（イ）産業上の利用分野
本発明は、原子吸光分析に使用する原子化装置に関する

消耗が激しいという問題があった。(B) Conventional technology Conventionally, flameless atomization devices run a large current through a tube made of graphite to generate heat to a temperature of nearly 3000'O, and use this thermal energy to atomize the sample. Due to the non-uniform resistivity distribution of the tube, there are problems such as uneven heating, resulting in a decrease in sensitivity, and contact between the hot tube and the sample, resulting in severe wear and tear on the tube.

High frequency coil 4 with several turns connected to high frequency power supply 3 of z
The outer periphery is surrounded by a graphite tube 5. In the figure, reference numeral 6 indicates a sample container support, and 7 indicates a bushing that connects the high-frequency coil 4 and the high-frequency power source 3.

り高周波電磁界の作用を受けず、昇温することはない。In this embodiment, when a sample is placed in the sample container 2, connected to an atomic absorption spectrometer, and high-frequency power is supplied to the high-frequency coil 4, the sample in the container 2 will be affected by the high-frequency electromagnetic field regardless of its diffusion state. It is uniformly exposed to radio frequency heat and atomized, which is then detected with high sensitivity by an analyzer. On the other hand, the sample container 2 itself is not affected by the high-frequency electromagnetic field due to the skin effect, and the temperature does not rise.

る。(f) Effects 2. As explained above, according to the present invention, the sample in the sample container is directly heated by high-frequency power, so the specific resistance distribution of the sample container and the diffusion state of the sample are controlled. It is possible to atomize the sample under constant conditions regardless of the situation, and not only can the sample be analyzed stably with high sensitivity, but only the sample can be heated, preventing corrosion of the sample container and reducing the consumption of the container. It can be suppressed.
