Electrospray

Electrospray is a technique used to produce a fine, electrically charged aerosol by applying high voltage to a liquid flowing through a capillary. This method accelerates 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 Precision Dispensing (EPD).

Furthermore, electrospray technology is integral to advanced research, such as Femto-reactor applications, enabling the rapid synthesis and development of new materials, compounds, and pharmaceuticals.

Positively charged droplets fly toward the negative electrode.

Stable high-voltage output is critical for maintaining a consistent Taylor cone and ensuring uniform droplet size in these processes. For ESI analysis, which typically requires 2 kV to 5 kV, and for demanding Femto-reactor applications, Matsusada Precision offers high-performance high-voltage power supplies. Our units are engineered to deliver the low ripple and high stability necessary for precise, repeatable results.
