A recent study used Fourier transform mid-infrared (FT-IR) spectroscopy and machine learning (ML) algorithms to understand the mineral content in camel’s milk.

Researchers have developed a rapid, reagent-free method to estimate the saponification value (SV) of edible oils using handheld Raman spectroscopy. This innovative approach simplifies oil quality testing, cutting time and costs while enhancing accuracy and portability.

We critically review the qualification and validation approaches in the World Health Organization Technical Report Series (WHO TRS) 1019 Annex 3 and its applicability to spectrometer systems.

Vibrational spectra of six new hexafluorosilicate salts containing different amino acids (glycine (Gly), sarcosine (Sar), dimethylglycine (DMG), betaine (Bet), β-alanine (β-Ala) and l-proline (l-Pro)) are typically recorded and discussed on the basis of their structures. The presence of cations, dimeric cations with short hydrogen bonds, and hexafluorosilicate anions is reflected in the spectra.
