| 摘要 |
The invention relates to means of chemical analysis in gas chromatography and for injection analysis. Electro-chemical gas sensor consists of gas chamber with wetted indicator electrode made of carbon material and second chamber with comparison electrode made of carbon material, this is filled with electrolyte, the chambers are divided with flat porous electrolytic key. Electro-chemical gas sensor has space over indicator electrode in gas chamber, as slot, there supplementary electrode is placed. Second chamber is made flow-through and comparison electrode is arranged as plug made of porous carbon material. The invention increases sensitivity and possibility of use of electro=chemical gas sensors. |
