Description
Technical field
The utility model belongs to solid-phase extraction column field, relates to a kind of constant temperature solid-phase extraction column in particular.
Background technology
Solid-phase extraction column be from chromatographic column develop a kind of for extracting, being separated, concentrated sample pretreatment device.SPE is the liquid chromatography separation principle utilizing selective absorption and selective elution.Comparatively conventional method makes fluid sample solution by adsorbent, retains wherein measured matter, then select suitable strength solvents to wash away impurity, then use the rapid wash-out measured matter of a small amount of solvent, thus reach quick separating purification and concentrated object.
In the temperature of carrying out needing in extraction process to make the material in solid-phase extraction column keep certain, to reach the effect of best efficient extraction, that solid-phase extraction column is put into larger insulating box at present, and for convenience of observing, interpolation or the material insulating box side of taking out in solid-phase extraction column need open, be convenient for people to operate, first such insulating box has larger opening, cause the temperature in insulating box larger by externally temperature influence, when ambient temperature is too high or too low, insulating box need consume higher-wattage and regulate, cause the waste of resource and cost, and insulating box takes up room larger.
Utility model content
For the deficiencies in the prior art, the utility model provides one and takes up room little, the convenient temperature controlled in solid-phase extraction column, less by externally temperature influence, the constant temperature solid-phase extraction column economized on resources.
For achieving the above object, the utility model provides following technical scheme: a kind of constant temperature solid-phase extraction column, comprise body and the sieve plate being positioned at body, the outer wall of body is provided with temperature control water pipe, temperature control water pipe is arranged from the lower to upper part spiral of body, temperature control water pipe is provided with water inlet and delivery port.
By adopting technique scheme, when extracting, by successively passing into temperature required water or other materials in temperature control water pipe by water inlet, make to be full of water in temperature control water pipe, unnecessary water will be flowed out by delivery port, make the water being full of steady temperature in temperature control water pipe all the time, and then the temperature remained constant in guarantee body, make extraction reach peak efficiency to carry out, because control temperature for directly to control on body, nearer apart from the reactive material in interior pipe, so temperature impact when ambient temperature changes in internal pipe is very little, comparatively big uncork can not be had as insulating box, heat waste is little, easy control, and just can implement without the need to larger space.
The utility model is set to further: the rectangular in cross-section of temperature control water pipe.
By adopting technique scheme, in temperature control water pipe, the temperature of water is imported within body by the sidewall of body, and the rectangular in cross-section of temperature control water pipe can ensure that the wall contacts face of temperature control water pipe and body is large, improves heat conduction efficiency, reduces heat loss.
The utility model is set to further: temperature control water pipe is provided with interval between adjacent two spiral parts of body axis direction.
By adopting technique scheme, the interval between adjacent two spiral parts makes the outside of extraction column entirety have part corner angle, convenient when taking, and avoids too smooth and shakiness of taking.
The utility model is set to further: temperature control water pipe is provided with some.
By adopting technique scheme, because temperature control water pipe is spiral uprising shape, when water flowing inside by water inlet, it has certain resistance, many temperature control water pipes, carry out water flowing simultaneously, not only can not reduce heat-conducting area, and the spiral number of turns of every bar temperature control water pipe can be reduced, reduce the resistance of every bar temperature control water pipe water flowing.
Compared with prior art, the utility model constant temperature solid-phase extraction column takes up room little, the convenient temperature controlled in solid-phase extraction column, less by externally temperature influence, economizes on resources.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, the embodiment of the utility model constant temperature solid-phase extraction column is described further.
A kind of constant temperature solid-phase extraction column, comprise body 1 and the sieve plate 3 being positioned at body 1, the outer wall of body 1 is provided with temperature control water pipe 6, temperature control water pipe 6 is arranged from the lower to upper part spiral of body 1, temperature control water pipe 6 is provided with water inlet 61 and delivery port 62, the rectangular in cross-section of temperature control water pipe 6, temperature control water pipe 6 is provided with interval between adjacent two spiral parts of body 1 axis direction, and the preferred temperature control water pipe 6 of the present embodiment is provided with some.
As shown in Figure 5, in use, water inlet 61 and delivery port 62 are coupled together by water pipe 7 by several this constant temperature solid-phase extraction columns 5 successively, be cascaded by several this constant temperature solid-phase extraction columns 5, then be connected to water tank 92 and water pump 9 by water pipe 7 again, make it form a complete circulation, in water tank 92, place temperature regulating device, can be heater strip or heating plate, the water in water tank 92 is controlled.
When extracting, the material carrying out extracting is needed to be placed on the sieve plate 3 in the body 1 of several constant temperature extracting posts, then in water tank 92, carry out by water pump 9 water extracting constant temperature, make water successively by several constant temperature solid-phase extraction columns 5, in each constant temperature solid-phase extraction column 5, first water enter temperature control water pipe 6 by water inlet 61, then carry out carrying out temperature regulation and control to the material in body 1 along temperature control water pipe 6 spiral surrounding body 1 outer wall, then flow out to water tank 92 by delivery port 62, in water tank 92, again carry out heating change temperature, circulate with this, ensure that the water in the temperature control water pipe 6 on body 1 outer wall remains same temperature, and then make the temperature constant of body 1 inside, material is reached and keeps best extraction temperature, improve extraction efficiency, water resource circulates all the time, and can not be wasted, and consume the energy few, energy loss is less, and whole loop temperature-control process is not affected by the temperature change in the external world.
The while of many temperature control water pipes 6, spiral is fixed on body 1 outer wall, then make the spiral number of turns of each temperature control water pipe 6 tail off, turning tails off, and then water pump 9 required drive reduces.
Certainly in use, also only temperature control can be carried out to a constant temperature solid-phase extraction column 5, or carry out parallel connection by between several constant temperature solid-phase extraction columns 5, namely the water inlet 61 of each constant temperature solid-phase extraction column 5 all directly connects water pump 9, and delivery port 62 is connected directly to water tank 92.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
