A brief Review on Q-absorption Ratio Method in UV-Spectrophotometry

Abstract

This present work carries a brief review on Q-Absorption ratio method in UV-spectrophotometry. Absorption ratio method is used for the ratio of the absorption at two selected wavelengths one of which is iso-absorptive point and other being the λmax of one of the two components. The aim of this article is to give brief idea about various method developed using Q-Absorption ratio methodon combined dosage forms. It shows selection of wavelength, linearity study and choosing solvent for give combine dosage form. This study also gives brief idea about practical and industrial application of Q-Absorption ratio method.
