In thiswork, a porous carbon furnacewas employed as the vaporizer
for Cd instead of the graphite fiber felt used in the previous study [12].
However, the power and duration of electrothermal vaporization had
to be re-optimized under the newconditions of the gas circuit and composition
for SS-ETV-ICP-MS. Thus, approximately 2 mg of rice, spinach
and pork liver
