Person's instantaneous concentration, it is not accurate enough.This equipment uses passive sampling, will not be by time, burst equivalent to a kind of in-situ enrichment technology
The limitation of the factors such as event, while actual sample can also be avoided to be transferred back in lab process and changed, relatively actively sample
Technology is highly efficient cheap.
In the technology of current collection Organic substance in water, enrichment phase is generally macromolecule organic phase, and polarity is weaker, extracter
Reason is based on " similar to mix ", the enrichments for being directed to hydrophobic organic compound more.And for being enriched with the technology of Hydrophilic polar materials
It is less, need to collect a large amount of water bodys during sampling into being enriched with again behind laboratory, and applicable pellicle is few, by environmental factor
Influence it is big, the rate of recovery is relatively low and unstable, costly, and program is complicated.The present apparatus can realize that original place samples, Simple portable,
And efficiently concentrating is carried out to Hydrophilic polar materials in water body using recoverable polar organic matter adsorbed film, improve for richness
Collect the deficiency of Hydrophilic polar pollutant technology.
