Nota de análise

The R- and S- forms of warfarin, a commonly prescribed anticoagulant, are cleared by the body via different pathways and have different pharmacokinetic and pharmacodynamic effects. An Astec CHIROBIOTIC V HPLC column provided rapid resolution of the enantiomers under conditions that are compatible with mass spectrometric (MS) detection. By using HybridSPE-Phospholipid for the sample prep, ion-suppressing phospholipids were removed for improved sensitivity and longer column lifetime. The highest grade LC-MS solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant reference material grade standards provided reliable quantification.
