Detailed Description
The design concept of the invention is as follows:
the applicant finds out through research that: combustible ice in the ocean takes millions of years to accumulate and gradually form. The sites of formation all occur in the pores of the deposit, and the increasing amount of combustible ice during formation gradually and slowly generates very high pressure on the accumulated deposit, which pressure increases as the combustible ice grows. And then the high-pressure pore water is used for soaking, so that the mutual compaction degree is very high. Combustible ice is continuously generated in the pores of the combustible ice, the volume is increased, the pressure of the deposit is further increased, the volume of the deposit is reduced, and the deposit is further compacted. So that the deposit has two characteristics different from other samples, namely super-strong hydrophilicity and super-strong adhesive force. That is, when the sediment meets water, the sediment is very easy to absorb moisture, and when the sediment is pretreated before the volatile element test, the sediment samples are also very easy to adhere together, so that the effect of contacting the digestion solution in the samples is poor.
In the process of testing pretreatment of volatile elements, multiple experiments show that the best solution is to continuously rotate, shake and the like during pretreatment.
