Embodiment
Further describe the present invention below in conjunction with the drawings and specific embodiments.
Embodiment 1
The invention provides a kind of chromatogram bottle as shown in Figures 1 and 2, comprise bottleneck 1 and bottle 5, bottle 5 is provided with induction pipe 7 and outlet 2 and outlet 3, is provided with coupon in the bottle intracavity 4; Described coupon one end is connected with one of them outlet 3, and the other end communicates with induction pipe 2 and chromatogram bottle bottle intracavity 4.
Described coupon comprises successively three sections of the connecting pipes of the B pipe, A pipe, B pipe and the A pipe that connect; Described B pipe is connected with induction pipe 7, and the B pipe is provided with opening and communicates with bottle intracavity 4; The A pipe is connected with an outlet 2.Induction pipe, A pipe, B pipe, connecting pipe and outlet can adopt conventional glass tube processing technology one to stretch and form, and insert bottle intracavity with reference to the method for built-in bottle of existing vial or handicraft.
The invention provides a size Selection scheme: described A bore is 1.0～2.5mm, and external diameter is 2.5～3.5mm.
Described B bore is 3.5～5.5mm, and external diameter is 5.5～6.5mm.
Described chromatogram bottle bottleneck height is 6～8mm, and internal diameter is 6～7mm, and external diameter is 7～8mm.
Described chromatogram bottle bottle height is 30～32mm, and internal diameter is 9～10mm, and external diameter is 11～12mm.
Described chromatogram bottle induction pipe and outlet internal diameter are 1.0～2.5mm, and external diameter is 2.5～3.5mm.
Sample is managed by the B that induction pipe 7 flows into coupon, and the connecting pipe of flowing through from top to bottom enters the A pipe, and the A pipe connects an outlet 2, and sample from then on outlet 2 flows out; Sample flow in the A pipe should be less than the sample flow in the induction pipe, and the sample that has more will be overflowed by the B tube opening and enter in the outer inner chamber 4 of bottle coupon, and the sample in the inner chamber can flow out from another outlet 3.
Present embodiment provides an application of described chromatogram bottle.
As shown in Figure 3, through sample process de-bubble colorimetric pool 8 de-bubbles that Continuous Flow Analysis instrument (CFA) chemical reaction units 6 flows out, colorimetric pool 8 is provided with waste pipe 9, and the sample after de-bubble flows to chromatogram bottle through peristaltic pump 14 suctions from colorimetric pool.Also can adopt not de-bubble colorimetric pool, not need to establish waste pipe and peristaltic pump this moment, sample by flowing out in the colorimetric pool, relies on the expulsive force of CFA itself to flow to chromatogram bottle from colorimetric pool with bubble.Sample flows into B pipe in the chromatogram bottle, connecting pipe and A pipe from chromatogram bottle induction pipe 7, and the bottleneck 1 of chromatogram bottle opens wide, and the liquid chromatography sample introduction needle is drawn sample by the chromatogram bottle bottleneck, and its method of operating is identical with the sampling mode of existing liquid phase chromatographic analysis method.
The A pipe is connected with an outlet 2, and outlet 2 is connected with peristaltic pump 10, and air and unnecessary waste liquid are discharged by waste pipe 11 through peristaltic pump 10 suctions; Can not suck bubble for effectively guaranteeing in the A pipe, the flow of sample is less than the flow of sample in the induction pipe in the A pipe, therefore an outlet and a cover waste discharge device can not be satisfied the demand, in waste pipe 11 drain samples, part sample and may will overflowing from the B pipe by the bubble that analyser brings, flow into the outer space of bottle intracavity 4 coupons, and can flow out from another outlet 3, outlet 3 is connected with another set of waste discharge device, is discharged by waste pipe 13 through peristaltic pump 12 suctions when waste liquid is expired to outlet 3 mouths of pipe.The sample flow direction is shown in arrow in the accompanying drawing 3.
In the chromatogram bottle test liquid less than the time, outlet 3 places can suck air and bubble.Adopt peristaltic pump 10 suctions, guarantee the flow of the flow of outlet 2 place's moving phases, prevent that air is inhaled in the outlet 2, and have only sample to discharge through waste pipe 11 less than induction pipe 7 place's moving phases; And the sample that has more will be overflowed by the B tube opening, enters in the outer inner chamber of bottle coupon.Peristaltic pump 12 and peristaltic pump 10 should be worked simultaneously, and guarantee the flow of the flow sum of two outlet place moving phases greater than induction pipe 7 place's moving phases, thereby guarantee that the unnecessary sample in the bottle intracavity in time discharges, and sample can not come out from spill-over in the chromatogram bottle.
