Description
Technical field
The utility model relates to a kind of treasury that is used for organism test and gets and filter front processor in one.
Background technology
Ultrasonic extraction (Ultrasound extraction) technology is a kind of new separation technology that development in recent years is got up, and compares with the abstraction technique of routine, and the ultrasonic extraction technology has characteristics such as quick, inexpensive, safe, efficient.At present, when sample pre-treatments was carried out in stratographic analysis, the ultrasonic extraction method was the simplest, pre-treating method the most fast.Conventional ultrasonic extraction method operation steps is, quantitatively take by weighing sample (being generally 1-2g), add an amount of solvent (being generally 15-20ml), put into ultrasound wave and carry out ultrasonic Extraction, behind ultrasonic the finishing, filter, mother liquor is transferred in the volumetric flask, and be settled to scale (being generally 25ml or 50ml) with solvent, only get at last and seldom measure solution (being no more than 1ml usually) and carry out instrumental analysis.The shortcoming of this operation is, on the one hand, the intermediate filtered step will be used a sets filtering device in addition, and during also comprise the solution transfer step, can cause sample loss unavoidably, thereby influence the accuracy of final test; On the other hand; this pre-treatment means need be settled in the volumetric flask; required quantity of solvent is relatively large; the not enough 1ml of quantity of solvent that finally is used for the machine test; and really in test, play a role have only several microlitres; excessive solution will not only cause cost waste as waste disposal, more increase the weight of the burden of environmental protection.
Summary of the invention
The utility model purpose is to provide a kind of treasury that is used for the organism test to get and filter front processor in one, with this processor when pre-treatment is carried out in organic stratographic analysis, only need small amount of sample, and solvent load is few, method of operating is simple, quick, practical, process loss is little.
The front processor in one is got and filtered to the treasury that is used for the organism test that the utility model provides, and it comprises:
One container 2;
The one vertical filtering membrane 3 that is positioned within the described container 2 and described container 2 is divided into first container 4 and second container 5;
Be covered on the bottle cap 1 of described first container, 4 upper port and second container, 5 upper port simultaneously;
Be located at the draft tube 7 on the bottle cap 1 that is covered on described first container, 4 upper port;
Be located at the exhaust tube 6 on the bottle cap 1 that is covered on described second container, 5 upper port.
Described container 2 is the container of glass material, and its volume is 2-8ml.
Described filtering membrane 3 is nylon-type, mixes the filtering membrane of fine class, polysulfones, fluorine material type or polypropylene class, and its aperture is 0.2-5um.
When organism is tested: quantitatively take by weighing small amount of sample (being generally 0.01g-0.1g) and put into first container 4, and quantitatively (being generally 1-5ml) pipettes suitable solvent in first container 4, the conventional bottle cap of suitable size is threaded onto the upper port (will screw) of described container 2, described container 2 is put into ultrasonic instrument carry out ultrasonic extraction; After ultrasonic extraction finishes, outward winding and remove conventional bottle cap; Upper port spiral cover upper bottle cover 1 in described container 2, slowly inflate by 7 pairs first containers 4 of air intake opening, or slowly bleed by 6 pairs second containers 5 of exhaust tube, solution (mixed liquor of sample and solvent) in first container 4 promptly enters in second container 5 from first container 4, when treating that first container, 4 interior solution all enter second container 5, stop to bleed; Can directly be transferred to the instrument test that carries out sample in the conventional Agilent sample introduction bottle with the solution in second container 5 this moment.
The treasury that is used for the organism test of the present utility model is got and is filtered in the advantage of the front processor of one and is:
Front processor of the present utility model is that the front processor in one is got, filtered to a kind of treasury that is used for the organism test, with this processor when sample pre-treatments is carried out in stratographic analysis, only need small amount of sample, and solvent load is few, method of operating is simple, quick, practical, process loss is little.
