Piezoelectric vibration to an in-source surface ionized structure to assist secondary droplet reduction

摘要

An ion source comprising a nebulizer (1) and a target (10) is disclosed. The nebulizer (1) is arranged and configured to emit a stream of analyte droplets that, in use, are impinged on the target (10) and ionize the analyte to produce a plurality of analyte ions. Be adapted. The target (10) is vibrated by a piezoelectric vibrator to reduce the resulting secondary droplet size. [Selection] Figure 1
