pseudoephedrine/dichloromethane

A highly sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method has been developed to determine rasagiline in human plasma. The analytical method utilized liquid-liquid extraction of plasma with n-hexane-dichloromethane-isopropanol (20:10:1, v/v/v). Separation of analyte and the

A rapid, sensitive and specific liquid chromatography-electrospray ionization mass spectrometric (LC-ESI-MS) method has been developed for the quantification of trimetazidine in human plasma. The analyte and the internal standard (pseudoephedrine) were extracted from plasma samples with

A rapid and sensitive method for the simultaneous determination of paracetamol and guaifenesin in human plasma was developed and validated, using high-performance liquid chromatographic separation with tandem mass spectrometric detection. After extracted from plasma samples by diethyl
