A new reflectometer-spectrophotometer has been designed and constructed using state-of-the-art technology to enhance optical properties of materials measurements over the ultraviolet, visible, and near-infrared (UV-Vis-NIR) wavelength range (200 nm to 2500 nm). The instrument, Spectral Tri-function Automated Reference Reflectometer (STARR), is capable of measuring specular and diffuse reflectan...

The determination of hydroxymethylfurfural (HMF) in bee honey is performed by the spectrophotometric methods Winkler's and White's. Winkler method reads absorbances visible region spectrum, White measures ultraviolet (UV) regions spectrum. This study aims to compare methodologies HMF honey. For study, it was used a UV-visible spectrophotometer, 10 mm optical path quartz cuvettes, ten samples di...

Atomic absorption and emission spectroscopy in the ultraviolet and visible A schematic diagram of a UV-Vis spectrophotometer is shown in Figure.11. Preface Inductively co...

Drug counterfeiting has exaggerated dramatically over the past decade causing a significant threat to human health. It must be processed in regard to medicines and the matter isn't restricted to a violation of belongings rights, however clearly involves every kind of poor quality pharmaceutical merchandise, including falsified and substandard medicine. The present paper discuss the review of th...
