することはない。 A water quality sample to be decomposed is placed in a sample decomposition container 1 together with a predetermined acid and oxidizing agent and is automatically heated according to the pattern shown in FIG. Since the generated decomposed gas is sucked and heated by the pump 9, the decomposed gas of organic matter or water vapor is collected in the collection gas reservoir 1.
b. The water passes through the suction port 1c, the suction pipe 2, the collecting pipe 3, the collection device consisting of the trap such as the condenser mentioned above, and is discharged from the pump 9 after being cleaned. Here, in this apparatus, the sample decomposition container 1 is a flask with a stopper, a collection gas reservoir 1b is formed in the stopper, and an outside air intake port 1c is provided. Since the generated water vapor can be taken in, smooth decomposition can be continued without condensing the generated water vapor in the suction pipe 2 and collecting pipe 3 and making it impossible to suction the gas. At this time, since the collecting gas reservoir 1b is formed within the stopper, the sucked outside air reaches the suction port 1d from the gas reservoir 1b, and does not contaminate the sample.

制御することが可能となつたのである。 Next, the heating device of this device will be described. In the heating device of the device of the present invention, the heating plate 11
A hole 11a is made in the part where the decomposition vessel 1 is placed, the bottom is sealed with a perforated plate 11b, and the heating plate 1 is
1 and the decomposition vessel 1 are directly radiated and at the same time heat transfer heating is performed from the heating plate 11. Therefore, by controlling the surface temperature of the heating plate 11, the temperature inside the decomposition vessel is indirectly controlled. It became possible.

ヒータを制御している方式に比し、装置が大幅に
簡易となる。 In other words, if a heat transfer heating method is used in which the sample container is simply placed on a heating plate and the temperature of the heating plate is controlled, a time lag occurs between the temperature inside the container and the temperature of the heating plate, making it difficult to quickly control the temperature inside the container. Not only is this impossible, but if the heater is controlled on and off, the temperature may greatly hunt around the set temperature, resulting in bumping or dryness due to overheating. On the other hand, in the device of the present invention that uses radiation heating, the temperature inside the container follows the temperature of the heating plate well, and no temperature abnormality occurs inside the container. Therefore, the temperature of multiple samples being decomposed can be controlled simultaneously by controlling the temperature of the heating plate, compared to the conventional method of detecting the temperature of each sample and controlling each heater. The device becomes significantly simpler.

It may also be made to fit into a. Further, the shape of the hole is not limited to a circular shape, but can take any suitable shape as required. Furthermore, although the reflector plate 13 is very useful for effectively performing radiant heating, it is not necessarily essential.
Although a quartz-coated electric heater is shown as a heater for heating, an appropriate radiant heater such as an infrared heater can be used. In addition, in the above explanation, we have talked about wet decomposition that does not require additional supply of acid or oxidizing agent, but when additionally supplying acid or oxidizing agent, an acid and oxidizing agent supply device must be installed.
