Descripción general
SUPELCOSIL LC-ABZ phase has a unique deactivation technology which provides excellent reversed phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar. Silanol suppressing additives and techniques such as competing amines, high ionic strength, and pH extremes are typically not required to obtain good peak shape on the LC-ABZ phase.
Características y beneficios
• For acids, bases, zwitterions
• Increased polar retention relative to standard reversed-phases
• Unique selectivity
• Silanol deactivation
• Peak shape, efficiency, and retention are comparable to C8 phases for non-polar analytes
• Increased polar retention relative to standard reversed-phases
• Unique selectivity
• Silanol deactivation
• Peak shape, efficiency, and retention are comparable to C8 phases for non-polar analytes

To study the pharmacokinetics of dextromoramide in long-term opiate addicts on methadone maintenance therapy (MMT) a reverse-phase HPLC technique was developed to monitor dextromoramide and methadone concentrations in plasma simultaneously. After liquid-liquid extraction from plasma, dextromoramide and methadone were determined

The solvation parameter model is used to identify suitable chromatographic models for estimating the octanol-water partition coefficient for neutral compounds of varied structure by reversed-phase liquid chromatography. The stationary phase Supelcosil LC-ABZ with methanol-water mobile phases affords a series of

A high-performance liquid chromatographic method with electrochemical detection was developed for the simultaneous determination of five 1,4-dihydropyridines: amlodipine, nitrendipine, felodipine, lacidipine and lercanidipine. These drugs are widely used in the treatment of hypertension, angina pectoris and the therapy of cerebrovascular
