Attach the sample tube 7 containing the acidic reagent 9 and the acidic reagent 9 to the auxiliary combustion gas blowing tube 4 through the stopper 1o, insert it into the sample tube container 1 through the insertion port 1a, and place the sample tube 1 above the heater 6. The container is sealed with the stopper 5 in this manner.

薬９と効率良く中和反応を起して炭酸ガスを発止する。After completing these preparations, inject the aqueous solution to be the sample into the sample tube 7 from the sample injector receiver 1b via the injection lower a using a sample injection device S such as a syringe, and at the same time inject high-purity auxiliary combustion gas. When flowing, the inorganic carbon component contained in the aqueous solution undergoes an efficient neutralization reaction with the acidic reagent 9 bubbled with the high-purity auxiliary combustion gas to emit carbon dioxide gas.

た後、炭酸ガス検出器３により濃度が測定される。In this way, when all the inorganic carbon components have been gasified and removed, the sample tube 7 is heated by pressing down the auxiliary gas blowing tube 4 and lowering the sample tube 7 to the position where it faces the heater 6. The water in tube 7 is evaporated. When the moisture disappears, the organic carbon that was dissolved in the sample becomes oxidation catalyst particles8.8.8...
It burns under the action of ... and becomes carbon dioxide gas. This carbon dioxide gas is transferred from the sample tube 7 to the container by high-purity auxiliary combustion gas]
After water is removed by a cold trap 2, the concentration is measured by a carbon dioxide gas detector 3.

This is a stopper made of a rubber magnet that seals the auxiliary combustion gas, and a combustion auxiliary gas outlet 11a that communicates with a high purity auxiliary gas source is bored here. Reference numeral 12 denotes a stopper made of a rubber magnet that seals the upper part of the sample tube 7, and holds the upper end of the vibrator 3 extending below the reagent surface so as to be open to the atmosphere.

させて炭酸ガス検出器３に運ぶ。In this embodiment, the sample tube 7 is filled with the oxidation catalyst particles 8 and the acidic reagent 9 and loaded with the stopper 12, and then inserted into the container 1 with the sample tube 7 adsorbed on the stopper 11 on the container 1 side. Plug body 1
] into the insertion port 1af. In this state, after injecting the sample through the sample injection lower a, if high-purity auxiliary gas is injected through the auxiliary gas outlet 11a, the high-purity auxiliary gas will be 2
The acidic reagent 9 and the sample are bubbled by being sealed by the two plugs 11 and 12 and ejected from the tip of the vibrator 13,
The generated carbon dioxide gas is discharged from the sample injection lower a into the container 1 and transported to the carbon dioxide detector 3.

により加熱され、内部の試料を炭酸ガスに変換させる。In this way, when the inorganic carbon has been discharged, a permanent magnet or an electromagnet M is used to apply a magnetic force to the stoppers 1 and 12 from the outside of the sample tube container 1, and the magnetic force between the stoppers 11 and 12 is applied. When the adsorption is released, the sample tube 7 moves downward and the heater 6
is heated to convert the sample inside into carbon dioxide gas.
なお、上述の実施例においでは、試料管をヒータ側に移
動させるようにしているが、無機炭素を排出させた後、
試料管に対向する位百でまでヒータを移動させても同様
の作用を奏することは明らかである。In the above embodiment, the sample tube is moved to the heater side, but after the inorganic carbon is discharged,
It is clear that the same effect can be achieved even if the heater is moved up to a point opposite to the sample tube.
また、この実施例においては試料管の側方から試料を注
入するようにしているが、上部から注入してもよいこと
は云うまでもない。Further, in this embodiment, the sample is injected from the side of the sample tube, but it goes without saying that it may be injected from the top.

変換させ、ついで加熱により有機炭素成分を炭酸ガスに
変換することかできで、１回の試料注入により無機及び
有機炭素成分を短時間で検出することができる。As described above, according to the present invention, the sample V containing the oxidation catalyst and the acidic reagent is placed in the pipe connecting the combustion auxiliary gas source to the carbon dioxide gas detector relative to the heating source. Since it is movable, it is possible to convert inorganic carbon components into carbon dioxide gas without heating, and then convert organic carbon components into carbon dioxide gas by heating. Can be detected in a short time.
また、酸化触媒を酸化試薬中に分散させて収容しでいる
ため、従来使用されていた充填型燃焼管に比較して触媒
の交換が簡単となるばかりてなく、酸化触媒が液体中の
有機炭素成分に作用するため触媒の利用効率を向上でき
で、使用量を減すことができる。In addition, since the oxidation catalyst is dispersed and housed in the oxidation reagent, it is not only easier to replace the catalyst compared to the conventionally used packed combustion tube, but also the oxidation catalyst is dispersed in the organic carbon in the liquid. Since it acts on the components, it is possible to improve the utilization efficiency of the catalyst and reduce the amount used.
