Description
Technical field
The present invention relates to the analytical chemistry instrument field, especially a kind of micro-wave digestion furnace chamber.
Background technology
In the modern analysis chemistry, the inorganic elements analytic process mainly comprises sample pre-treatments and instrument detecting two parts, and in The whole analytical process, the key of decision sample analysis speed and quality is sample pre-treatments technology 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 big, reagent dosage is many, the volatilization loss of sample cross pollution and object element or the like deficiency, and the acid mist that produces also pollutes the environment, endangers the operator.For this reason, people attempt seeking the deficiency that some can overcome these classical specimen preparations always, and have proposed microwave is used for the imagination of sample pre-treatments first in 1986.Microwave energy is incorporated into imagining once proposition of sample pre-treatments, and relevant high pressure or normal pressure micro-wave digestion/extracting process, technology and instrument promptly obtain well recognized and develop on an unprecedented scale.
Microwave is the electromagnetic wave of frequency at 300MHz-300GHz; In order to prevent that civilian microwave power from causing interference to radio communication, broadcasting, TV and radar etc., the frequency of civilian microwaves such as regulation industry in the world, scientific research, medical science and family expenses is 2450 native 5OMHz.Therefore, the employed frequency of micro-wave digestion furnace chamber all is 245OMHz basically.
At present, utilizing the micro-wave 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, the micro-wave digestion furnace chamber is following two kinds of structures often:
First kind of micro-wave 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, can have a placing hole in the side of device usually and corresponding with it movable sealing cover is set.Not enough below the micro-wave digestion furnace chamber of this structure exists:
If pressure release is not enough or untimely when using the micro-wave digestion furnace chamber; Cause internal pressure excessive; The removable cover at placing hole place is easy to popped; Because placing hole is positioned at the device side, reagent and sample in the back counteracting tank that pops can disperse towards periphery everywhere, bring great hidden danger for staff's personal safety again.
Second kind of micro-wave 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 to place counteracting tank, normally with periphery sealing welding, to guarantee that microwave does not leak.Not enough below the micro-wave digestion furnace chamber of this structure exists:
Owing to container has certain depth, on the rotating disk of container bottom, place or take out very inconvenience of counteracting tank by artificial, and counteracting tank inside is in high-temperature high-pressure state after the counteracting tank completion, inconvenient operation will be brought safety problem.
In sum, micro-wave digestion furnace chamber of the prior art is not enough below existing:
(1) when quick-fried jar of accident takes place, 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
