Agilent Cary 630 FTIR Spectrometer

Significance of the topic

FTIR spectroscopy is essential for rapid, non-destructive molecular analysis in quality control and research across chemicals, polymers, pharmaceuticals and academic settings.
Its compact, reliable and versatile platforms bring laboratory-grade performance to benchtop and field environments, streamlining routine analysis and ensuring compliance.

Aim and overview of the study

This application note examines the Agilent Cary 630 FTIR spectrometer—a highly compact, robust instrument designed for quantitative and qualitative analysis of solids, liquids and gases.
It highlights the system’s innovative sampling accessories, intuitive MicroLab software, and proven performance in diverse real-world applications.

Methodology and instrumentation

• Fourier Transform Infrared (FTIR) spectroscopic measurement with integrated interferometer and solid-state laser source.
• Interchangeable snap-and-go accessories: transmission, DialPath, TumblIR, diamond and germanium ATR, ZnSe multibounce ATR, specular and diffuse reflectance.
• Automated accessory recognition and software guidance via Agilent MicroLab FTIR.
• Optional compliance features (21 CFR Part 11, GLP/GMP) and minimal external utilities (power only).

Main results and discussion

• Optical performance: 25 mm aperture and short path interferometer delivering high sensitivity comparable to larger lab instruments.
• Liquid analysis: DialPath and TumblIR enable fast transmission measurements at selectable pathlengths (30–1000 µm) without spacers or syringes.
• Application examples: clear toluene spectra via ATR and DialPath cells; quantification of polyethylene-vinyl acetate copolymers; diffuse reflectance calibration of acetaminophen in starch.
• Software features: real-time spectral preview, color-coded specification alerts, one-click method loading, and seamless data export to advanced analysis packages.

Benefits and practical applications of the method

• Space efficiency: footprint of 20 × 20 cm, weight under 4 kg, ideal for bench, glove box or field use.
• User-friendly: software guides sample introduction, accessory selection and diagnostics in regional languages.
• Versatility: supports solids, liquids, gels, powders and gases for bulk chemicals, polymer testing, pharmaceutical QC and academic labs.
• Reliability: rugged optomechanical design tolerates vibration, humidity and tropical conditions with minimal maintenance.

Instrumentation used

• Agilent Cary 630 FTIR spectrometer with solid-state laser and Flexture interferometer drive.
