Abstract
The utility model discloses a fast high-pressure dissolving pot in the pre-processing work of trace element analysis of biological samples. A quartz heater 4 is arranged in the polytetrafluoroethene inner pot 2 of the high-pressure dissolving pot. The fast high-pressure dissolving pot causes dissolving bodies to achieve reaction conditions in a heating mode. The dissolving speed is quick (three minutes or so). The fast high-pressure dissolving pot is simple and convenient, and can be widely used in the pre-processing work of biological sample analysis of traditional Chinese medicine, foodstuff, food, agriculture, environmental protection, medicine tissues, etc.
Description
The utility model relates to the analytical equipment of biological sample, especially the biological sample analysis pre-processing device.
Used high-pressure digestion jar in biological sample analysis pre-treatments such as Chinese medicine, grain, food, medical tissue all adopts the form of outer heating to realize heating up and the insulation operation at present.Conventional method is, with sample with clear up the agent sealing and leave in the counteracting tank, with external heating modes such as baking ovens counteracting tank slowly is warmed up to temperature of reaction then.And in range of reaction temperature, be incubated a period of time, and to have suffered and clear up operating process and take more than one hour, digestion time is long.
In view of the above shortcoming of existing high-pressure digestion jar, the purpose of this utility model is, overcomes the deficiencies in the prior art, designs a kind of quick high-pressure counteracting tank, and enables to realize explosive chemical principle, reaches clearing up fast of sample.
The purpose of this utility model is to realize by following design.
By outer sleeve, in the inner chamber of the high-pressure digestion jar of compositions such as jar, interior potting lid electrical heating elements is set in the teflon, promptly adopt the internal heat type heating.The concrete practice is in the jar quartz heater to be set in teflon, and potting covered in this well heater placed, and there is a pyramidal projections well heater top and interior potting lid contact site.
After adopting above design, heater directly heats by biological sample in jar and clears up agent (H
2O
2: the HNO3) system of clearing up of Zu Chenging makes it to be able to rapid heating.Fulminating violent chemical reaction takes place in the system that causes this heating mode fast clearing up, and pressure, temperature sharp increase in jar make the organic component oxygenolysis of sample, thereby realize clearing up fast of sample.Pyramidal projections on the well heater guaranteed with himself tapering and interior potting lid between fit tightly the air-tight state in keeping jar.
The experiment proved that, the speed of clearing up that makes the utility model improves (finishing about 3 minutes) greatly, this is to use three during the last ten years from the high-pressure digestion jar, the once breakthrough aspect the shortening digestion time, and make the resolution principle of the explosive violent chemical reaction that utilizes the system of clearing up be able to specific implementation.
Accompanying drawing is a partial sectional view of the present utility model.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Consider under the higher situation of pressure the interior jar airtight further assurance that has, interior potting lid 3 plunger-type structures that are designed to have than big L/D ratio; Be the intensified safety measure, jar is provided with high-pressure safety valve.Fixed head 8, pressing plate 7, outer sleeve 1 usefulness stainless steel are made, and interior potting lid 3 and interior jar 2 are made by teflon.
Claims (2)
1, a kind of biological sample trace element analysis pre-treatment high-pressure digestion jar is made up of in outer sleeve (1), the teflon jar (2), interior potting lid (3) etc., it is characterized in that, is provided with heating in the inner chamber of interior jar (2).
2, the high-pressure digestion jar according to claim 1 is characterized in that described heating is quartz heater (4), in this well heater places on the potting lid (3); There is a pyramidal projections (5) well heater (4) top and capping (3) contact site.
