Outside air connects.
Further, the peristaltic pump connects the sample bottle and the void column pipe by drainage tube, and the waste liquid bottle leads to
It crosses drainage tube and connects the Solid Phase Extraction pond.
Further, the solid-phase extraction column has multiple, after one of solid-phase extraction column enrichment, next solid phase
Extraction column is connected by the connector with the void column pipe.
The device will not be influenced by the prior art discussed above, therefore wild water sample is allowed directly to be enriched in the wild,
It does not need to transport water sample back laboratory, then manual water sample is poured into void column pipe carry out solid-phase extraction column enrichment, behaviour by traditional
Make that simple and convenient, bioaccumulation efficiency is high.
