In situ loss measurement of direct UV written waveguides using integrated Bragg gratings

, 2010
The propagation loss of a direct UV-written silica-on-silicon waveguide is measured using an elegant nondestructive method. The technique uses integrated Bragg grating structures, which are observed from opposing launch directions to obtain information ...

BIOEQUIVALENCE OF NORFLOXACIN BY HPLC-UV METHOD [PDF]

Journal of the Chilean Chemical Society, 2010
ABSTRACT A simple, rapid and convenient high performance liquid chromatographic method has been developed for the determination and bioequivalence of norfloxacin in tablets formulations by using ciprofloxacin as an internal standard. The chromatographic separation was achieved on a C18 column having an isocratic mixture of methanol, disodium hydrogen ...

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same

Comments on a Method to Measure Sucralose Using UV Photodegradation Followed by UV Spectrophotometry

Journal of AOAC INTERNATIONAL, 2017
Abstract A simple and quick method to measure sucralose in aqueous solution at concentrations in the order of 0.1–1.2 g·L−1 proposed by Idris et al. uses UV irradiation prior to UV spectrophotometry. The photolysis of sucralose forms a photoactive compound characterized by maximum absorbance at approximately 270 nm.
