Graphite furnace atomic absorption spectrophotometer

Abstract

The utility model discloses a graphite furnace atomic absorption spectrophotometer, which comprises a shell and a flame atomizer, the shell is provided with a movable door capable of being opened and closed, the movable door is detachably connected with a heat dissipation mechanism, the heat dissipation mechanism comprises a heat dissipation frame, a protective cover, an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are oppositely installed on the front face and the back face of the protective cover, the heat dissipation frame is arranged in the shell, and the protective cover is connected and fixed to the movable door in an inserted mode. According to the flame graphite furnace, through the arranged heat dissipation mechanism, heat dissipation can be conveniently carried out on a combustion area in the flame graphite furnace, a combustor in the flame atomizer is prevented from damaging a shell of the photometer, through the protective cover, the air inlet pipe and the air outlet pipe, dissipation of the temperature above the combustor can be conveniently accelerated, and meanwhile through the detachable heat dissipation mechanism, the heat dissipation efficiency is improved. And the atomic absorption spectrophotometer can be conveniently assembled with the spectrophotometer and the heat dissipation mechanism can be conveniently maintained, so that the atomic absorption spectrophotometer has heat dissipation and protection effects.
