FTIR Analysis

FTIR (Fourier transform infrared) analysis is a spectroscopic technique measuring infrared light absorption or emission enabling identification of chemical compounds and material composition. The analysis approach provides rapid compound identification without requiring destructive testing or chromatographic separation.

FTIR analysis methodology employs infrared spectrometers measuring light transmission or reflection across infrared wavelengths (typically 400–4000 cm⁻¹). Fourier transform algorithms convert time-domain measurements into frequency-domain spectral data revealing molecular vibration patterns characteristic of specific compounds. Spectral libraries containing reference spectra enable automated compound identification through pattern matching.

Operational specifications include spectral resolution typically 1–4 cm⁻¹ enabling fine spectral features, sensitivity detecting picogram quantities enabling trace analysis, and analysis time <30 seconds enabling rapid screening. Real-time data display enables immediate results.

Deployment applications include pharmaceutical analysis identifying active ingredient composition and purity, environmental monitoring characterising pollutant composition, forensic analysis identifying explosive or drug residues, and materials science characterising polymer or coating composition. Rapid analysis enables quality control without laboratory delays.

Sample preparation methods span direct measurement of solid or liquid samples, gas analysis measuring vapour-phase compounds, and microscopic analysis examining small specimen quantities. Diverse sample preparation options address varied analysis requirements.

Integration with computers enables automated measurement and data analysis. Spectral comparison against reference libraries enables rapid compound identification. Statistical analysis quantifies uncertainty in identification.

In Pakistan, FTIR analysis supports quality control and forensic investigations.
