The following poster was presented at the Extractables & Leachables session of the annual conference of American Society for Mass Spectrometry (ASMS) in Minneapolis.

Routine E&L testing of medical devices requires extraction using three solvent systems with differing polarity: nonpolar (like hexane or DCM), mid-polar (like IPA), and polar (like water), which is usually followed by the mass spectrometry analysis. While GC-MS and LC-APCI-MS are conventionally used to analyze hexane extracts, there is a growing (and specific) demand for the analysis of hexane extracts by LC-ESI-MS. Hexane is considered one of the non-compatible solvents for the ESI due to its highly nonpolar nature. Therefore, we studied evaporation and reconstitution of selected E&L quality control chemical standards from hexane & IPA to different ESI-compatible solvents. Results show the possibility of achieving the desired analysis without losing the method’s analytical sensitivity and selectivity.
