Abstract
The utility model relates to a preprocessor integrated with extraction, filtration and on-computer test, which is used for organic matter test. The preprocessor comprises a container, a bottle cap, an inner pipe and a filtering membrane, wherein the bottle cap is covered at the upper end of the container; the inner pipe is placed in the container and is used for storing sample extraction solution; and the filtering membrane is arranged at the lower end of the inner pipe and is used for filtering the sample extraction solution. When the preprocessor integrated with extraction, filtration and on-computer test is used for sample preprocessing in chromatographic analysis, only a little sample is needed; moreover, the dosage of the solution is less, and the operation method is simple, fast and practical; in addition, no solution transfer step in the middle, therefore, the process loss is small.
Description
[technical field]
The utility model relates to a kind of front processor, and particularly a kind of treasury that is used for organic matter test is got, filtered and last machine is tested 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 chromatography, the ultrasonic extraction method was the simplest, pre-treating method the most fast.Conventional ultrasonic extraction method operating procedure is, quantitatively take by weighing sample (being generally 1-2g), add an amount of solvent (being generally 15-20ml), put into ultrasonic 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]
Based on above-mentioned, the utility model is to solve the deficiencies in the prior art, get, filter and last machine is tested front processor in one and propose a kind of treasury that is used for organic matter test, when carrying out pre-treatment with this front processor, only need small amount of sample, and solvent load is few, method of operating is simple, quick, practical, the centre does not have the solvent transfer step, process loss is little.
The treasury that the utility model provides is used for the organic matter test get, filter and last machine in the front processor of one, it comprises:
Container (2);
Be located at the bottle cap (1) that is covered on container (2) upper port;
Be located at and be positioned over the interior pipe (3) that is used to deposit sample extraction solution in the container (2);
Be located at the filter membrane (4) that interior pipe (3) lower port is used for the filtered sample extraction solution.
Described container (2) is a glass material, and its internal diameter is 1cm, and volume is 2mL, and bottleneck is an external thread structure.
Described bottle cap (1) is the internal thread bottle cap of the interior dottle pin of band of ordinary construction.
Pipe (3) is the hollow circular-tube or the rectangular tube of glass material in described, and internal diameter is 3-5mm.
Described filter membrane (4) is nylon-type, the filter membrane that mixes fine class, polysulfones, fluorine material type or PP type, and its aperture is 0.25um-5um.
When carrying out the organic matter test: quantitatively take by weighing small amount of sample (being generally 0.01g-0.1g) and put into container (2), and quantitatively pipette suitable solvent (being generally 0.8mL-1.5mL) in container (2), bottle cap (1) is threaded onto the upper port (will screw) of container (2), the container (2) that covers bottle cap is put into ultrasonic instrument carry out ultrasonic extraction; After ultrasonic extraction finishes, the bottle cap of outwarding winding (1), the interior pipe (3) that filter membrane (4) will be installed is put in the container (2), and filter membrane (4) will be immersed under the liquid level.Internally managing (3) by interior pipe (3) upper end open place slowly bleeds, solution (extraction solution of sample) promptly enters in the interior pipe (3) from container (2), treats that liquid level in the interior pipe (3) rises to from the bottom of the bottle during height 0.5cm, stops to bleed, cover bottle cap (1), be put on the instrument and test.
The treasury that is used for the organic matter test that the utility model relates to gets, filters and last machine is in the advantage of the front processor of one:
Front processor of the present utility model be a kind of treasury that is used for organic matter test get, filter and last machine in the front processor of one, with this front processor when sample pre-treatments is carried out in chromatography, only need small amount of sample, and solvent load is few, method of operating is simple, quick, practical, the centre does not have the solvent transfer step, and the process loss is little.
