Abstract
The utility model discloses the surge flasks that a kind of gas dry for Solid Phase Extraction and increase buffering effect are integrated, including former surge flask, former surge flask is equipped with water inlet pipe and gas outlet, the original surge flask connects a newly-increased surge flask, it is connected with rubber snorkel between the gas outlet of former surge flask and newly-increased surge flask air inlet, it is provided with bottle closure of rubber in newly-increased surge flask bottleneck, there is the air drying agent parcel to be hung from bottleneck with filament in bottle, newly-increased surge flask gas outlet is connected with the vacuum pump of outside setting.Air of the utility model surge flask drying into vacuum pump; preventing vapor from entering vacuum pump makes the service life of pump reduce; surge flask volume is increased, prevents from forgetting the cause of falling waste liquid pump because of inadvertent or extraction equipment is damaged, protective effect is played to vacuum pump and solid-phase extraction device.
Description
Technical field
The utility model is related to Solid Phase Extraction fields, and in particular to a kind of applied to the collection gas dry of Solid Phase Extraction and increasing
The surge flask that big buffering effect is integrated.
Background technology
With the development of science and technology, application of the modern separation technology in sample preparation is increasingly subject to the concern of people,
Sample pretreatment has become an important branch in chemistry especially analytical chemistry field.Solid phase extraction techniques are with its operation letter
Single, convenient advantage, is more and more widely used.It is the conjugate phase based on traditional gold-liquid extraction
Stationary phase basic knowledge in similar the mix mechanism and current widely used high performance liquid chromatography and gas-chromatography of interaction
It has gradually developed.Solid-phase extraction device includes solid phase extraction column and auxiliary, and surge flask is one in auxiliary, it is played
Collect extract liquor, compensator or trimmer pressure and the effect for protecting vacuum pump.
It needs manually periodically to topple over liquid in surge flask in extraction process, will appear problems in operation：
1 carries out certain time when extraction, and drop is will appear in surge flask gas outlet and pipe, and vacuum pump can also enter water and steam
Gas, due to working long hours and excessive vapor enters, vacuum pump easily generates heat, is easily damaged.
If 2 experimenters are not because inadvertent topples over liquid in surge flask in time, liquid can enter solid-phase extraction device, lead
Solid-phase extraction device bottom is caused to lead to its damage in soaking state, meanwhile, liquid is also easily taken out by exhaust tube in bottle
Enter vacuum pump so that damage vacuum pump.
Utility model content
In order to solve the problems in the existing technology, the utility model provides a kind of gas dry for Solid Phase Extraction
With increase the surge flask that is integrated of buffering effect, when overcoming that extraction carries out in the prior art, work long hours and excessive vapor
Into the easily impaired problem of vacuum pump.
The technical solution of the utility model is：A kind of gas dry for Solid Phase Extraction and increase buffering effect are integrated
Surge flask, including former surge flask, former surge flask is equipped with water inlet pipe and gas outlet, the one newly-increased buffering of original surge flask connection
Bottle, rubber snorkel is connected between the gas outlet of former surge flask and newly-increased surge flask air inlet, increases setting in surge flask bottleneck newly
There is bottle closure of rubber, there is the air drying agent parcel to be hung from bottleneck with filament in bottle, increases surge flask gas outlet newly and be arranged with external
Vacuum pump be connected.
The air drying agent is silica-gel desiccant, can thermal dehydration reuse；The amount of dry parcel regarding bottle volume and
It is fixed.
The beneficial effects of the utility model are：The drying of the utility model surge flask prevents water from steaming into the air of vacuum pump
Gas, which enters vacuum pump, makes the service life of pump reduce, and increases surge flask volume, prevent because inadvertent forget the cause of falling waste liquid pump or
Extraction equipment is damaged, and protective effect is played to vacuum pump and solid-phase extraction device.
Description of the drawings
Fig. 1 is that the utility model integrates gas dry and increases the structural schematic diagram of the surge flask of buffering effect；
Wherein：A- original surge flasks, B- increase surge flask newly, 1- water inlet pipes, 2- outlets (water) mouth, 3- air inlets (water) mouth, and 4- is dry
Dry parcel, 5- bottle closure of rubber, the gas outlets 6-.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Utility model device includes：Snorkel between two surge flasks, water inlet pipe, bottles is air-dried parcel, surge flask
A is the drying buffer bottle increased newly on the basis of former surge flask B, and the water inlet pipe 1 of former surge flask and gas outlet 2, gas outlet 2 are delayed with newly-increased
It rushes between bottle air inlet 3 and is connected with rubber snorkel, be provided with bottle closure of rubber 5 in newly-increased surge flask bottleneck, have in bottle from bottleneck and use
The air drying agent parcel 4 that filament hangs, newly-increased surge flask gas outlet 6 are connected with the vacuum pump of outside setting.The air is dry
Drying prescription is silica-gel desiccant, can thermal dehydration reuse；The amount of dry parcel is depending on bottle volume.
Vacuum pump is opened, and when Solid Phase Extraction is normally carried out, waste liquid enters from the water inlet pipe of surge flask B in bottle, and gas is through going out
Tracheae 2 and newly-increased surge flask A air inlet pipe 3 enter A, and gas approach dries small coating drying, from vacuum of the gas outlet 6 outside
Pump.When operating personnel are because of inadvertent, surge flask B is filled with liquid not to be toppled in time, and surge flask A can flow into part by air inlet pipe 3
Liquid, escape pipe 2 is the water outlet of surge flask B at this time, and air inlet pipe 3 is surge flask A water inlets, and surge flask A can play certain
The effect of buffering, by itself practice experience for, general B bottle be filled with liquid later very short a period of time be just found, so not
It must worry that liquid excessively impregnates dry parcel in surge flask A, outwells the liquid entered in surge flask A if this occurs,
Replace dry parcel.
Although the utility model is described above in conjunction with attached drawing, the utility model is not limited to above-mentioned
Specific implementation mode, the above mentioned embodiment is only schematical, is not restrictive, the ordinary skill of this field
Personnel are not departing from the utility model aims and scope of the claimed protection under the enlightenment of the utility model,
Many forms can also be made, these are belonged within the scope of protection of the utility model.
