FTIR Series and Infrared/Raman Microscope Accessories

Importance of the Topic

Fourier transform infrared (FTIR) and Raman spectroscopy are core techniques in analytical chemistry for material identification, structural analysis and quality control. Advances in accessory design extend their applicability to a broad range of sample types, enabling non-destructive measurements with minimal sample preparation, high throughput and improved sensitivity. Such flexibility is critical in research, industrial QA/QC, pharmaceuticals and materials science.

Study Goals and Overview

This document presents a comprehensive catalog of accessories developed for Shimadzu FTIR systems (IRTracer-100, IRPrestige-21, IRXross, IRAffinity-1, IRSpirit, FTIR-8000) and infrared/Raman microscopes (AIMsight, AIRsight). The goal is to guide users in selecting optimal attachments—covering attenuated total reflection (ATR), specular reflectance, reflection absorption spectroscopy, diffuse reflectance, transmission cells, NIR measurement and microscopy—to meet diverse analytical challenges.

Methodology and Instrumentation Used

Accessory selection is aligned with sample physical forms and measurement modes:

• ATR attachments: Single-reflection (QATR, MIRacle, GladiATR) and multi-reflection (HATR, ATR-8000/8200) prisms (diamond, ZnSe, Ge, KRS-5) for films, powders, liquids and rubbers.
• Reflectance: Specular reflectance and reflection absorption spectroscopy using SRM-8000 and RAS-8000 series with grid polarizers for thin coatings on metals.
• Diffuse Reflectance: DRS-8000/8010ASC with Kubelka–Munk conversion for powders and micro/trace solids.
• Transmission Cells: Demountable, sealed, fixed-thickness cells, diamond cell and KBr pellet dies for liquids, mulls and solid films.
• Gas Cells: Short-path (5/10 cm) and long-path gas cells for trace and low-concentration gas analysis.
• Microscopy: Infrared transmission, reflectance and ATR with AIMsight, infrared/Raman microanalysis with AIRsight, up to 3 μm spatial resolution.
• NIR: Near-infrared accessory kit, diffuse reflectance UpIR A and integrating sphere IntegratIR A for rapid qualitative and quantitative analysis of powders, liquids and solids.

Main Results and Discussion

The accessory lines provide measurement flexibility across the IR spectrum (4000–200 cm⁻¹) to the far-infrared (240 cm⁻¹), with specialized detectors (DLATGS, MCT, InGaAs). Automatic sample changers (ASC-8000T, DRS-8010ASC, Sample Switcher 21) and control software (LabSolutions IR, BASIC, SPECTROMACRO) enable high-throughput workflows. Accessory recognition streamlines setup and ensures reproducibility. Microscopy attachments with objective mirrors, pressure sensors and polarizers support contaminant analysis and molecular orientation studies.

Benefits and Practical Applications

Key advantages include:

• Non-destructive analysis with minimal sample prep.
• Wide applicability to solids, liquids, gases, films, powders and micro-areas.
• High spectral accuracy, multiplex measurement and rapid scanning for kinetic studies.
• Automated sample handling for routine QA/QC and high-volume screening.
• Enhanced sensitivity for trace analysis via ATR and long-path gas cells.
• Integrated IR/Raman capabilities for complementary structural information.

Future Trends and Potential Uses

Future developments will focus on further miniaturization, integrated multi-technique platforms, in-situ and real-time measurements, AI-driven spectral interpretation, hyper-spectral imaging and expanded hyphenation with chromatography and mass spectrometry. Innovations in fiber-optics, ambient-pressure microscopy and portable FTIR/Raman systems will broaden field and process analytics.

Conclusion

Shimadzu’s broad lineup of FTIR and Raman accessories significantly extends the analytical capabilities of spectrophotometers and microscopes. By matching sample form and measurement requirements with dedicated attachments and software tools, chemists can achieve high-throughput, high-sensitivity and highly reproducible analyses across research and industrial applications.
