The high resolution obtained with this method is achieved by using a Symmetry C18 TM reverse phase HPLC column. The comparison of our results with those previously described by different authors, shows that highest performances are obtained without using relatively drastic conditions such as 0.2 M ...

A simple RP-HPLC method for the determination of pravastatin in tablet dosage form. Numerous HPLC conditions were tested for the determination of pravastatin. The best result was achieved by using Phenomenex Luna 5渭m C18( 150x4.6mm) ID column, and a mobile phase consisting of acetonitrile: ...
The HPLC system consisted of a Lichrosorb RP-C18 analytical column (4.6 脳 200 mm, 5 碌m) with FLD operated at excitation 228 nm and emission 310 nm. Mobile phase {CHsub3/subOH/(NHsub4/sub)Hsub2/subPOsub4/sub (67 mM) (pH 3.0)/triethylamine (TEA), 50/50/0.02 (v/v/v %)}...
HPLCenalaprilThis paper reported the determination of enalapril maleate by HPLC.Chromatographic conditions:ALLTIMA C18 5μ 250mm×4.6mm;the mobil phase consisted of mobil-acetonitrile-water-1 H3PO4 solution(60:5:33.5:1.5);UV detection at 215nm;acetophenone as internal standard.TheRSD of the ...
A C18 reverse phase column and an elution isocratic-gradient system is used with a mixture of water, acetonitrile and acetic acid. We describe the optimization process by studying the influence of the structural characteristics of these compounds on the quantitative chromatographic parameters: k, w ...
A simple, reproducible method was developed for the determination of levocetirizine and pseudoephedrine in tablet formulation using reverse phase HPLC method. HPLC separation was carried over on a thermo hypersil – keystone c18 (250 x 4.6mm, 0.5μ) isocratic ...
