PURPOSE:To make it possible to allow a furnace wall and an internal specimen to simultaneously reach a temp. required in atomization, by performing atomic absorbance without blocking pervious light by providing an auxiliary specimen injection member contacted with an atomizing furnace in a circular arc state in the axial direction thereof. CONSTITUTION:An auxiliary specimen injection member 5 is provided in a graphite cylinder 1 so as to be brought into surface contact with the inner surface thereof and a specimen is injected from a specimen injection port 2 to perform drying, incineration and atomization. In this case, the furnace 1 is heated by Joule heat due to resistance heating but an auxiliary member 5 having a thickness degree not blocking absorbing light is also heated to an almost same degree and the specimen on the auxiliary member 5 simultaneously reaches an atomizing temp. to be atomized. As mentioned above, the furnace wall and the specimen simultaneously reach a prescribed temp. and the resonance linear wavelength light of the objective element is allowed to permeate to make it possible to quantitatively measure the absorbancy thereof and effect can be also enhanced in microanalysis. |
