      A non-equilibrium approach voltamperometric temperature   measurement for tungsten filament atomizers was developed to   facilitate the transfer of thermal conditions between instruments   that possess different power supply regulation modes and   filaments. Large differences in the equilibrium and instantaneous   temperatures were found during the pyrolysis and atomization   steps of cadmium AAS analysis. By using the instantaneous   temperature, the pyrolysis and atomization behaviors of cadmium   were shown to be equivalent regardless of the power supply   regulation mode. The pyrolysis conditions optimized for a 15 V   filament were readily and accurately transferred to a 12 V   filament by applying the non-equilibrium voltamperometric   temperature model.
