Using standard《Soluble organic and Various Groups In Crude Oil analysis in 2008 rocks of SY/T5119》Middle column chromatography pair
Crude oil carries out Group component separation, is divided into saturated hydrocarbons, aromatic hydrocarbon, four kinds of Group Components of resin and asphalt.
Wherein, asphalitine is that asphalitine does not dissolve in normal hexane with the principle of its excess-three race's Component seperation, is relied primarily on de-
Asphalitine microparticle is retained by the physical filtering of fat cotton, is then washed out asphalitine from absorbent cotton with chloroform, is weighed.For
Avoid Group Component in the adhesion loss of inner wall of hopper, reduce consumption of organic solvent, filler neck should not typically be grown.
The separation process of asphalitine is as follows：Eliminating water remove impurity crude oil is fully dissolved first by normal hexane, then clogged with artificial
The funnel of absorbent cotton is filtered to said mixture, and the asphalitine in mixture is separated because normal hexane is not dissolved in, it
Chloroform absorbent cotton is used afterwards, asphalitine is obtained because being dissolved in chloroform, finally collect filtrate and using chromatographic column to its excess-three
Plant Group Component to be separated.
During asphalitine is separated using funnel with absorbent cotton, manually absorbent cotton need to be clogged into funnel,
In the operating process of filling absorbent cotton every time, the consolidation degree of absorbent cotton is had differences unavoidably, easily because of artificial filling absorbent cotton
Consolidation degree difference and need to carry out multiple times of filtration, so as to cause the increase of normal hexane consumption, volatilization time to increase, and cause
Because of the Various Groups In Crude Oil mass loss that multiple times of filtration operation is caused；Further, since being manually to clog, absorbent cotton mistake is clogged

Volume is slightly larger than this, then go up after the screw thread between chamber body 121 and lower chamber body 122 screws, the absorbent cotton in absorbent cotton room 120
Just fixed volume (i.e. the internal volume of absorbent cotton room 120) is compressed into, in the absorbent cotton consumption identical feelings for ensureing experiment every time
Under condition, then the volume and compression degree for testing absorbent cotton every time is also identical, also just reduces and compresses degree difference due to absorbent cotton
And the systematic error for causing, improve the accuracy of experimental data.Wherein, it is ensured that the consumption for testing its absorbent cotton every time is fixed,
Can be realized by each use quality identical absorbent cotton or volume identical absorbent cotton.When the internal volume of absorbent cotton room 120
For 796mm3, it is recommended to use absorbent cotton consumption be 0.4g～0.5g.Or, absorbent cotton volume is 120 content of absorbent cotton room
Long-pending 120%～125%.
In an optional example of the invention, as shown in Figure 2 and Figure 3, conduit 130 includes order setting from top to bottom
First reducing diameter part 131, catheter body 132, the second reducing diameter part 133 and thin footpath export department 134,131 its top of the first reducing diameter part
Internal diameter is identical with the internal diameter of lower chamber body 122, and the internal face of the internal face of the first reducing diameter part 131 and the second reducing diameter part 133 is served as reasons
The internal face of the tapered conical surface under up to, the internal face of catheter body 132 and thin footpath export department 134 is cylinder.Conduit 130 has
Have at two undergauges, respectively the first reducing diameter part 131 and the second reducing diameter part 133, by the first reducing diameter part 131 and the second reducing diameter part
133, the sectional area of absorbent cotton room 120 is gradually transition to into the sectional area of thin footpath export department 134, undergauge in the case of flow identical
Flow field change can be caused, vibrations are caused, strengthen developing result, reduce material residual, error is less；And transitional type undergauge sets twice
Meter further reduces circular bead surface type undergauge institute may caused Group Component material residual.The sectional area of thin footpath export department 134 is very
It is little, and there is certain length, in thin footpath exit, the capillary force and gravity of drop balances each other, in the situation of chromatography process low discharge
Under realize blocking the liquid of hopper outlet using capillary force, reduce air impact.
The invention allows for a kind of separation method of crude oil race studies on asphaltene, is leaked using above-mentioned Various Groups In Crude Oil analysis
