Q absorbance method
WebThe method involved Q-absorption ratio analysis using two wavelengths obtained by the overlay spectrum of the Metformin and Canagliflozin, with one being the maximum absorbance wavelength of Canagliflozin (220 nm, 2) and the other being the iso-absorptive point of both drugs (250 nm, 1). The method was validated as per WebQ-Absorbance ratio spectrophotometric method for the simultaneous estimation of Cefpodoxime Proxetil and Levofloxacin Hemihydrate in their combined dosage form. …
