Creating Greener HPLC Methods as Measured by the AMGS Metric: A Case Study of Improving USP Monograph Methods
HPLC is a versatile and widely used method for analyzing various compounds, particularly in the pharmaceutical industry. It's preferred by generic pharmaceutical companies and quality control groups due to its accessibility compared to newer technologies like Ultra-Performance Liquid Chromatography (UPLC™). In recent years, there has been a growing emphasis on making analytical chemistry techniques, such as HPLC, more sustainable. These "green" initiatives aim to reduce the use of toxic reagents, minimize waste, and lower energy consumption, all while maintaining high scientific standards. This app note highlights Development of a new, greener HPLC method for rivaroxaban and impurities, aligned with the USP monograph and using the Analytical Method Greenness Score (AMGS).
Is “right first time, every time” a pipedream for metabolite identification by LC-MS?
March 18th 2025The dream state If we lived in an ideal world, it would be possible to unambiguously identify metabolites using a single analytical experiment. This analytical technique would need to be efficient and easily generate the information needed from a routine assay that is also robust, enabling confident decision-making during drug discovery. At SCIEX, we believe that metabolite identification using the ZenoTOF 7600 system gets close to this dream state.
