The ions pass through a foil, which strips off each ion's two electrons, converting it to a proton.

The ions thus start out being attracted to the terminal, pass through and become positive, and are repelled until they exit the tube at ground.

The electrolyte is a substance specifically designed so ions can pass through it, but the electrons cannot.

The ions pass through the accelerating electrode and strike the target.

The detector records either the charge induced or the current produced when an ion passes by or hits a surface.

They form hexagonal pores or channels through which ions, sugars, and other small molecules can pass.

The use of a porous barrier allows ions to pass through but keeps the solutions from mixing.

The channel pore is typically so small that ions must pass through it in single-file order.

Because the membrane of the cells is semi-permeable, certain ions cannot usually pass into the cell.

Only ions with specific mobility will pass through the device.
