Definitions

  • the detector main body having the cell chamber may be formed with an inlet pipe constituting a part of the makeup gas supply path and an outlet pipe constituting a part of the exhaust path.
  • the outlet pipe may be formed with an inner diameter smaller than the inlet pipe, or a connecting pipe having an inner diameter smaller than the inlet pipe may be connected to the outlet pipe or inserted into the outlet pipe. Good.
  • a makeup gas supply path 12 for supplying makeup gas is communicated.
  • a part of the makeup gas supply path 12 is configured by an inlet pipe 121 formed so as to extend from the detector main body 1 in a radial direction (a direction orthogonal to the axis L).
  • a makeup gas supply source (not shown) is connected to the inlet pipe 121.
  • the makeup gas supply path 12 communicates with the cell chamber 11 and can supply makeup gas into the cell chamber 11 from the makeup gas supply path 12.

Abstract

L'invention concerne un détecteur à capture d'électrons pouvant effectuer une analyse précise, même d'un échantillon de gaz présentant une concentration élevée en substances électrophiles. Selon une configuration fournie, lorsqu'un gaz d'appoint est distribué par un trajet d'alimentation en gaz d'appoint (12) à l'intérieur d'une chambre de cellule (11), le gaz dans la chambre de cellule (11) est sous pression. Par conséquent, le taux de contact entre le gaz d'appoint et le rayonnement à l'intérieur de la chambre de cellule (11) augmente, et il est possible d'augmenter la quantité d'électrons émis dans la chambre de cellule (11). Ainsi, même pour un échantillon de gaz présentant une concentration élevée en substances électrophiles, il est possible d'émettre une quantité suffisante d'électrons. Ceci permet d'éviter la saturation électronique et rend ainsi possible une analyse précise.
