2 simple chemometric spectrophotometric techniques; isosbestic factor and double wavelength approaches were developed, verified and applied to the resolution of metoprolol succinate in existence of amlodipine besylate in their binary blends and in mixed tablet formula while amlodipine besylate was identified by straight spectrophotometry at λ = 365 nm within linearity variety of 2-25 μg/ mL. 2 suggested chemometric spectrophotometric approaches were established for the spooky resolution of metoprolol succinate in existence of amlodipine besylate without initial separation with a linearity series of 2-30 μg/ mL metoprolol succinate. The mean portion recuperation ± SD was 100. 110 ± 0. 249 for metoprolol succinate. The 2nd method was twin wavelength method, metoprolol might be identified alone utilizing the absorbance distinction in between 226 nm and 248. 7 nm where the absorbance distinction was absolutely no for amlodipine at these 2 wavelengths. The mean portion healing ± SD was 99. 734 ± 0. 438 for metoprolol succinate utilizing double wavelength approach.
