Abstract
A kind of testing tube of hydrogen phosphide gas, by glass outer tube, wire netting, barrier plate, indicator, glass column, concentration scale are formed, and are characterized in that mercuric chloride is reaction reagent in the indicator.Use quantitative mercuric chloride, the concentration of hydrogen phosphide in the detected gas quickly and easily in finite concentration scale scope.It is few that the present invention is rational in infrastructure, cheap, detection is disturbed by other gas.
Description
The present invention relates to a kind of gas detection product, the testing tube of hydrogen phosphide gas of more specifically saying so.
At present, both at home and abroad the detector tube of phosphine gas be substantially 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.How to make detection reaction reagent in the indicator with silver nitrate or chlorauride.Silver nitrate is made detection reaction reagent, itself instability, and sulfuretted hydrogen, arsenic hydride, antimonous hydride are to measuring serious interference; Chlorauride is a detection reaction reagent, costs an arm and a leg, and arsenic hydride, sulfuretted hydrogen also have interference to detecting.
The objective of the invention is to overcome above-mentioned is the deficiency of the detector tube of reaction reagent with silver nitrate, chlorauride, provides a kind of detection accurately, conveniently, cheap, rational in infrastructure testing tube of hydrogen phosphide gas.
For achieving the above object, the present invention is made up of glass outer tube, wire netting, barrier plate, indicator, glass column or porcelain knob, concentration scale, it is characterized in that mercuric chloride is detection reaction reagent in the indicator, wherein the weight percentage of mercuric chloride is 0.8%～1.1%, concentration scale per unit mm length represents that the concentration of hydrogen phosphide in the gas is 12～16.5ppm, and the glass outer tube diameter is 4.4～4.8 millimeters.
Fig. 1 is a structural representation of the present invention.Glass outer tube 1 of the present invention, process by glass tube, used glass tube internal diameter can be 4.4～4.8 millimeters, and pack in order in the glass tube of at one end sealing glass column 6 or porcelain knob, shelves synusia 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; Shelves synusia 3,5 usefulness polypropylene fibre are made, and its effect is to prevent 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 indicator to enter manual pump when bleeding.Indicator 4 usefulness silica gel are done carrier, and its grain size is between 60～80 orders, and mercuric chloride is detection reaction reagent, and the agent of evenly giving instruction of quantitative mercuric chloride and silica gel mechanical mixture is used.Mercuric chloride is reaction reagent, and it and phosphine gas reaction generate filemot P(HgCl)
3, after the reaction, the part of indicator 4 becomes tawny by original white, according to the 4 filemot length positions of indicator in the glass outer tube 1, can directly obtain the concentration of hydrogen phosphide 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 7 per unit mm lengths of the present invention represent that the concentration of hydrogen phosphide in the gas is 12～16.5ppm, use the concentration scale of such scope, detect the gas that phosphine concentration is lower than 3000ppm, and the detector tube size structure is reasonable.Can also indicate airintake direction on the concentration scale 7.
In above-mentioned concentration scale scope, be that concentration scale per unit millimeter represents that the concentration of hydrogen phosphide in the gas is 12～16.5ppm, when the internal diameter of glass outer tube 1 is 4.4～4.8 millimeters, the weight percentage of mercuric chloride is 0.8%～1.1% in the indicator 4 of the present invention, and this concentration range can guarantee that detecting error is lower than 15%.If the concentration of mercuric chloride reagent is lower than 0.8% or be higher than 1.1%, then detect error greater than 15%.
Use the present invention, open detector tube two ends 8,9, it is inserted in the manual pump, bleed, can directly obtain the concentration of hydrogen phosphide the detected gas according to indicator 4 variable color length from concentration scale 7 by airintake direction.
The present invention is applicable to the gas of test phosphine containing 10～3000ppm.
The present invention detects accurately, convenient, rational in infrastructure, cheap, and be subjected to the interference of other gas few.
Description of drawings:
Fig. 1 is a structural representation of the present invention, also is the synoptic diagram of embodiment.
Mark among the figure is: glass outer tube 1, wire netting 2, shelves synusia 3,5, indicator 4, glass column 6, concentration scale 7, detector tube termination 8,9.
Embodiment 1:
The glass tube of 4.5 millimeters of internal diameters is cleaned, dried, seal one 8, pack in order anistree glass column 6, barrier plate 5, indicator 4, barrier plate 3, wire netting 2 are then sealed the other end 9.Concentration scale 7 is attached on the glass outer tube 1, and its zero point is corresponding with the interface of indicator 4 and barrier plate 3.Indicator 4 is a reaction reagent with mercuric chloride, and silica gel is carrier, and its grain size is between 60～80 orders.The internal diameter of this detector tube glass outer tube is 4.5 millimeters, and concentration scale per unit mm length represents that the concentration of hydrogen phosphide in the gas is 12ppm, and the content of mercuric chloride is 0.9% in the indicator, and concentration and the actual concentrations error of measuring phosphine gas are lower than 10%.This detector tube is applicable to that detecting phosphine containing is the gas of 10～3000ppm.
Embodiment 2
To clean, oven dry is good, the glass tube that internal diameter is 4.8 millimeters is sealed an end pack in order anistree glass column 6, barrier plate 5, indicator 4, is then sealed the other end 9 at barrier plate 3, wire netting 2.Concentration scale 7 is attached on the glass outer tube 1, and its zero point is corresponding with the interface of barrier plate 3 and indicator 4.Indicator 4 is a reaction reagent with mercuric chloride, and silica gel is carrier.4.8 millimeters of this detector tube glass outer tube 1 internal diameters, concentration scale per unit mm length represent that the concentration of hydrogen phosphide in the gas is 16ppm, and the content of mercuric chloride is 1.09% in the indicator 4, and concentration and the actual concentrations error of measuring phosphine gas are lower than 10%.This detector tube is suitable for and detects phosphine containing is the gas of 10～3000ppm.
