Electrospray

Electrospray is a technique that produces a fine, electrically charged spray by applying a high voltage to a liquid flowing through a narrow tube. This technique is driving advances in the development of surface treatments and functional materials. Key applications include electrospray ionization (ESI) for liquid chromatography-mass spectrometry (LC-MS), electrostatic atomization (EAS), and electrostatic dispensing (EPD).

Furthermore, it is integral to innovative technologies like the Femto-reactor, enabling the rapid development of new materials, compounds, and medicines.

Positively charged droplets fly toward the negative electrode.

For electrospray ionization (ESI) analysis, Matsusada Precision offers specially designed high-voltage power supplies that deliver approximately 2 kV to 5 kV. For material development involving Femto-reactor technology, our high-performance high-voltage power supplies are ideally suited. They deliver the low ripple and high stability required for these demanding applications, ensuring precise and repeatable results.
