Abstract
The invention discloses a solid-phase extraction automatic liquid-pouring buffering bottle and an application thereof. The buffering bottle and the application are characterized in that a rubber cork is arranged in the mouth of the buffering bottle; a gas suction pipe, a liquid inlet pipe, and a vent pipe are arranged on the rubber cork; a vent valve is arranged on the vent pipe; a liquid level sensor is arranged in the buffering tank and beside the liquid inlet pipe; a liquid discharge pipe is arranged on the lower part of the buffering bottle; a check valve is arranged on the liquid discharge pipe; a vacuum pump and a controller are arranged outside the buffering bottle; the controller is connected with the liquid level sensor and the vent valve. When a preset high liquid level or low liquid level is reached in the buffering tank, the controller automatically opens or closes the vent valve, such that liquid discharge is controlled or solid-phase extraction is normally carried out. With the buffering bottle and the application method, automatic liquid pouring full process is realized, such that solid-phase extraction can be carried out on-line. Therefore, efficiency is improved, and labor cost is saved.
Description
Technical field
The invention relates to experimental provision, relate in particular to a kind of surge flask that is applied to Solid-Phase Extraction and fall liquid device and application process thereof.
Background technology
In Analysis of environmental samples, along with the requirement to sample pre-treatments is more and more higher, Solid-Phase Extraction has obtained using further widely.Solid-Phase Extraction is to be based upon on traditional liquid-liquid extraction (LLE) basis, grows up gradually in conjunction with material interactional similar mix mechanism and the HPLC (high performance liquid chromatography) of widespread use at present, fixing ABC mutually among the GC (gas chromatography).Solid-phase extraction device comprises solid phase extraction column and auxiliary, and surge flask is in the auxiliary, and it plays the effect that extracts flow liquid, compensator or trimmer pressure and protection vacuum pump that takes up.
In the Solid-Phase Extraction process, need regularly manually to topple over the liquid in the surge flask, can cause following problem thus:
1 if the experimenter is not because liquid in the surge flask is in time toppled in carelessness, liquid can enter solid-phase extraction device, cause the solid-phase extraction device bottom to be in soaking state and to cause its damage, simultaneously, liquid also very easily is drawn into vacuum pump so that damages vacuum pump by exhaust tube in the bottle;
Before the 2 artificial pouring liquids, need close vacuum pump, after having toppled over, open vacuum pump again and readjust vacuum values to obtain the required speed of dripping, this process makes that Solid-Phase Extraction can not continue to carry out, and has both reduced efficient, has increased human cost again.
Summary of the invention
Purpose of the present invention, it is the shortcoming and defect that in the Solid-Phase Extraction process, needs regularly manually to topple over liquid in the surge flask that overcomes prior art, provide a kind of for the Solid-Phase Extraction process surge flask of pouring liquid automatically, to realize that the online of Solid-Phase Extraction carries out.
The present invention is achieved by following technical solution.
A kind of Solid-Phase Extraction is the surge flask of falling liquid automatically, comprise surge flask, feed tube, exhaust tube, snorkel and breather valve, it is characterized in that, be provided with bottle closure of rubber 10 in the bottleneck of surge flask 2, be provided with exhaust tube 1, feed tube 5 and snorkel 3 above the bottle closure of rubber 10, snorkel 3 is provided with breather valve 4, and surge flask 2 next doors interior, feed tube 5 are provided with liquid level sensor 6, the bottom of surge flask 2 is provided with discharging tube 7, and discharging tube 7 is provided with retaining valve 8; The outside of surge flask 2 also is provided with vacuum pump and controller 9, and controller 9 is connected with liquid level sensor 6, breather valve 4;
This Solid-Phase Extraction is the application process of the surge flask of falling liquid automatically, has following steps:
When (1) carrying out Solid-Phase Extraction, vacuum pump is by the gas in exhaust tube (1) the suction surge flask (2), and liquid enters surge flask 2 by feed tube 5, the liquid level in the liquid level sensor 6 detecting surge flasks 2, and signal passed to controller 9; When liquid level was between the high and low liquid level, controller 9 did not send instruction, and breather valve 4 keeps closed condition, and Solid-Phase Extraction continues to carry out;
(2) liquid level in surge flask 2 continues to raise, when arriving default high liquid level, liquid level sensor 6 sends signal to controller 9, controller 9 is received the breather valve of opening automatically behind the signal on the snorkel (3) 4, along with surge flask 2 internal gas pressures raise, discharge opeing mouth of pipe place pressure is greater than atmospheric pressure, and liquid is discharged outside the bottle gradually by discharging tube (7) and retaining valve 8;
(3) along with liquid level continues to reduce, when liquid level in the surge flask 2 arrived preset liquid level, liquid level sensor 6 sent signal to controller 9, controller 9 cuts out breather valve 4 after receiving signal automatically, surge flask 2 internal gas pressures reduce, and liquid stops outflow, and Solid-Phase Extraction is proceeded.
Described controller 9 is programmable logic controller (PLC), comprising comparison module.
The present invention by the automatic surge flask of the falling liquid device in the Solid-Phase Extraction process, has realized the overall process of falling liquid automatically compared with prior art, has reached the online purpose of carrying out of Solid-Phase Extraction, has improved efficient, has saved human cost.
