Description
Technical field
The present invention relates to the analytical chemistry instrument field, especially a kind of microwave digestion furnace chamber.
Background technology
In the Modern Analytical Chemistry, the Elements process comprises that mainly sample pre-treatments and instrument detect two parts, in whole analytic process, determines that the key of sample analysis speed and quality is Sample Pretreatment Technique and method.Yet, the classical sample treatments such as acidolysis, alkali fusion and dry ashing that adopt usually in existing laboratory, not only have length consuming time, energy consumption is large, reagent dosage is many, the volatilization loss of sample cross pollution and object element etc. deficiency, and the acid mist that produces also pollutes the environment, endangers the operator.For this reason, people attempted seeking the deficiency that some can overcome these classical sample preparations always, and had proposed first microwave is used for the imagination of sample pre-treatments in 1986.Microwave energy is incorporated into imagining once proposition of sample pre-treatments, and relevant high pressure or microwave atmospheric digestion/extracting process, technology and instrument are namely extensively admitted and are developed on an unprecedented scale.
Microwave is that frequency is at the electromagnetic wave of 300MHz-300GHz, in order to prevent that civilian microwave power from causing interference to radio communication, broadcasting, TV and radar etc., the frequency of the civilian microwaves such as in the world regulation industry, scientific research, medical science and family expenses is 2450 native 5OMHz.Therefore, the employed frequency of microwave digestion furnace chamber all is 245OMHz basically.
At present, utilizing microwave digestion furnace chamber that the analytical chemistry sample is carried out pre-treatment has become a kind of important technical, and in the prior art, microwave digestion furnace chamber often is following two kinds of structures:
The first microwave digestion furnace chamber is hollow rectangular parallelepiped closed container; be that bottom surface and tank skin are affixed for sealing on the cavity; the a plurality of counteracting tanks that fill reagent and sample are placed in the cavity bottom the inside; for the ease of the putting into or taking out of counteracting tank, usually can have in the side of device one and place mouthful and arrange corresponding with it movable sealing cover.The microwave digestion furnace chamber of this structure has the following disadvantages:
If pressure release is not enough or untimely when using microwave digestion furnace chamber, cause internal pressure excessive, placing mouthful removable cover at place is easy to be popped, be positioned at the device side because place mouth again, the reagent and the sample that pop in the rear counteracting tank can disperse towards periphery everywhere, bring great hidden danger for staff's personal safety.
The second microwave digestion furnace chamber is the hollow cylindrical container of upper and lower opening, the upper bottom surface opening is for the ease of counteracting tank being put into the digestion instrument bottom, bottom surface support rotating disk is used for placing counteracting tank, normally with the peripheral sealing welding, to guarantee that microwave does not leak.The microwave digestion furnace chamber of this structure has the following disadvantages:
Because container has certain depth, by manually placing or to take out counteracting tank very inconvenient at the rotating disk of container bottom, and counteracting tank finish after counteracting tank inside be in high-temperature high-pressure state, inconvenient operation will be brought safety problem.
In sum, microwave digestion furnace chamber of the prior art has the following disadvantages:
(1) unexpected when quick-fried tank occurs, when the furnace chamber internal pressure is excessive, bring great hidden danger can for staff's personal safety;
(2) counteracting tank is difficult for putting into or withdrawing device, and particularly taking out operation has potential safety hazard.
Summary of the invention
