[0054] A specific embodiment of the present invention discloses a closed heating and digestion device, such as Figure 1 to Figure 3 As shown, the closed heating and digestion device includes: a heating table, a sample dissolution tank 1 and a fixed sealing assembly; wherein, the heating table is provided with a plurality of sample dissolution tank installation holes 2-1; the sample dissolution tank 1 includes a tank body 1-1 and The cover body 1-2, the sample dissolution tank 1 is made of polytetrafluoroethylene, the sample dissolution tank 1 is disassembled and installed in the installation hole 2-1 of the sample dissolution tank, and the heating table is used to install the sample dissolution tank in the installation hole 2-1 A plurality of sample dissolution tanks 1 in 1 are heated; the fixed sealing assembly includes a fixed cover plate 6 and a closing bolt 8, the fixed cover plate 6 is located above the heating platform and is connected with the heating platform, and the ...
Embodiment 2
[0108] Another specific embodiment of the present invention discloses an airtight heating and acid removal device, which is used in conjunction with the airtight heating and digestion device in Example 1. After the sample is digested by the airtight heating and digestion device, the The airtight heating and acid removal device of the example performs acid removal treatment on the solution in the sample dissolving tank 1 .
[0109] A kind of closed sample dissolving and acid-dispelling device of the present embodiment, such as Figure 10 to Figure 12 As shown, it includes: a sample dissolution tank 1, a heating platform and an acid vapor collection and processing assembly; wherein, the metal base 2 of the heating platform is provided with a plurality of sample dissolution tank installation holes 2-1; the acid vapor collection and processing assembly is installed on the metal base 2 above and communicated with the sample dissolution tank 1, for collecting and processing the acid...
Embodiment 3
[0134] Based on the shortcomings of the existing "inner liner + outer steel sleeve" type closed sample dissolution device, this embodiment provides an integrated closed sample dissolution system that integrates the functions of closed sample dissolution, closed acid removal and sample redissolution. The sample dissolving and redissolving functions of the closed heating and digestion device of Example 1 and the closed acid removal function of the closed heating and acid removal device of Example 2. Considering that there are many common parts in the closed heating and digestion device of Example 1 and the closed heating acid removal device of Example 2, in order to simplify the structure of the system and reduce the volume, this embodiment provides an integrated closed sample dissolving system, which integrates The functions of sample dissolution, acid removal and reconstitution are integrated to realize sample dissolution, acid vapor collection and reconstitution under closed c...
