plasma temperature dropping from the excessive energy consumption
by molecular bond rupture, ionization and the heat conduction of H2.
Thus, the effects of 2%, 4% and 10% H2 on the ICP torch were examined.
The plasma torch could not be ignited in the 10% H2 atmosphere,
while it was stable in the 2% and 4% H2 atmospheres. From the literature
[35], 3% H2 (v:v) could be employed as the carrier gas for ICP-AES, and
accordingly, 4% H2 (v:v) mixed
