Fourier transform infrared (FTIR) authentication and batch‐to‐batch consistency for different types of paints using benchtop and handheld FTIR spectrophotometers for oil and gas industry

Standardization of Fourier transform infrared (FTIR) fingerprint region for paints and assessment on the reproducibility using different spectrophotometers were investigated. While selective fingerprint regions may be confusing for technicians/analysts who are non‐chemists, we attempt to generalize these regions (e.g., 1300–1000 cm −1 for Epoxy part A and 1400–1000 cm −1 for Epoxy part B) by choosing a universal region (2000–900 cm −1 ) that...
