Description
Technical Field
The utility model belongs to the extraction element field especially relates to a sampling device is used in children's product toxicology detection.
Background
Toxicological tests have important effects on ensuring the safety of food, cosmetics and chemical products. The toxicity and potential harm of a chemical substance are clarified through animal experiments and human observation, so that the safety of the chemical substance used by human beings is evaluated, and a theoretical basis is provided for the establishment of preventive measures, particularly hygienic standards. The toxicity evaluation test is needed before the research and development of new cosmetics raw materials, pesticides, raw materials and chemicals and the marketing of general cosmetics raw materials, the acute oral toxicity test is the initial test stage of the product research and development, and the test result can be used as the basis for grading the toxicity of the raw materials, labeling and marking the toxicity of the raw materials and determining the dosage of a subchronic toxicity test and other toxicological tests.
The paper intelligent diaper, the sanitary pad and the like are one of the important embodiments of human science and technology. The products not only greatly facilitate the treatment of some things by people, but also provide more advanced sanitary guarantee. Compared with the conventional diaper and the paper diaper, the conventional diaper is better in breathability and much better, because it only has cloth and no water-proof substance. But it is very unfair to use the comparison result to judge the quality of the two. Because in the case of conventional diapers, one typically uses a layer of water barrier on the outside of the diaper: plastic paper which is absolutely impermeable to air. Therefore, we should compare the traditional diaper and the paper diaper with the 'full version' in which the layer has no air permeability at all, which is just fair. The good non-woven fabric for the paper diaper is lined with a material which only allows air to enter and exit but not water molecules, so that the air permeability is much better than that of a 'complete edition' traditional diaper although the air permeability cannot be compared with that of pure cloth. However, people often neglect the fairness of such a comparison, resulting in a fall-off to one side of a conventional diaper.
During the sampling of prior art, because children's product detection limit is lower, then in the sampling process, if the temperature is too high a little, will cause the volatilization of toxic organic matter easily, how to control the temperature of sampling, commentaries on classics appearance in-process, be urgent to solve.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a convenient operation, the controllable sampling device for children's product toxicology detects of temperature.
The utility model provides a technical scheme that technical problem adopted is:
a sampling device for toxicology detection of children products comprises a piston tube and a piston column, wherein the piston column is coaxially embedded in the piston tube, one end of the piston column extends out of the piston tube, and the other end of the piston tube is provided with an integrally-manufactured conical sample inlet;
the outer edge of the conical sample inlet of the piston tube is coaxially wrapped with a temperature control layer, low-temperature liquid is filled in the temperature control layer, and the temperature control layer is provided with a liquid inlet and a liquid outlet;
the piston column is hollow, ice blocks are filled in the piston column, and the end part of the piston column is sealed and covered.
Moreover, a heat insulation sleeve is sleeved outside the piston pipe.
The utility model has the advantages that:
the application provides a children's product toxicology detects uses sampling device has the low temperature sampling head, adopts refrigerant (cryogenic liquids such as frozen water) circulation around the low temperature sampling head, can carry out the low temperature treatment to the sample at the sampling initiating terminal, prevents volatilizing of poisonous substance.
The application provides a children's product toxicology detects uses sampling device inlays the dress ice-cube in the piston tube, guarantees that whole sample is in low temperature environment, effectively prevents in the sample noxious material volatilize or rotten etc..
The application provides a children's product toxicology detects uses sampling device's simple structure, and temperature control is effectual, improves and detects the precision.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
The utility model provides a children's product toxicology detects uses sampling device, includes piston tube 3, piston post 1, and the coaxial dress that inlays of piston post is in the piston tube, and one end extends the piston tube, and the conical inlet 7 that the piston tube other end was made as an organic whole.
The outer edge of the conical sample inlet of the piston tube is coaxially wrapped with a temperature control layer 6, low-temperature liquid (ice water and the like) is filled in the temperature control layer, and the temperature control layer is provided with a liquid inlet 5 and a liquid outlet 4. And the refrigerant filling ending port seals the liquid inlet and the liquid outlet.
The piston column is hollow, ice blocks 2 are filled in the piston column, and the end part of the piston column is sealed by a sealing cover 8 to prevent the ice blocks from leaking.
The liquid source of this application is generally the solution of soaking the liquid that awaits measuring, is organic solution generally, and the gaseous chromatogram or liquid chromatogram after the sample and aftertreatment go into behind the detection concentration content that detects, and then accomplish final concentration measurement.
In order to better keep the low temperature, a heat insulation sleeve can be sleeved outside the piston pipe.
The application provides a children's product toxicology detects uses sampling device's low temperature sampling head around adopts refrigerant (cryogenic liquids such as frozen water) circulation, can carry out the low temperature treatment to the sample at the sampling initiating terminal, prevents volatilizing of poisonous substance. The ice blocks are embedded in the piston tube, so that the whole sample is ensured to be in a low-temperature environment, and the volatilization or deterioration of toxic substances in the sample is effectively prevented. The utility model discloses simple structure, temperature control is effectual, improves and detects the precision.
