Flow-injection spectrophotometric determination of paracetamol in tablets and oral solutions.
TL;DR: A flow injection method is proposed for the determination of paracetamol in pharmaceutical dosage forms and the results were compared with those obtained by the official HPLC method, with relative standard deviations below 1%.

Flow-injection spectrophotometric determination of salbutamol with 4-aminoantipyrine
Isabel Dol,Moisés Knochen +1 more
TL;DR: A flow-injection method that involves the condensation of salbutamol with 4-aminoantipyrine in the presence of hexacyanoferrate (III) in alkaline medium producing a coloured quinoneimide that was detected absorptiometrically at 500nm is proposed.

Flow-injection determination of phenylephrine hydrochloride in pharmaceutical dosage forms with on-line solid-phase extraction and spectrophotometric detection
Moisés Knochen,Javier Giglio +1 more
TL;DR: A flow injection method is proposed for the determination of phenylephrine hydrochloride in pharmaceutical dosage forms that exhibits appropriate linearity and a significant reduction of interferences was found when applied to commercial samples containing several active ingredients and excipients.
