The potential of Raman and FT-IR spectroscopic methods for the detection of chlorine in human nail samples.

Although chlorine (Cl2) has been used as a chemical warfare agent since World War I there is no known specific and reliable biomarker to indicate the presence of chlorine. We distinguished chlorinated human nails from unchlorinated ones using Raman spectroscopy and Fourier Transform Infrared (FT-IR) Spectroscopy. This research was carried out between October 2018 and July 2019 on two nail samples taken from 55 male and 104 female volunteers.

Comparison of Spectral and Molecular Analyses for Classification of Long Term Stored Wheat Samples.

This study aimed to determine whether NIR spectroscopy and protein band analysis can differentiate the grain samples of 15 wheat genotypes stored for different periods: Group Ⅰ (91 weeks), Group Ⅱ (143 weeks), Group Ⅲ (194 weeks), and Group Ⅳ (246 weeks). Samples were harvested from previously-conducted field trials, and stored at +4 ℃. A-PAGE and SDS-PAGE methods were utilized to separate gliadin and glutenin fractions, respectively.
