Laboratory is filtered, and not only needs to take substantial amounts of container and space, and water sample is sent out due to being influenceed by external environmental condition
Raw be varied such that can not obtain information in situ.This just needs researcher to complete sample collection work in scene in the wild.
The suction filtration system used at present is broadly divided into two classes：One kind is one or multi-joint suction filtration/filter system, uses this
Class filters particle suspensions/miniature organism that system can only obtain a kind of particle diameter or pore size every time.Therefore, such filters system
System is either manually or electronic all relatively time-consuming.Also a kind of multistage filtering formed that is successively stacked together by filter membrane
System, it is mainly used in effectively removing water sample particle suspensions with analysis water-like or solution using this kind of filtration system, rather than is
Obtain particle suspensions/miniature organism of different-grain diameter or pore size.The sample volume thus filtered using such system
It is smaller, typically not greater than 100ml.In addition, the water sample of different steps can not be obtained using such filter, and filters concrete water quality
Need to maintain higher negative pressure of vacuum just to can guarantee that water sample passes through step filter membrane when big, so as to limit it in hydrosphere research
