a cast aluminum body for exceptional stability.
• Sampling capability for liquids, solutions, gels, pastes, powders, thin films and solids.

Typical uses:

• Identify bulk or surface contamination on or in a material (e.g., particles, fibers, powders, or liquids) for example testing water quality and analyzing soil to assess pollution levels.
• Unknown material identification and verification (e.g., films, solids, powders, or liquids); copolymer and blend assessment; additive identification and quantification; molecular degradation assessment; surface active centers (adsorbents); reaction kinetics; solutes concentration
• Ideal to identify chemical origins of material failure and an analytical tool for both routine quality control analysis.
