Abstract
The utility model relates to a hydrocone type extraction element of survey trimethylamine nitrogen content, including flourishing liquid pipe, U type straw, intake pipe and pressure device, flourishing liquid is managed mouth of pipe department stopper and is sealed the stopper, seals and is equipped with two holes beyond the great wall, and U type straw inserts flourishing liquid intraduct, fixes with sealing the stopper through a hole, and flourishing liquid pipe is inserted to the intake pipe through another hole that seals the stopper in, the intake pipe is connected with pressure device. The utility model discloses utilize pressure device to make flourishing liquid intraduct form pressure differential to the siphon action who produces through the U type straw of invering carries out the quick absorption transfer of automation to the extract, has reduced the loss of extract in the transfer process.
Description
Technical field
This utility model belongs to the technical field of trimethylamine nitrogen analysis, particularly relates to a kind of hydrocone type extraction element measuring trimethylamine nitrogen content.
Background technology
Trimethylamine [(CH3)3N] it is oppress based food due to the effect of antibacterial, in corrupt process, by trimethyloxamine [(CH3)3NO] reduce and produce, it is volatile basic nitrogen substance, by this material extracting in dry toluene, forms the picric acid front three amine salt of yellow, then with standard pipe colorimetric simultaneously, trimethylamine nitrogen content in sample can be recorded.
In the quality testing that Petaso produces, need the content of front three amine nitrogen is measured, in assay method, MaijelGerson reaction bulb is generally adopted to test, MaijelGerson reaction bulb self does not have the function to exterior liquid, the suction tool outside using is needed to draw, troublesome poeration, increase the loss of extracting solution.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hydrocone type extraction element measuring trimethylamine nitrogen content, it is possible to quickly outwards draw extracting solution, reduces loss.
This utility model solves its technical problem and be employed technical scheme comprise that a kind of hydrocone type extraction element measuring trimethylamine nitrogen content of offer, including liquid-holding pipe, U-shaped suction pipe, air inlet pipe and pressue device, described liquid-holding pipe mouth of pipe place is plugged with sealing plug, described sealing plug is provided with two circular cavities, described U-shaped suction pipe pours into inside liquid-holding pipe by a hole and sealing plug is fixed, described air inlet pipe is inserted in liquid-holding pipe by another hole of sealing plug, and described air inlet pipe is connected with pressue device.
As this utility model one preferred embodiment, described liquid-holding pipe is color comparison tube or test tube.
As this utility model another preferred embodiment, described U-shaped suction pipe adopts water white glass tubing.
As this utility model another preferred embodiment, described air inlet pipe is logical straight tube in being.
As this utility model another preferred embodiment, described pressue device adopts bulbs,double.
As this utility model another preferred embodiment, described sealing plug adopts rubber closure.
Beneficial effect
In this utility model, front three amine nitrogen be extracted in liquid-holding pipe to carry out, liquid-holding pipe is inserted with inverted U-shaped suction pipe and air inlet pipe respectively by the two circular cavities structure on sealing plug, air inlet pipe is connected with pressue device, liquid-holding pipe can be made internal by pressue device and air difference produces certain pressure reduction, by regulating the height of the U-shaped suction pipe mouth of pipe, utilize pressure reduction and siphon principle, it is thus possible to rapidly the extracting solution in liquid-holding pipe is outwards drawn transfer, it is to avoid manual draw the loss that transfer brings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further. Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model. In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
A kind of hydrocone type extraction element measuring trimethylamine nitrogen content as shown in Figure 1, including liquid-holding pipe 5, U-shaped suction pipe 1, air inlet pipe 2 and pressue device 4.
Liquid-holding pipe 5 adopts color comparison tube or test tube, colourless body, it is simple to content is observed, and in Petaso sample, being extracted in liquid-holding pipe 5 of front three amine nitrogen carries out. Liquid-holding pipe 5 mouth of pipe place is plugged with a sealing plug 3, and sealing plug 3 can adopt rubber closure the most frequently used in laboratory. Sealing plug 3 is provided with two circular cavities, inserts U-shaped suction pipe 1 in one of them hole, and U-shaped suction pipe 1 adopts water white glass tubing, and U-shaped suction pipe 1 is inverted, and it is internal that the VERTICAL TUBE of side inserts liquid-holding pipe 5 through sealing plug 3; Another hole is inserted into trachea 2, air inlet pipe 2 can adopt relatively short in logical straight tube. Air inlet pipe 2 is connected with pressue device 4, and this pressue device 4 is suitable to adopt bulbs,double to carry out to be pressurised into.
The hydrocone type extraction element of this mensuration trimethylamine nitrogen content is in use, first inside liquid-holding pipe 5, complete the extraction to front three amine nitrogen, insert the air inlet pipe 2 and the U-shaped suction pipe 1 that are connected to pressue device 4 more respectively, regulate the height of U-shaped suction pipe 1, pressure reduction is formed to the internal certain pressure that adds of liquid-holding pipe 5 by pressue device 4, make extracting solution be circulated into U-shaped suction pipe 1 internal, under siphonage, extracting solution liquid-holding pipe 5 within is outwards shifted and collects carry out next step and operate.
