Fig. 5From: A unique revolutionary eco-friendly spectrophotometric technique for solving the spectral overlap in the determination of carvedilol and ivabradine in their binary combination: stability studyRatio spectra of 10.0 µg/ml of IVA (black line), CAR (red line) and their binary mixture (black dotted line), separately in distilled water, using spectrum of CAR (15.0 µg/ml) as a devisor showing the two selected wavelengths (294.0 and 320.0 nm)Back to article page
