Simultaneous Determination of Atenolol and Metformin Hydrochloride by Reverse Phase High Performance Liquid Chromatography

Simultaneous Determination of Salbutamol Sulphate and Bromhexine Hydrochloride in Tablets by Reverse Phase Liquid Chromatography

A simple reverse phase liquid chromatographic method has been developed and subsequently validated for simultaneous determination of salbutamol sulphate and bromhexine hydrochloride. The separation was carried out using a mobile phase consisting of acetonitrile, methanol and phosphate buffer, pH 4 in the ratio 60:20:20 v/v. The column used was SS Wakosil-II C-18 with a flow rate of 1 ml/min and...

Spectrophotometric Methods for the Determination of Linagliptin in Binary Mixture with Metformin Hydrochloride and Simultaneous Determination of Linagliptin and Metformin Hydrochloride using High Performance Liquid Chromatography

Simple, accurate and precise Zero order, first derivative spectrophotometric and chromatographic methods have been developed and validated for the determination of linagliptin (LNG) and metformin HCl (MET). The zero order and first derivative spectrophotometric methods were used for the determination of LNG in the range of 5-30 μg mL(-1) by measuring the absorbance at 299 nm and 311 respectivel...

Simultaneous Determination of Four Preservatives in Foodstuffs by High Performance Liquid Chromatography

Background and objectives:  High concentration of preservatives in food may result in gastrointestinal disturbances whereby some patients suffering from asthma, rhinitis, or urticaria. The aim of this study is the introduction and optimization a new method for simultaneous determination of four preservatives (SB, PS, MP, PP) in foodstuff by high performance liquid chromatography. Materi...

Determination and Validation of Eflornithine Hydrochloride by (Rp-Hplc) Reversed Phase High Performance Liquid Chromatography

A simple highly sensitive, rapid, precise, accurate and specific RP-HPLC method was developed for quantification of eflornithine hydrochloride (2-difluoromethyl-DL-ornithine; DFMO) in its commercial formulation. In this RP-HPLC method, the separation was performed using BDS Hypersil 5μ C18 (150 X 4.6 mm) column at room temperature by using methanol: 2% of Glacial acetic acid in water (80:20 v/v...
