Experimental setup and proof of concept. (A) The electrolytic spray setup is illustrated. (B) Electrolytic spray of 99.99% pure Pt-wire (rest are Au and Ag impurities) in positive ion mode showing Pt+ as major ion. During the initial spraying time more reactive impurities like Ag and Au were detected due to electrochemical etching.
