Caractérisation des solvants utilisés dans les batteries : identification des impuretés présentes dans le carbonate de diméthyle

This analysis demonstrates how the high sensitivity and high-resolution mass spectrometry of the Pegasus BTX and Pegasus HRT detect below-ppb-level contaminants in Dimethyl Carbonate (DMC). By accurately identifying unexpected organic species like nitriles and alcohols, manufacturers can optimize solvent production and prevent critical downstream battery failures such as gas buildup and efficiency loss.
