Description
Technical field
The utility model relates to a kind of gas volume measurement mechanism, is specifically related to the device that a kind of method by air scavenge liquid carrys out measurement gas volume.
Background technology
Gas volume measurement mechanism is often used in chemical experiment.Current people commonly use the volume of the gas that three kinds of methods are come to produce in experiments of measuring: fluid-discharge therapy, combustion method, solution absorption method.Fluid-discharge therapy is a kind of method that people the most often use, on the one hand, because the gas major part that we often measure can use fluid-discharge therapy to measure; On the other hand, combustion method in processing safety, solution absorption method all more or less existing defects in operation convenience.But the device that the drainage that we use in fact now surveys gas volume also has several unavoidable problem, first more piston, the bend pipe using band boring of such as traditional device, will join plug, boring etc., both time-consuming bothersome, again likely poor air-tightness; Some devices are also had to there is the problem of read untrue, and the shortcoming of their ubiquity troublesome poeration.Therefore, necessary invention a kind of simple to operate, impermeability good, accuracy of reading, practical gas volume measurement mechanism.
Summary of the invention
The purpose of this utility model is the deficiency existed for existing gas volume measurement mechanism, there is provided a kind of simple to operate, impermeability good, accuracy of reading, practical gas volume measurement mechanism, it can under lab be built at any time or split, and carries out cubing by the existing gas being insoluble to this liquid to reaction generation of liquid light pine nut changed inside glass column.
For achieving the above object, the gas volume measurement mechanism of the utility model design, comprise chromatography glass column, acid buret and round-bottomed flask, it is characterized in that described acid buret is inverted in chromatography glass column, acid buret is connected with round-bottomed flask by conduit.
The utility model has the advantage of can under lab with taking with tearing open, by changing, liquid light pine nut inside glass column is existing carries out cubing to the gas being insoluble to this liquid that reaction produces, and simple to operate, impermeability good, accuracy of reading.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: 1. chromatography glass column; 2. acid buret; 3. round-bottomed flask; 4. conduit.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Gas volume measurement mechanism as shown in Figure 1, comprise a chromatography glass column 1, acid buret 2 and a round-bottomed flask 3, chromatography glass column 1 is fixed placement straight up, acid buret 2 is inverted in glass columns, also be vertical placement, and be connected with round-bottomed flask by acid buret with a conduit 4, each junction all seals.Wherein acid buret and chromatography glass column composition measurement component, round-bottomed flask is reaction unit, and conduit is UNICOM's parts.
Principle of work of the present utility model and process as follows: the part that in this gas volume measurement mechanism, acid buret and chromatography glass column form is equivalent to a linker, the liquid level outside acid buret and in chromatography glass column can be regulated by the cock below turn chromatography glass column, when liquid level is equal, according to the pressure equal (atmospheric pressure) outside the known acid buret of law of connected vessels and in chromatography glass column.We are according to Amagat law in addition, the cumulative volume of the low-pressure combination of gasses equals the volume sum of each component at identical temperature and stagnation pressure condition, due to the constancy of volume of the air in round-bottomed flask and conduit, so when twice reading, the change (difference of twice reading) of volume is the volume of surveyed gas.
When measuring, after reactant is put into round-bottomed flask, immediately by bottle stopper jam-pack, and insert the conduit of band syringe needle, now acid buret is built with the liquid (the inconsistent liquid of gas that this liquid selective is a kind of with measured) of certain altitude, acid buret outer (in chromatography glass column) too, keeps two liquid levels to maintain an equal level.If uneven, below adjustable chromatography glass column, partially liq is released in cock, until inside and outside liquid level maintains an equal level.Then cock is closed, record the liquid level scale in now acid buret.Now flask, conduit and acid buret are an enclosed system, and air pressure is an atmospheric pressure.Slowly start have gas to produce when reacting in round-bottomed flask, liquid level in acid buret can slowly decline, because the liquid in air scavenge part pipe.At this moment, the liquid level in the chromatography glass column of outside can raise, and will open cock below chromatography glass column at once, careful releasing partially liq, make the liquid level in the liquid level of outside and acid buret equal, so just making gas atmosphere in system consistent with the air pressure of outside, is all an atmospheric pressure.By the liquid level scale in set time record buret, and subtract each other with initial scale above and be the volume (air pressure is an atmospheric pressure) that this time period releases gas.
