High Voltage Mesh Assembly

Hi Padraig,

The mesh assy. is part of the electrostatic potential in the spray chamber. 

1. The mobile phase and analyte are nebulized (broken
into small droplets).
2. The mobile phase solvent evaporates from the
droplets (desolvation).
3. The charge density in the droplets increases until
the Raleigh limit (10E8 V/cm3) is reached, then the
droplet undergoes coulomb explosions and breaks
into smaller droplets.
4. Under the influence of the electrostatic potentials (Mesh Assy. part of this)  in
the spray chamber, the analyte ion is desorbed from
the droplet.
