  • the sealing part 140 since the sealing part 140 is provided in a structure completely surrounding the spout 131a, the sealing part 140 may be provided as an O-ring. As such, the sealing part 140 is provided and the sealing part 140 is interviewed with the object 50 so that the sealing part 140 is made of a material that hardly damages the object 150. do.
  • the material of the sealing part 140 may include rubber, Teflon, and the like.
  • sealing part 140 in a black series as a part to more effectively block the outside through the blocking part 130. That is, when the sealing unit 140 is provided in a black series, the end of the second providing unit 113 and the end of the detector 115 can be blocked more efficiently from the outside.
  • the analysis device 100 uses the blocking unit 130 to analyze the concentration of the contaminant or the like on the object 150 in real time and the detector and the end of the second providing unit 113. Since the end portion of 115 can be blocked from the outside, it is possible not only to analyze ppb to ppt in real time, but also to prevent the solution causing chemiluminescence from splashing out of the analysis region and to measure light intensity. It is possible to improve the light collection efficiency. Therefore, not only the analysis of the concentration of the pollutant and the like remaining in the object 50 using the analysis device 400 may be performed in real time, but also the improvement of the reliability of the data according to the analysis may be expected.
  • the analysis apparatus forms a liquid sample in the object itself, and analyzes the concentration of the pollutant and the like using the same, or analyzes the concentration of the pollutant and the like for the object by performing the transfer in real time using a transfer unit or the like. It is possible to do
  • the member for providing a solution for generating chemiluminescence phenomenon and the member for measuring the intensity of light can be blocked from the outside.
  • the analysis apparatus of the present invention not only can perform ppb to ppt analysis in real time, but also prevents the solution generating the chemiluminescence phenomenon from splashing out of the analysis region, and at the same time, the light collection efficiency according to the measurement of the light intensity. Can improve and shorten analysis time. Therefore, the analysis apparatus of the present invention can be more actively used in the field requiring the action according to the analysis in real time.

Abstract

La présente invention concerne un dispositif d'analyse de solution échantillon, lequel dispositif comprend un premier réservoir qui fournit une première solution qui constitue une solution de contrôle, telle qu'un échantillon liquide et un second réservoir qui fournit une seconde solution produisant une réaction chimioluminescente avec la première solution; et un détecteur qui calcule la concentration de l'échantillon liquide par mesure de l'intensité de la lumière émise par la seconde solution.
