Nota de análisis

This application shows the extraction and analysis of antiarrhythmic cardiac drugs in plasma samples using LC/MS/MS. HILIC chromatography on Ascentis Express along with a selective sample preparation using HybridSPE-Phospholipid provided sensitivity and resolution. The highest grade LC-MS solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
