本発明は熱伝導形ガス分析器と水素炎イオン形ガス分析
器とを備えたガスクロマトグラフによる定量分析装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a quantitative analysis apparatus using a gas chromatograph, which is equipped with a thermal conduction type gas analyzer and a hydrogen flame ion type gas analyzer.

ャリヤガスとして流通させる。The gas is adsorbed by a filler such as silica gel, alumina, or activated charcoal filled in the gas tank, and helium, argon, hydrogen, or the like is passed through as a carrier gas.
このとき試料ガス成分中、吸着剤に対する吸着力の弱い

続的に測定することによりガス分析を行なうものである
。At this time, the sample gas components are separated in order from those with the weakest adsorption power to the adsorbent, so gas analysis is performed by continuously measuring the separated component gases.
相ガス成分を測定する手段としては熱伝導度形ガス分析
器、水素炎イオン化形ガス分析器等が知られている。As means for measuring phase gas components, thermal conductivity type gas analyzers, hydrogen flame ionization type gas analyzers, etc. are known.

質を利用して定量分析を行なうものである。The thermal conductivity type gas analyzer has a thermal conductivity of P depending on the aV class of the gas.When determining the difference in thermal conductivity between the carrier gas and each component gas in the sample gas, it is possible to detect the difference in the thermal conductivity between the carrier gas and each component gas. Quantitative analysis is performed using the physical property that the surface-to-surface ratio is approximately proportional to the amount of each component gas.

が広がってピーク同志が１々り合うことになり、このた
め分離効率が低下するという問題があった。In addition, the flame ionization type gas analyzer adds high-purity water gas to the sample gas, and then sends clean air as a combustion aid gas for combustion. When a constant positive and negative voltage is applied around the combustion flame, any organic components present in the sample gas are decomposed, and the carbon in the components becomes free carbon, forming carbon particles and emitting electrons. This generates ions, 'fr, and ion currents. Using the physical property that the amount of ions released at this time is approximately proportional to the amount of each component gas, quantitative analysis of the organic components in the sample gas is performed by measuring the ion current.By the way, thermal conduction Both the organic and inorganic components in the gas were measured on day 11', but the quantitative value Δ was poor (lower limit of 10 (l p pm off degree)), and the There is a drawback that the r degree varies considerably depending on the gas. Sensitivity can be increased by changing the amount of sample gas introduced by 5 degrees, but there is a limit to the capacity of the separation column, which ranges from 0.5 to Only about 10IIll can be introduced. Even if the amount introduced could be increased, in that case, the peaks of each component gas on the gas chromatograph would spread and the peaks would overlap, and this Therefore, there was a problem that the separation efficiency decreased.
一方、水素炎イオン化形ガス分析器はぎ酸以外のすべて

感じガいので無機成分の分析には使えない。On the other hand, the flame ionization type gas analyzer has extremely good sensitivity for all organic components other than formic acid (lower limit is about 1 ppm), but it is very sensitive to inorganic components. It cannot be used for analysis of inorganic components.

うグルがあった。Therefore, when attempting to quantitatively analyze a sample gas containing both inorganic and organic components, separate columns and recorders are installed for the thermally conductive deformed gas analyzer and the flame ionization gas analyzer. There was a guru who said that the structure was complicated and the repeatability was poor.
壕だ、有機成分についてはともかくとして、無機成分に

記録計とを具備して構成される。In order to achieve the above objective, the quantitative analysis device using a gas chromatograph of the present invention is filled with an adsorbent and sequentially separates the sample gas adsorbed by the adsorbent into components by flowing a carrier gas = 5- Separation column , a thermal conductivity type gas analyzer that sequentially measures sample gas components supplied from this separation column, and a thermal conductivity type gas analyzer connected to the outlet side of this gas analyzer to measure the internal pressure of the separation column and the thermal conductivity type gas analyzer. a flame ionization gas analyzer that sequentially measures sample gas components supplied through the resistance column; The system is equipped with a 2-2 type recorder that inputs signals and records the measurement results from each gas analyzer on a gas chromatograph, superimposing them on recording paper.
以下本発明の一実施例を、図面を参照して説明する。An embodiment of the present invention will be described below with reference to the drawings.

It is transferred to the column 3 and first adsorbed by silica gel 9 filled as an adsorbent in the separation column 3. Then, by the flow of the carrier gas, components of the sample gas are separated in descending order of their adsorption power to the silica gel 9, which is an adsorbent, and are supplied to the thermal conductivity type gas analyzer 5. Therefore, the thermal conductivity type gas analyzer 5 continuously measures the supplied component gas and sends the coefficient to the recording side 8.

The resistance column 6 is not intended to adsorb component gases, but merely serves as a resistance to gas flow, and is filled with simalite 10 as a resistance agent. As a result, the pressure at the sample inlet 4 is approximately 4 Ky/ct/l.

Recording is done by superimposing them on the recording boat 11 and using two pens, each color-coded. At this time, the thermal conductivity type gas analyzer 5 will be able to obtain quantitative analysis results for both inorganic and organic components, and the flame ionization type gas analyzer 7 will be able to obtain quantitative analysis results for only the organic components. .

で済むので操作性も向上する。As described above based on the examples, the gas chromatograph quantitative analysis device of the present invention is filled with an adsorbent, and the sample gas adsorbed on the adsorbent is sequentially separated into multiple components by the flow of a carrier gas. a thermal conductivity type gas analyzer that sequentially measures the sample gas components supplied through the separation column; A resistance column that increases the internal pressure of the gas analyzer, a water cumulative ionization type gas analyzer that measures the components of the sample gas supplied through the resistance column, and the thermal conductivity type gas analyzer. and a 2-!!-type recorder that inputs the code from the hydrogen flame ionization type gas analyzer and records the measured seeds from each gas analyzer overlappingly on the same recording paper using a gas chromatograph. The feature is that a thermal conductivity type gas analyzer and a hydrogen flame ionization type gas analyzer are connected via a resistance column.
Since a common separation column and recorder are used, the structure is simple and the sample gas only needs to be introduced once, which improves operability.

とによってこの分析器における定量感度が窩められる。In addition, since the pressure of the separation column is increased by providing a resistance column, a large amount of test gas can be adsorbed, and many components flow into the thermal conductivity type gas analyzer. Quantitative sensitivity is determined.

来以上に高められることに々る。In addition, the high pressure of the sample gas in the separation column prevents the components from being biased, thereby preventing the occurrence of errors due to component bias. Furthermore, since each component gas is compressed inside the thermal conductivity type gas analyzer, the peaks of each component in the gas chromatograph are
) No misalignment occurs, narrow, sharp peaks are obtained for each component, and more accurate quantitative analysis results can be obtained. Also, in a hydrogen flame ionization type gas analyzer, the quantitative sensitivity can be increased more than ever before due to the inflow of a large amount of components.
