FTIR Spectroscopy

Exploring FTIR Technology: Unlocking the Power of Infrared Spectroscopy

Fourier transform infrared spectroscopy (FTIR) is a foundational analytical technique used to identify molecular structures in a wide range of materials, including solids, liquids, and gases. It offers valuable insight for industries requiring non-destructive analysis, such as pharmaceuticals, environmental science, forensics, and material research. FTIR systems are known for their sensitivity, selectivity, and ability to deliver high-throughput results with minimal sample preparation.

Shimadzu offers a versatile suite of FTIR instruments, including the compact IRSpirit-X, the mid-level IRXross, and the high-performance IRTracer-100. Each platform is tailored to specific workflows while maintaining Shimadzu's hallmark precision and reliability.

Key Performance Features Across the FTIR Range

Exceptional Sensitivity and Resolution Top-tier instruments like the IRTracer-100 offer an S/N ratio of 60,000:1 and a resolution of 0.25 cm⁻¹, making them ideal for trace-level analysis. Whether identifying low-concentration contaminants or capturing subtle spectral differences, Shimadzu systems provide accuracy without compromise.

Dynamic Interferometer Stabilization instruments incorporate dynamic alignment mechanisms and dehumidifiers to ensure long-term stability. This is essential for reproducible data and reliable quantitative analysis, particularly in humidity-sensitive environments.

Integrated and Intuitive Software LabSolutions IR software simplifies FTIR operation with automated workflows, customizable macros, and a comprehensive spectral library. Designed for both novice users and experienced analysts, it supports scanning, data processing, quantitation, reporting, and regulatory compliance.

Everyday Laboratory Needs

Designed for labs with limited bench space, the IRSpirit-X series provides flexibility with vertical and horizontal sample placements and built-in accessories.

Common FTIR Analysis Techniques

Transmission Spectroscopy

Ideal for thin films, liquids, and gases, transmission FTIR measures the direct passage of infrared light through the sample. Instruments such as the IRXross and IRTracer-100 excel in this traditional yet powerful approach.
Attenuated Total Reflectance (ATR)

ATR is a popular method for analysis of solids, viscous materials, powders, and liquids with minimal sample preparation. By using a high-refractive-index crystal, the IR beam generates an evanescent wave that interacts with the sample. ATR accessories are compatible across Shimadzu systems and benefit from automated correction functions within LabSolutions IR.
Diffuse Reflectance (DRIFTS)

This method collects scattered IR light from powdered or inhomogeneous samples. Ideal for surface chemistry, catalyst research, and heat-treated samples; and it avoids the need for pelletizing the sample.
Specular Reflectance (DRIFTS)

Used for reflective or coated samples. This technique analyzes the light reflected at the same angle as the incident beam, allowing the study of thin films or multilayer coatings.
