Description
Technical field
The present invention relates to the sample preparation in the fields such as ocean, water environment, biological medicine, chemistry, especially a kind of batch system
The device of standby small size filtrate sample.
Background technology
Filtering is the most common pretreatment mode in water sample analysis detection process, realizes that solid phase is outstanding in water sample by filtering
The separation of float matter and liquid phase soluble matter, by the selection to filter medium, such as：The filter membrane or bolting silk of different pore size filters
Deng realizing different separating effects, meet the suspended matter sample or filtrate sample that different detection projects require to prepare.It is logical
Often, if being detection target with the suspended matter in water sample, such as：Chlorophyll, particulate organic carbon, particulate organic nitrogen etc., then with filtering after
Filter medium be sample；If being to detect target, such as dissolved organic carbon, nutritive salt, heavy metal with the soluble matter in water sample, then
Using filtered filtrate as sample.Suction filtration is most common filter type in practical operation, it is formed negative by vacuum plant
Pressure accelerates filter course.A set of basic Suction filtration device includes the main portion such as specimen cup, filter tunnel, bottle,suction and vacuum pump
Part.Some specially designed Suction filtration devices are designed to the pattern in parallel or series of multigroup above-mentioned component, to realize multiple water
The synchronous filtering of sample improves efficiency, saves sample processing time.However, this multi-joint Suction filtration device is typically to be directed to collect
The demand of filter medium and design.
Currently, the preparation of filtrate sample usually passes through two kinds of approach：1）Directly acquisition prepares suspended matter using Suction filtration device
The filtrate formed when sample.The advantages of this processing mode, is：Processing procedure can utilize power equipment to assist, and save manpower,
The efficiency of sample treatment can be greatly improved by multi-joint mode simultaneously.Its shortcoming is that：First, the filtrate for filtering formation is collected
In bottle,suction, since bottle,suction needs to reuse, the risk of sample room cross contamination is higher, often handles a sample
It is required for, to bottle,suction rinse repeatedly, increasing operation link；Secondly, the aperture specification for the filter medium of separating suspension
It is possible that being mismatched with the requirement for preparing filtrate sample, such as uses and have more tiny particles content when the filter membrane of large aperture through filtering
Medium enters filtrate, and the testing result for soluble matter is caused error occur.This processing mode is commonly available to detection essence
Spend occasion of less demanding and that sample size is more.2）Using disposable syringe and syringe needle filter, pass through the side of manual press filtration
Formula carries out the preparation of filtrate sample.The advantages of this processing mode, is：The contaminated risk of filtrate sample can effectively be reduced.Its
Disadvantage is：Processing procedure needs manually to carry out one by one, can not efficiently use the booster action of power equipment, the efficiency of sample treatment
It is relatively low, large area, multi-court position, more water layers field investigation in, since sample size is larger, manual press filtration mode tends not to
It is competent；In addition, for certain particulate matters or the higher water body of colloidal content, manual press filtration is also more difficult.This processing mode
It is commonly available to the occasion that accuracy of detection is more demanding and sample size is little.
In conclusion the preparation for filtrate sample, existing multi-joint suction filtration method more efficiently but easily leads to sample dirt
Dye, and the manual filter-pressing method of disposable aspiration needle filter can effectively avoid pollution but processing procedure is less efficient.Currently, still lacking one
Kind while the filtrate sample preparation method or device for meeting the requirement of efficient and low stain risk.
