Comparison of the Internal Energy Deposition of Direct Analysis in Real Time and Electrospray Ionization Time-of-Flight Mass Spectrometry

The internal energy (E int) distributions of a series of p-substituted benzylpyridinium ions generated by both direct analysis in real time (DART) and electrospray ionization (ESI) were compared using the “survival yield” method. DART mean E int values at gas flow rates of 2, 4, and 6 L min −1, and...
