Fuel cell analysis using FTIR spectroscopy. FTIR spectroscopy combined with electrochemical measurements can provide real-time molecular characterisation and quantitative reaction kinetics analysis. Fuel cells using alternative fuels like ethylene glycol are a promising clean energy solution. Understanding interm...
The analysis of microplastic samples by Fourier transform infrared (FTIR) spectroscopy is a versatile, bias-free tool to succeed at this task. In this study, we provide an adaptable reference database, which can be applied to single-particle identification as well as methods like chemical imaging...
The data were collected using OMNIC™ spectroscopy software, and the chemometrics were performed using TQ Analyst™. The procedures for the analysis followed, in general, the guidelines developed by the ASTM Committee on biodiesel analysis using Partial Least Squares (PLS) method for quantitative ...
(ATR-FTIR) spectroscopy for predicting PMI based on vitreous humor (VH). VH samples were collected from 72 rabbits in the range of 0–48 h postmortem at a 6-h interval. Their FTIR spectra were normalized by the extended multiplicative signal correction (RMSC) and divided into calibration and...

2.8. FTIR Spectroscopy The FTIR spectra of the dried extracts were acquired by attenuated total reflectance (ATR) through a diamond cell on a Nicolet 6700. All spectra were recorded at a spectral resolution of 4 cm−1, and 16 scans were performed per sample in the 4000–650 cm−1 range...
Additionally, probability density functions (PDF) for each explosive are presented as the margin plots (b). 4. Conclusions Numerous studies have shown that FTIR spectroscopy is a powerful method for classifying various samples based on differences in their chemical content. It is a straightforward ...
