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 practices such as using competing amines, operating at high ionic strength, and adjusting mobile phases to pH extremes are typically not required to obtain good peak shape on the LC-ABZ phase.
Features and Benefits
• 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

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
