【発明の詳細な説明】
この発明は真空形発光分光分析装置、特にその発光部（
室）の構成に関するものである。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a vacuum-type optical emission spectrometer, particularly its light-emitting section (
This is related to the structure of the room.
従来の真空形発光分光分析装置の発光室は第１図のごと
く構成されている。The light emitting chamber of a conventional vacuum type emission spectrometer is constructed as shown in FIG.
すなわち図において１は真空形発光分光分析装置の発光

料であり、６はこの試料４に対向し、試料との間で放電
をする対電極である。That is, in the figure, 1 is a light emitting chamber of a vacuum-type emission spectrometer, which is adjacent to a spectroscopic chamber 2 with a lens 3 interposed therebetween. 4 is a sample placed on the opening 5 of the light emitting chamber 1, and 6 is a counter electrode that faces the sample 4 and generates a discharge between it and the sample.
７は発光室１の分光室２側からのアルゴンガス導入路（
管）、８は対電極６の周囲からのアルゴンガス導入路（
管）、９は発光室１の分光室２と反対側に設けられたガ
ス（アルゴンガス）排出路（管）である。7 is an argon gas introduction path from the spectroscopy chamber 2 side of the light emission chamber 1 (
8 is an argon gas introduction path from around the counter electrode 6 (
9 is a gas (argon gas) exhaust path (tube) provided on the opposite side of the light emitting chamber 1 from the spectroscopic chamber 2.
以上の構成において発光室１内をアルゴンガス（一定圧
力、一定流量）で置換してのち、試料４と対電極６間で
放電が行なわれ、発生した光は、レンズ３を介して分光
室２内で分光され、その各スペクトルから含有物質の定
性あるいは定量が行なわれるのである。In the above configuration, after replacing the interior of the light emitting chamber 1 with argon gas (constant pressure, constant flow rate), a discharge is generated between the sample 4 and the counter electrode 6, and the generated light is transmitted through the lens 3 to the spectroscopic chamber 1. The substances contained therein are analyzed qualitatively or quantitatively from each spectrum.
しかし、従来のこの発光室の構成にあつては試料上の放
電面積を小さなある大きさに規制することが困難で放電
面積が大きく、よつて試料上の特定の箇所を精密に分析
することが不可能であつた。However, with the conventional configuration of this light-emitting chamber, it is difficult to control the discharge area on the sample to a certain small size, and the discharge area is large, making it difficult to precisely analyze a specific location on the sample. It was impossible.
なお、対電極も移動させて放電ギャップを変えて放電面
積を少しの範囲において変えたり、絶縁物で試料面を覆
つて放電面積を規制することはできるが、これらの方策
では光を有効に取り出すことができなかつた。すなわち

流す雰囲気ガスとしてのアルゴンガスは高純度のものを
使用しているが発光室内の汚れ、空気のたまり、等があ
るとアルゴンガスの純度が低下して放電が不安定になり
試料の蒸発量が低下する等の欠点も存在していた。Note that it is possible to change the discharge area within a small range by changing the discharge gap by moving the counter electrode, or to restrict the discharge area by covering the sample surface with an insulator, but these measures do not effectively extract light. I couldn't do it. In other words, ideally, it would be desirable for the light source (discharge luminescence) to be a point light source with a constant intensity when viewed from the spectroscopic chamber, from the viewpoint of analysis accuracy and effective use of light, but the conventional configuration is not satisfactory. It was not a kimono. In addition, high-purity argon gas is used as the atmospheric gas flowing into the light-emitting chamber, but if there is dirt, air accumulation, etc. in the light-emitting chamber, the purity of the argon gas will decrease and the discharge will become unstable. There were also disadvantages such as a decrease in the amount of evaporation.

析装置であり、以下図面に従つてこの発明を説明してゆ
く。In order to eliminate the above-mentioned drawbacks of the conventional technology, this invention reduces the discharge area, that is, makes it as close to a point light source as possible, and also sprays high-purity argon gas onto the sample surface as an argon jet. The purpose of this device is to generate a discharge within an argon column and to stabilize this discharge.The tip of the counter electrode has a nozzle section for spraying argon gas onto the sample surface as an argon jet. This is an optical emission spectrometer characterized in that discharge light is emitted while being blown, and another inert gas for substitution is introduced into the light emitting chamber.This invention will be described below with reference to the drawings.
第２図、および第３図はこの発明の放電室内の放電部を
図示したもので、第１図と同一符号は同一のものを示す
。2 and 3 illustrate the discharge section in the discharge chamber of the present invention, and the same reference numerals as in FIG. 1 indicate the same parts.
この第２図において、８はアルゴンガス導入路（管）で
、これは発光室内では細い形状の対電極６をその中心部
に有し、対電極の先端部では図のように対電極と導入管
とでノズル部１０を構成している。In this Figure 2, 8 is an argon gas introduction channel (tube), which has a thin counter electrode 6 in its center inside the luminescence chamber, and the tip of the counter electrode is connected to the counter electrode as shown in the figure. The nozzle part 10 is constituted by the pipe.
よつてアルゴンガスはノズルから噴出し、アルゴンガス

排出路（管）９によつて排出される。Therefore, argon gas is ejected from the nozzle and is blown onto the sample surface as an argon gas jet, forming a cylindrical argon gas column, and this argon column becomes a discharge path. On the other hand, in this configuration, a gas that is difficult to discharge, or a gas that does not absorb ultraviolet light, such as nitrogen gas N2, is introduced from the spectroscopic chamber side as shown by the arrow, and the argon gas in the light emission chamber and this nitrogen gas in the atmospheric gas are introduced. is discharged through a gas discharge path (pipe) 9.
また第３図においては対電極６を中空管として構成し、

This tube is intended to be used also as an argon gas introduction tube 8, and its tip also constitutes a nozzle section 10. On the other hand, in the configuration shown in FIG. 3, this counter electrode 6
A nitrogen gas introduction path (pipe) 11 is provided, and this introduction pipe 11 also forms another nozzle portion 12 at the tip of the counter electrode.

上非常に効果が発揮されるのである。In the configurations shown in FIGS. 2 and 3 above, after displacing the inside of the discharge chamber with nitrogen gas, when discharging while ejecting argon gas from the nozzle part 12, a discharge path is formed only in the argon gas column consisting of an argon jet. (Argon gas is easily excited and discharge can easily occur, but discharge is difficult to occur in nitrogen gas). In other words, if the argon jet itself is made thin and stable, the discharge path formed by the argon gas column made of dinit will become regulated and thin and stable, making it stable as a light source and extremely important in terms of analytical accuracy. The effect is demonstrated.

されずに安定な放電が可能となるのである。In FIG. 2, a stable discharge path is formed by an argon gas column consisting of an argon jet in a nitrogen gas atmosphere, and in FIG. The argon column formed by the nozzle 9 at the tip of the counter electrode is further sealed around its outer periphery by the nitrogen gas N2, which is even more stable than that shown in Fig. 2. A thin argon column, or discharge path, is formed. As described above, by generating discharge light while blowing an argon jet onto the sample surface, a very narrow discharge path can be obtained, making it possible to analyze a small area of the sample surface. Even if the discharge gap is changed from 5mm to 6mm, the size of the discharge (analysis) surface on the sample surface can be regulated to a diameter of about 1mm to 1.5m71L, which is 1/20 to 1/20 of the conventional size. We were able to reduce the size by 1/30. As a result, as mentioned above, it is possible to analyze small areas and also use small samples, which improves analysis accuracy and enables stable discharge regardless of the gas purity in the luminescence chamber. be.
