Detailed description of the invention
Below, composition graphs 1 is described in detail to technical scheme provided by the utility model:
The utility model provides a kind of SPE auxiliary piping system being applicable to large volume Liquid sample introduction.Pipe-line system is made up of (Fig. 1) the puncturing head 31 connected successively from top to bottom, air cleaner 33, stream controller 35, liquid line 36, fluid collection tube 37, flow regulator 38, liquid filter 39 and SPE pillar 310.
Puncturing head is rigid plastics puncturing head, and puncturing head outside is set with by protective sleeve 32, the flow regulator 38 between fluid collection tube 37 and liquid filter 39.
Air cleaner 33 keeps certain atmospheric pressure in sample bottle for ensureing in sample introduction process, and the liquid in such sample bottle could rely on Action of Gravity Field constantly to flow in pipe-line system at atmosheric pressure.Meanwhile, in order to ensure that the air entered in sample bottle is clean, air filtration 34 being also installed on the top of air cleaner, to remove the pollutant in air, avoiding air to the pollution of sample.
See Fig. 2, the liquid filter 39 that the utility model adopts is made up of the steam vent 391 on it, filter membrane 392, sieve plate 393 and housing 394.
The utility model in use, two puncturing heads 31 are connected on the top that upper end is the teflon hose of the twin adapter of V-type respectively, select the puncturing head 31 of one end to puncture to be inverted in the utility model provide the aluminum bottle cover wrapped up outside the sample bottle of auxiliary piping system head to make puncturing head 31 penetrate the fluorubber plug of the sample bottle bottle cap of upside down, now open the stream controller of this end, adjust flux adjuster 38 just can control the flow rate of liquid of the influent filter 39 flowed out from v-shaped tube one end like a cork simultaneously, allow pending fluid sample flow through liquid line with uniform speed and finally flow in SPE pillar 310 to reach the object of the target compound of trace in extraction and concentration fluid sample.
The utility model in use, fluid sample from up to down flows out from one end of v-shaped tube and flows to collection fluid collection tube 37 along pipeline from top to down, when the fluid pressure in fluid collection tube is greater than atmospheric pressure, the liquid in sample bottle will flow in liquid filter 39 along flexible pipe from top to down.Filter membrane 392 in liquid filter 39 can carry out pre-filtering to the solid content be present in fluid sample, and the larger solid content of particle in fluid sample is filtered, and prevents its blocking SPE pillar 310.Meanwhile, in order to prevent the filter membrane 392 in liquid filter 39 from being blocked completely by the solid content in fluid sample, liquid filter 39 is herein designed to detachable.After filter membrane 392 in liquid filter is completely plugged, filter membrane 392 can be disassembled, change new filter membrane and proceed solid phase extraction manipulations, and do not lose sample or affect experimental result.
Just no longer enter in this pipe-line system by the liquid of closing in the stream controller Quality control bottle of this one end after the fluid sample sample introduction in a sample injection bottle is complete, and now can by regulating the pipe-line system of this end of stream controller opens of the V-arrangement pipe other end, the liquid in this end sample bottle just can enter pipe-line system and finally enter in SPE pillar 310 and carry out separation and concentration.
The upper end that pipe-line system except rigid plastics puncturing head 31, rigid plastics fluid collection tube 37 and liquid filter 39 is all made up of teflon hose is the twin adapter pipe-line system of V-arrangement.
