Description
Technical field
This utility model is related to liquid ingredient analysis technical field, more particularly, to a kind of extraction module and liquid preprocessing
Device.
Background technology
Processing mode before the detection of traditional liquid sample generally has sampling, sample preparation, weighing, liquid liquid distribution extraction
Take, solid extracting agent purification, sample filtering, sample transfer etc. step.These steps are all independent step-by-step operations at present：Example
Such as, after liquid sample sampling, sample preparation, weighing step are completed, a single utensil and step is needed to carry out liquid liquid point
With extraction, then change another utensil into or the step of equipment carries out Solid phase extraction, subsequently need using in addition
Equipment and utensil the step of carry out sample filtering, final sample transfer is also the same.
Wherein, current liquid liquid distribution extraction needs special liquid liquid distribution vial, by water and immiscible with water
Then solvent concussion, standing, layering release lower floor by valve, complete assigning process；Also to have been reported that liquid is carried out using kieselguhr
Liquid distributes.The shortcoming of above two method is all to need to complete using single utensil, can not be merged together with the step of other
Shi Jinhang, needs to expend substantial amounts of organic solvent, and the subsequent step that typically will also have concentrating under reduced pressure can just be completed.

Fusion is completed together.Or the pipe of syringe shape is not used, solid extracting agent is applied directly to into fluid sample to be measured directly
Interior, suck up impurity, but a disadvantage is that after effect of extracting is undesirable, and extraction step is completed, also have to have a filtration
Or solid extracting agent is separated with the sample after purification the step of centrifugation.
Current sample filtering step is that the liquid of testing sample is transferred to syringe or similar using special utensil
In the pipe of type effect, the sample in pressure injector is promoted using piston rod, make sample through the filter for being installed to syringe bottom
Film, reaches the purpose of filtration.Finally again the sample for having filtered is transferred in corresponding vial.
The pre-treatment of current liquid sample all steps (liquid-liquid extraction, Solid phase extraction, sample filtering,
Sample is shifted) all separately complete, step is cumbersome, and easily pollutes during filtering, purifying and shifting molten
Agent, so that have that testing result is inaccurate；And step is more, need the special implement for using also many, and structure
Complexity, so that the amount of the organic solvent for consuming is also more, the stability, accuracy to testing result, and the discharge of nuisance
Also it is bigger.
