For the simultaneous determination of a binary mixture of amlodipine (AM) and atenolol (AT) in tablets, two approaches were accessible. The first method is the second derivative of the ratio spectra (2 DD) that obtained via dividing the absorption spectra of binary mixtures by a standard spectrum of one of the components and then the second derivat...

Simple, rapid and sensitive spectrophotometric methods for the determination of trace amounts of iron (II) and iron (III) were developed based on complex formation between 5-(4-Ethylphenyl azo)2-Hydroxybenzaldehyde oxime reagent with iron (II) and iron (III) in acidic medium. The reagent 5-(4-Ethylphenyl azo)2-Hydroxybenzaldehyde oxime has been syn...

The present study describes employing second derivative spectrophotometry for the simultaneous determination of atenolol and amlodipine in pure form and in commercial formulations. The method is simple, accurate, precise, and economic. The zero-crossing point technique was used for analysis of the drugs in the combined formulation. The method was f...

FI system was used for the determination of histamine. A mini-column filled with amberlite resin (weak cation exchanger) was introduced to the flow system. A 200 μL of the sample was injected into the carrier stream through the injection valve. The merged streams were passed through a quartz flow cell in a spectrophotometer connected to recorder. U...
