本発明はプロセス用分析装置に関するものである。特に
本発明はサンプル液の移送手段の改善されたプロセス用
分析装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a process analysis device. More particularly, the present invention relates to a process analyzer with improved sample liquid transfer means.
サンプル源からサンプル液を取入れ、そのうちから所定

液の移送が可能なので、装置の構成上極めて合理的な方

れがある。Automatically performs a series of operations in which sample liquid is taken in from the sample source, a predetermined amount of sample liquid is measured and fractionated, it is intermittently transferred to the analysis section, analyzed, and then discharged from the analysis section. Process analyzers are widely used in industrial analysis. With such an analyzer,
The system is connected to a source, and the entire liquid distribution system is brought into a state where the degree of depressurization increases toward the liquid discharge port, so that the liquid flows within the distribution system toward the liquid discharge port. This liquid transfer method is extremely rational in terms of the device configuration, as it is possible to transfer sample liquid, various reagents, and washing liquids using one vacuum source.However, in this method, the entire liquid distribution system is under reduced pressure. As a result, air may be sucked in from gaps around connections, plugs, lids, etc. in various parts of the distribution system, and there is a risk that sample liquids and reagents may change in quality.

及ぼす。In addition, the analysis of Temple fluid was carried out using a mercury drop electrode by Poe J.
- When silography is used, some mercury in the capillary is sucked out when the analysis section is reduced in pressure and the liquid is transferred. Next, when the analysis section returns to normal pressure, the tip of the mercury in the capillary retreats into the capillary, and the liquid present in the analysis section enters the capillary. This contaminates the inner wall surface of the capillary, changes the mercury droplet formed at the tip of the capillary, and adversely affects analysis accuracy.
吸引方式に伴う上述の如き問題は、サンプル液取入口に
ポンプ全設置し、液の流通系全体全加圧系とする押込み
方式とすることによシ解決できる。しかしこの方式では

業分析装置に用いられるプランジャーポンプは、その内
部を完全に洗浄および乾燥させることが困難である。The above-mentioned problems associated with the suction method can be solved by installing a pump at the sample liquid intake port and using a push-in method in which the entire liquid distribution system is pressurized. However, in this method, the sample liquid passes through the pump, but it is difficult to completely clean and dry the inside of the plunger pump used in common industrial analyzers.
従って、複数のテンプル源から順次サンプル液を取り入

ある。Therefore, when sample liquids are sequentially taken in from a plurality of temple sources and distributed within the system, as many pumps as there are sample sources are required to avoid contamination of the sample liquids with the pumps. In addition, even when handling only one type of sample liquid, if the composition of the '+j' sample liquid changes significantly over time, it is necessary to mix the liquid in the pump and use a sample liquid that accurately shows this change over time. It is difficult to send the information to the analysis department.
本発明は上述の如き吸引方式および押込方式のいずれの
欠点をも解決するブノプル液移送方式による分析装置を
提供するものである。The present invention provides an analyzer using the bunople liquid transfer method, which solves the drawbacks of both the suction method and the push-in method as described above.

である。That is, the present invention includes a sample liquid analysis section having a sample liquid intake port, a long nozzle liquid measuring section, and a liquid discharge port. In a process analyzer that is designed to be able to flow to the sample liquid analysis section via suction, the liquid is transferred from the sample liquid inlet to the temple liquid measurement section, and then from the sample liquid measurement section to the sample liquid analysis section. The gist of the device is that the liquid is transferred by extrusion using an extrusion medium supplied to a sample liquid measuring section.

Moreover, these depressurization sources and pressurization sources are connected to the sample liquid flow path from the sample liquid inlet to the sample liquid measurement unit and then to the sample liquid analysis unit, but they are not built into the sample liquid flow path. The sample liquid sent to the liquid analysis section does not pass through these.
