Glow
discharges sputter atomized particle conducting solid samples to form an
atomic and ionic population representative of the bulk cathode material.
These sources have found application in a variety of analytical atomic
spectroscopic methods over the past decade, including atomic absorption,
atomic emission, atomic fluorescence, and mass spectrometry.

First, a
high potential is applied between electrodes (cathode, anode). When the potential
between electrodes is exceeded, the gas particles are polarized and
than ion and electron are separated from it (Breakdown of particle).

T he electron from gas particles
is accelerated to the cathode surface and sputters the particle of cathode
surface (Sputtering effect). The ion from gas particles is accelerated
to a anode but it collide with other electrons during flying to the anode.

t's just
one-particle-environment assumption in
the Cell. So The real situation of the Discharge is not same as that. you must remind that.
