Claim 1:
2. The integrated machine for performing fully-automated biological evaluation and chemical analysis according to claim 1, characterized in that the pretreatment module comprises a solid phase extractor, an accelerated solvent extractor, a gel chromatograph, and a quantitative concentrator; if the sample to be analyzed is liquid, loading and enrichment of the sample to be analyzed are carried out via the solid phase extractor, and then a proper leachate is selected for elution and extraction of the multiple compounds; if the sample to be analyzed is solid, the multiple compounds are extracted from the sample to be analyzed via the accelerated solvent extractor; after a liquid extract generated by the solid phase extractor or the accelerated solvent extractor is concentrated via the quantitative concentrator to produce a liquid concentrate, the liquid concentrate is purified in the gel chromatograph to provide the mother liquor to be analyzed.
