Spectrophotometric Method for Determination of Azelaic Acid: Development and Validation Approach | Chapter 17 | Advanced Concepts in Pharmaceutical Research Vol. 3

 This phase evaluates to develop accurate, plain, UV spectrophotometric method which is empty extraction techniques, and smaller time and highly delicate technique. This study illustrates a simple, accurate, exact and cost effective UV-visible spectrophotometric plan for the estimation of Azelaic acid in pure and drug formulations. The analytically useful working groups in Azelaic acid have not been adequately exploited for designing appropriate, visible spectrophotometric methods accordingly still offer a scope to expand more visible spectrophotometric methods accompanying better sensitivity, selectivity, accuracy and accuracy. The method is established the measurement of absorbance of Azelaic acid solution in Phosphate safeguard pH 6.8 at 204nm in the wavelength range of 200-400nm. When using sure media and concentration ranges of 10–50ยต g/ml, the process complies with Beer’s Lambert’s standard. Calculations were still performed for the slope, intercept, and equivalence coefficient. The presence of coarse excipients in tablets did not impair the process, according to the results of the percentage improvement investigation. In accordance with the approvals set forth by the Worldwide Conference on Harmonization (ICH), determinants such as extent of object, precision, accuracy, and feeling studies, which includes limit of discovery and limit of quantitation, were examined. The proposed form was found to be natural, accurate, precise and expeditious for the routine determination of Azelaic acid in pure and drug formulation.

Investigation of Optical Properties of Thin Films by Means of UV-visible Spectrophotometer: A Review| Chapter 5 | New Frontiers in Physical Science Research Vol. 5

 Thin films have existed synthesized using various deposition orders such as chemical usually deposition, vacuum dissolution, thermal dissolution, sputtering, hydrothermal, dip coating arrangement and pulsed laser dethroning. In this work, UV-visible spectrophotometer method was employed to study the optical features and band gap of the obtained thin films. UV-seeable spectrophotometer technique has many benefits such as rapidly study ability, cost effective, flexible and simple to use. This method measures the absorption or transmission of light that pass through the samples as a function of wavelength. The band gap was about 1.5 eV, doubled the solar range.
