Sequential injection chromatogram for duplicate measurements of: (a) 25 μg/mL HTZ and 40 μg/mL PRP extracted from Inderide® tablets; (b) 40 μg/mL PRP extracted from Ciplar LA® tablets, (c) 25 μg/mL HTZ and 80 μg/mL PRP extracted from Inderide® tablets and (d) 25 μg/mL HTZ extracted from Lannett® tablets. Optimum conditions: C18 monolithic column (4.6 × 50 mm), a mobile phase composition of 75 mmol/L phosphate:acetonitrile (70:30, v/v) at pH 3.0, flow rate 30 μL/s, sample volume 40 μL, UV detection at 270 nm for HTZ and 290 nm for PRP.
