===Ultrasonication-assisted spray ionization===

Ultrasonication-assisted spray ionization (UASI) is similar to the above techniques but uses an ultrasonic transducer to achieve atomization of the material and generate ions.<ref>{{cite journal|last=Chen|first=Tsung-Yi|title=Ultrasonication-assisted spray ionization mass spectrometry for the analysis of biomolecules in solution|journal=Journal of the American Society for Mass Spectrometry|author2=Lin, Jia-Yi |author3=Chen, Jen-Yi |author4=Chen, Yu-Chie |pages=1547–1553|doi=10.1016/j.jasms.2010.04.021 |pmid=20547459|volume=21|issue=9|year=2010|doi-access=free|bibcode=2010JASMS..21.1547C }}</ref><ref>{{Cite journal|last=Chen|first=Tsung-Yi|title=Ultrasonication-assisted spray ionization mass spectrometry for on-line monitoring of organic reactions|url=https://zenodo.org/record/999715|journal=Chemical Communications|volume=46|issue=44|pages=8347–9|access-date=4 November 2011|author2=Chao, Chin-Sheng |author3=Mong, Kwok-Kong Tony |author4=Chen, Yu-Chie |doi=10.1039/C0CC02629H|pmid=20957254|date=4 November 2010}}</ref>
