This study examined a comprehensive approach to quantifying iron in over-the-counter supplements through two laboratory experiments designed for undergraduate students in analytical chemistry and ...

The Vision Visible and UV-Visible Spectrophotometers. Accurate flexible visible spectrophotometers in a compact package – packing premium performance into a portable design for user friendly labs. The ...

UV–vis spectroscopic analysis of lignin electrolytes, before/after depolymerization and cycling, was performed by a Genesys 10S UV–vis spectrophotometer (Thermo-Scientific). Samples were diluted to 10 ...

To determine the fluorescence quantum yield, samples were first evaluated using a UV-Vis spectrophotometer (Genesys 10S, Thermo Fisher Scientific, Madison, USA) within the 190-500 nm range, using a ...

Ultraviolet-visible (UV-Vis) spectroscopy is a widely used technique in many areas of science ranging from bacterial culturing, drug identification and nucleic acid purity checks and quantitation, to ...

For the peroxidase enzyme, the method described by Pascual et al. (1983) we used guaiacol and hydrogen peroxide as substrates.The assay conditions were 1.0 mL 0.01 M Tris (HCl), pH 7.0, 0.75 mL 100 mM ...

The silver nanoparticles were characterized by UV-Vis spectrophotometer (UV-Vis) and Scanning Electron Microscope (SEM). The biosynthesized silver nanoparticles were monitored and measured using ...

The analysis of C, H, and N components of the compounds and their metal complexes was performed on CHNS/O ANALYSER (Perkin Elmer PE2400 Series II). Electronic absorption spectra were recorded on ...

The concentration of chlorophylls was estimated as described elsewhere (Ciardi et al., 2022) using a Genesys 10S UV–Vis spectrophotometer (Thermo Fisher Scientific, Spain). Furthermore, the total ...
