FOURIER TRANSFORM INFRARED SPECTROSCOPY TECHNIQUE FOR DETECTION OF HONEY AUTHENTICATION [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2015
Physico-chemical properties of honey and honey samples adulterated with glucose or sucrose were determined. Total soluble solids (TSS), pH and electrical conductivity of honey and its adulterated samples ranged between (84.10-84.50%), (3.80-4.63) and (11.

Mid-infrared supercontinuum-based Fourier transform spectroscopy for plasma analysis

open access: yesScientific Reports, 2022
Broadband mid-infrared (MIR) spectroscopy is a well-established and valuable diagnostic technique for reactive plasmas. Plasmas are complex systems and consist of numerous (reactive) types of molecules; it is challenging to measure and control reaction ...

High-speed Fourier-transform infrared spectroscopy with phase-controlled delay line [PDF]

open access: yes, 2020
Fourier-transform infrared spectroscopy (FTIR) is the golden standard of mid-infrared (MIR) molecular spectroscopic analysis through optically-encoded vibrational signatures. Michelson-type FTIR and MIR dual-comb spectrometers allow us to simultaneously investigate multiple molecular species via the broadband and high-resolution spectroscopic ...

Comparison of Raman and Fourier Transform Infrared Spectroscopy for the Quantification of Microplastics in the Aquatic Environment.

open access: yesEnvironmental Science and Technology, 2018
Microplastics (MPs, 500 μm were visually sorted and manually analyzed by μ-Raman and attenuated total reflection (ATR)-FTIR spectroscopy. Microplastics ≤500 μm were concentrated on gold-coated filters and analyzed by automated single-particle exploration
