Electrospray is a phenomenon where an electrically charged liquid is sprayed after applying a high voltage to a narrow tube filled with liquid. By using the phenomenon, the development of surface treatment and functional materials including spectrometry (LC-MS) like electrospray ionization (ESI), along with electrostatic atomization (EAS), electrostatic dispensing (EPD), etc. is accelerated.

Also, utilizing such an innovative technology like Femto-reactor, the development of materials, compounds, and medicines are implemented.

Positively charged droplets flies toward the negative electrode.

Matsusada Precision provides specially designed high voltage power supplies for supplying roughly 2kV to 5kV voltage in electrospray ionization (analysis).
Concerning various material development related to Femto-reactor technology, our high-performance high voltage power supplies featuring low ripple as well as high stability perfectly fit the application.
