Abstract
A kind of testing tube of Co 2 gas is made up of glass outer tube, wire netting, barrier plate, indicator, glass column, concentration scale, is characterized in that hydrazine hydrate is a reaction reagent in the indicator, and crystal violet is developer.Use the indicator of preparation by a certain percentage, in certain concentration scale scope, can detect the content of carbon dioxide quickly and easily.The present invention is rational in infrastructure, cheap, acid-base pair detects noiseless.
Description
The present invention relates to a kind of gas detection product, the detector tube of the carbon dioxide of more specifically saying so.
At present, domestic testing tube of Co 2 gas be basically with the glass tube be shell, in wire netting, barrier plate, indicator, glass column or porcelain knob are housed, the glass tube outer wall is with the concentration scale.Activated alumina is a reaction reagent in the indicator, and thymolphthalein is a developer.This detector tube, indicator fade and are difficult for observing, and acid-base pair is measured interference, detects inaccurate.
The object of the invention is to overcome the deficiency of above-mentioned detector tube, provides a kind of detection accurately, conveniently, testing tube of Co 2 gas cheap, rational in infrastructure.
For achieving the above object, the present invention is made up of glass outer tube, wire netting, barrier plate, indicator, glass column, concentration scale, the internal diameter that it is characterized in that the glass outer tube is 4.4～4.8 millimeters, hydrazine hydrate is a detection reaction reagent in the indicator, crystal violet is developer, wherein the weight percentage of hydrazine hydrate is 22%～27%, and concentration scale scope is:
| Concentration vol% | 0.5 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Length m m | 4～5 | 7～9 | 12～15 | 17～21 | 23～27 | 28～32 | 33～38 | 39～44 | 45～49 | 50～55 | 56～63 |
Fig. 1 is a structural representation of the present invention.Glass outer tube of the present invention 1 is processed by glass tube, and used glass tube internal diameter can be 4.4～4.8 millimeters.Seal glass tube one end 8, pack in order glass column 6 or porcelain knob, barrier plate 5, indicator 4, barrier plate 3, wire netting 2 are then sealed the other end 9.Wire netting 2 is a nickel screen, and its effect is fixed stop synusia 3 and indicator 4, prevents when air-breathing that impurity from entering; Barrier plate 3,5 is used polypropylene fibre, and its effect prevents the activity of pulverulent solids indicator; Glass column 6 can be made with anistree glass bar, and the one end withstands on the inwall of glass outer tube 1 termination 8, and effect is immobilizing indicator 4 and barrier plate 5, avoids them to enter manual pump when bleeding.Silica gel is carrier in the indicator 4, and its grain size is between 60～80 orders, and hydrazine hydrate is a detection reaction reagent, and crystal violet is developer.Quantitative hydrazine hydrate, crystal violet and silica gel mix the agent of giving instruction and use.Hydrazine hydrate is met carbon dioxide reaction and is generated H
2N-NH-COOH, redox developer crystal violet becomes blue purple by original purple, and the length position according to indicator 4 blue purples in the glass outer tube 1 can directly obtain concentration of carbon dioxide the gas from concentration scale 7.Concentration scale 7 can be attached on the glass outer tube 1, also can be engraved on the glass outer tube 1, and the interface of barrier plate 3 and indicator 4 is corresponding in its zero point and the glass outer tube 1.Concentration scale scope of the present invention is such:
| Concentration vol% | 0.5 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Length m m | 4～5 | 7～9 | 12～15 | 17～21 | 23～27 | 28～32 | 33～38 | 39～44 | 45～49 | 50～55 | 56～63 |
During detection, if gas concentration lwevel is 0.5%, 4～5 millimeters on concentration scale is with the variable color of interior finger toner, and concentration of carbon dioxide is 1%, on the concentration scale 7～9 millimeters with the internal indicator variable color, below such as analogizing.Use the concentration scale of such scope, the detector tube size structure is reasonable.
The weight percentage of hydrazine hydrate is 22%～27% in the indicator 4 of the present invention, and the crystal violet weight percentage is 0.01%～0.05%, uses the concentration scale of above-mentioned scope, detects error in 10%.If the weight percentage of hydrazine hydrate is lower than 22% or be higher than 27%, then detect error greater than 10%.
Use the present invention, open two ends 8,9, it is inserted in manual pump, bleed, can directly obtain concentration of carbon dioxide the detected gas from the concentration scale according to variable color length on the concentration scale 7 according to airintake direction.
The present invention is applicable to the gas of test carbonated 0.5%～10%(vol%).
The present invention detects accurately, convenience, and rational in infrastructure, cheap, acid-base pair is measured noiseless.
