Complete workflow for determining the content of nevirapine and related impurities
25 Mar 2021In both research and development and quality control pharmaceutical laboratories, determining the content of an active pharmaceutical ingredient (API) and its related impurities are typical analyses. While it is common to apply different methods for assay and impurity determination for one API, for instance in many pharmacopoeia monographs, in practice it is preferred to combine both analyses into one single run. Using a software assisted method development approach is hereby a very practical tool to speed up the method development process to save time and resources.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.

Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. Trace Level ImpuritiesTrace level impurities refer to low concentrations of unwanted substances found in chemicals, pharmaceuticals, and other products. Detecting and removing these impurities is crucial for product safety and regulatory compliance.
