Embodiment 1

[0043] This embodiment provides a microwave digestion system, such as figure 1 As shown, it includes: a closed container 1 and a digestion tank 2. The airtight container 1 is used to have a reaction environment including high temperature and high pressure in the cavity of the airtight container 1 during microwave digestion, and the reaction conditions such as temperature and pressure in the airtight container 1 are consistent. The digestion tank 2 is connected and placed in the cavity of the airtight container 1. The digestion tank 2 is a non-sealed structure. The digestion tank 2 communicates with the cavity of the airtight container 1. unanimous.

[0044] The airtight container 1 can be made of non-metallic material, which can penetrate microwaves and can be placed in the microwave cavity 3 . The airtight container 1 can also be made of metal materials and used directly as a microwave cavity, and microwaves directly enter the airtight container to heat the sample reagent. ...

Embodiment 2

[0051] This embodiment provides a microwave digestion method, which can be applied to the microwave digestion system in the above-mentioned embodiment 1. The microwave digestion method includes the following steps:

[0052] The first step is to put the sample reagent into the tank body of the digestion tank, and cover the tank cover non-sealed; cover the tank cover to prevent the water vapor in the closed container from condensing and dripping into the digestion tank to cause pollution;

[0053] The second step is to place the digestion tank in a closed container;

[0054] The third step is to add a certain amount of solution, such as water, into the airtight container, and the liquid level of the solution is lower than the tank cover of the digestion tank;

[0055] The fourth step is to heat the airtight container.

[0056] The above microwave digestion method, by placing the non-sealed digestion tank in the airtight container, makes the reaction conditions such as temperatu...

Abstract

The invention discloses a microwave digestion system and method, which belong to the technical field of microwave digestion equipment, wherein the microwave digestion system includes a closed container, and the cavity of the closed container has a reaction environment including high temperature and high pressure during microwave digestion; the digestion tank, The connection is placed in the cavity of the airtight container, the digestion tank is a non-sealed structure, and the digestion tank communicates with the cavity of the airtight container. The reaction conditions such as temperature and pressure among various digestion tanks of the present invention can be kept highly consistent, and can meet the requirements of ultra-high pressure digestion.

Description

technical field [0001] The invention relates to the technical field of microwave digestion equipment, in particular to a microwave digestion system and method. Background technique [0002] Microwave digestion usually refers to the wet digestion that uses microwaves to heat the digestion solution (various acids, some lyes, and salts) and samples in a closed container, so that various samples can be quickly dissolved under high temperature and pressurized conditions. [0003] For example, Chinese patent CN204988855U discloses a microwave digestion instrument, which includes a box body, a turntable, a drive mechanism, a plurality of digestion tanks and a rupture disc. Equipped with pressing parts, the sealing effect is better, and the digestion tank has high temperature and high pressure during digestion. [0004] For another example, Chinese patent CN204666432U discloses a multi-channel sealed microwave digestion system, which includes a combined tank frame, and at least two...
