Line is same nominal diameter.
It is retouched using process combination Fig. 1 to Fig. 6 of the glass container preparation organic mixed solution standard substance of volatility
It states.
Step S11, the weighing of the organic pure material of volatile liquid: with assay balance first ampoule of precise in order
The bottle quality of bottle moves into the first volatile liquid organic pure material in ampoule bottle, seals first ampoule bottle with sealing machine,
The gross mass of first ampoule bottle after precise sealing, the gross mass subtract the bottle quality of the first ampoule bottle and the bottle of fusing
After cap quality, the quality of the organic pure material of the first volatile liquid is obtained.In the same manner, successively that other are several
The organic pure material of mixed volatile liquid is needed to enclose in ampoule bottle respectively, and it is organic to calculate separately out each volatile liquid
The quality of pure material.
Step S12, the preparation of the organic mixed solution standard substance of volatility: to be loaded with volatile liquid organic pure by each
The ampoule bottle of substance is put into thin mouth vial 1, screws in the solid thread plug 6 of center through hole in the central, threaded through-hole 5 of bottle cap 4,
In side, tapped through hole 8 screws in the solid thread plug 9 of side through hole, then bottle cap 4 is spun on the outer of thin mouth vial 1 by its internal screw thread 3
On screw thread 2；Then the solid thread plug 6 of center through hole is removed from central tapped through hole 5, long needle applicator is used to draw as molten
The long syringe needle of the small organic pure material of liquid of the first volatility of matter, long needle applicator passes through central, threaded through-hole 5, minute hand
Head cannot encounter bottle cap 4 and thin mouth vial 1, can not be inserted into the solution in thin mouth vial 1, as close as possible to solute liquid
At above face, the organic pure material of the small liquid of the first volatility in long needle applicator is slowly injected into thin mouth vial 1
It is interior, after to be implanted, long needle applicator is taken out, the solid thread plug 6 of center through hole is spun on central, threaded through-hole 5 again
On.
Before and after the small organic pure material of liquid of the first volatility is added, thin mouth vial is weighed with assay balance respectively
1 quality, the quality of the small organic pure material of liquid of the first volatility that addition is calculated with Subtraction method.According to identical
Method sequentially adds other several organic pure materials of liquid for needing mixed volatility small, and it is organic to calculate each liquid
The quality of pure material, until whole organic pure materials of liquid are added and weigh and finish.Thin mouth vial 1 is acutely rocked, makes to be put into
Each ampoule bottle it is broken, and all ampoule bottles in contain organic pure material and thin mouth vial 1 in it is all molten
Matter is uniformly mixed.
Wherein, the content of certain organic compound is calculated as follows in mixed solution:
In formula (1):
xi,0--- the content of i-th kind of organic compound, % in mixed solution；
Purityi--- the purity of i-th kind of organic pure material, %；
mi--- the quality of i-th kind of organic pure material, g in mixed solution；
--- the gross mass of mixed solution, g.
Step S13, it the preparation of equilibration flask: is prepared according to abovementioned steps S11 and step S12, then in thin mouth vial 12
With the organic mixed solution of volatility identical in thin mouth vial 1.
Step S14, it is hollow that center through hole the connection of sealed in unit: is screwed in the central, threaded through-hole 5 of thin mouth vial 1
Round tube thread plug 7 screws in center through hole hollow circular-tube thread plug 7 in the central, threaded through-hole 5 of thin mouth vial 12；Thin mouth glass
The lower end of first round tube 71 of the lower end and thin mouth vial 12 of the first round tube 71 of glass bottle 1 reaches bottom of bottle, under the first round tube
The filter screen 11 at end is used to filter ampoule bottle fragment；The upper end of first round tube 71 of thin mouth vial 1 and ampoule bottle automatic packaging
The Liquid sample introduction pipe of machine connects, and the upper end exposure of the first round tube 71 of thin mouth vial 12 is in air.
Side through hole hollow circular-tube thread plug 10 is screwed in the side tapped through hole 8 of thin mouth vial 1, in thin mouth vial 12
Side tapped through hole 8 in screw in side through hole hollow circular-tube thread plug 10, the side through hole hollow circular-tube thread plug 10 of thin mouth vial 1
The second round tube of same root 101 is shared with the side through hole hollow circular-tube thread plug 10 of thin mouth vial 12,101 one end of the second round tube
It protrudes into thin mouth vial 1, the other end protrudes into thin mouth vial 12, and thin mouth vial 1 passes through the second round tube 101 and thin mouth glass
Glass bottle 12 is connected to.
Step S15, the distribution and encapsulation of solution: ampoule bottle automatic-packaging extracts the distribution of the solution in thin mouth vial 1
Into the ampoule bottle of 5mL volume, every bottle of 2mL solution, then with flame to the ampoule bottle Quick seal that solution is housed；It is so continuous
Solution, encapsulation are distributed, until complete soln packing finishes.
When ampoule bottle automatic-packaging extracts the solution in thin mouth vial 1, negative pressure is formed in thin mouth vial 1, by
It is connected to by the second round tube 101 with thin mouth vial 12 in thin mouth vial 1, the upper end of the first round tube 71 of thin mouth vial 12
In air, air enters from the first round tube 71 of thin mouth vial 12 at this time for exposure, forms bubble and escapes liquid level, into thin mouth
Second round tube 101 of vial 12 enters the second round tube 101 of thin mouth vial 1 via pipeline, maintains in thin mouth vial 1
Air pressure balance.
In addition, into thin mouth vial 12 air after hold-up, into thin 12 superjacent top of mouth vial
Portion space forms consistent with the air of thin 1 superjacent headspace of mouth vial；Therefore although thin mouth during packing
The liquid level of vial 1 reduces, and headspace becomes larger, but the composition of organic matter does not change in gas phase, and liquid and gas are always
Composition in equilibrium state, therefore liquid phase does not change, and the liquid composition for being assigned to ampoule bottle is kept constant, it is ensured that liquid
Uniformity between the bottle of organic mixed solution standard substance.
Explanation is compared so that three kinds prepare the method for the organic mixed solution standard substance of volatility as an example below, these three
Method is that conventional method, the method with equilibration flask packing and ampoule bottle proposed by the present invention weigh volatile organic matter respectively
With the method dispensed with equilibration flask.
