Gas mercury gold film enrichment sampling tube device

1.Air purification tube, enrichment system connection tube, mercury vapor generation bottle, acid gas absorption bottleUIt consists of a drying tube, an enrichment tube, a mercury tail gas filter, an adjustable flow meter, and an extraction pump.

2.Air purification tube: a blank enrichment tube used for purifying the air at the inlet of the mercury enrichment system pipeline.

3.Enrichment system connection pipe: polyethylene or polytetrafluoroethylene pipe, matched with the interface or connection end of the enrichment system.

4.Mercury vapor generation bottle:25 mlGlass foam bottle with a lotus shaped porous blowing head and a ground mouthed bottle stopper. Or other enrichment related factors

A reaction device that matches the system.

5.Acid gas absorption bottle:25 mlGlass foam bottle with a lotus shaped porous blowing head and a ground mouthed bottle stopper. Interior Decoration10 mlSodium hydroxide solution is used for the absorption of acidic gases in mercury enrichment systems.

​6.UType drying tube: The outer diameter of the tube is1.3 cmThe outer diameter of the branch pipe is0.5 cmThe height is10 cmofUThe glass tube with a plug is filled with anhydrous calcium chloride, and the two ends of the filler are tightly plugged with quartz wool. You can also directly purchase commercially available anhydrous calcium chloride drying tubes.

7.Mercury exhaust gas filter: Iodine containing activated carbon tube, purchased directly from the market or filled with self-made iodine activated carbon tube. Preparation of iodine activated carbon, see AppendixB.
