In extractables studies, LC/UV/MS is commonly used to detect and annotate the non-volatile fraction of compounds. Industry guidance and regulatory requirements indicate an analytical evaluation threshold (AET), above which compounds need to be identified to allow for toxicological risk assessment, requiring estimated quantitation before their identity is known. UV and MS detector response is known to vary for analytes, requiring the use of an uncertainty factor to account for difference in response relative to a reference standard at the AET.
In this webinar, we will discuss the challenges associated with these analyses and present strategies that can be deployed to reduce uncertainty in LC/MS extractable studies, including the combination of the three detection techniques in one system to allow the concurrent measurement of UV absorption, CAD signal, and high resolution-accurate mass (HRAM) mass spectra from one injection.
