FTIR Spectroscopy

FTIR spectroscopy is an analytical technique employing Fourier transform infrared measurement enabling rapid chemical compound identification and material characterisation through infrared light absorption or reflection analysis. The spectroscopic approach provides compound-specific signatures enabling automated identification.

FTIR spectroscopy methodology employs infrared spectrometers measuring light transmission, reflection, or emission across infrared wavelengths (typically 400–4000 cm⁻¹ or 2.5–25 micrometres). Fourier transform algorithms convert time-domain interferometric measurements into frequency-domain spectral data revealing molecular vibration patterns characteristic of specific compounds. Spectral features indicate functional group presence enabling structural determination.

Operational principles include Beer-Lambert law governing light absorption enabling quantitative analysis, reference spectra enabling compound identification through pattern matching, and baseline correction compensating for instrument drift. Real-time measurement enables immediate results without extended processing.

Deployment applications include pharmaceutical analysis verifying active ingredient identity and purity, environmental monitoring characterising pollutant composition, forensic analysis identifying explosive or drug residues, materials science characterising polymer or coating composition, and food quality control detecting adulteration or contamination. Rapid analysis enables quality verification within minutes.

Sample preparation methods span direct measurement of solids or liquids, gas analysis measuring vapour compounds, and microscopic examination of small specimens. Diverse sample preparation options address varied analytical requirements.

Advantages include rapid analysis without destructive testing, high specificity enabling compound discrimination, and non-contact measurement preventing sample contamination.

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