Background technology
It is net that Solid Phase Extraction as a kind of Sample Pretreatment Technique, using the physical extraction process of liquid phase and solid phase reaches sample
The purpose of change, and mostly use the solid-phase extraction column of commercialization.Since SPE columns are smaller and should not fix, conditional laboratory
The automatic solid-phase extractor device of commercialization is mostly used to complete sample purification, but instrument and equipment is of high cost, a sample per treatment,
Speed is slower；Laboratory without automatic solid-phase extractor can only be manually operated, can be with the multiple samples of single treatment, but not have
Fixing device brings very big inconvenience to SPE purification process well.To make SPE purify sample, the operation is more convenient, needle
SPE columns common to laboratory, volumetric flask and sample bottle feature, can provide it is a disclosure satisfy that SPE elution, sample purification,
The Solid Phase Extraction holder of the functions such as sample collection, waste collection, exactly the design original intention of the utility model.
Invention content
The purpose of this utility model is exactly to provide a kind of Solid Phase Extraction use for the shortcoming in the presence of the prior art
Holder device realizes multiple samples Solid Phase Extraction simultaneously, greatly shortens time for sample pretreatment, to improve sample pre-treatments effect
Rate.The holder is constituted by three layers, and upper layer is SPE column fixed beds, and middle layer is fixed sample bottle or specimen cup or volumetric flask, lower layer
For waste collection layer, which can make sample handling processes, and the operation is more convenient, and greatly improves sample pre-treatments efficiency.
The purpose of this utility model is achieved through the following technical solutions：A kind of Solid Phase Extraction holder device, should
Device is constituted by three layers, and wherein top layer is solid-phase extraction column fixed bed, including top layer laminate and is opened in multiple on the laminate
（6-10）Circular socket holes for inserting solid-phase extraction column；Middle layer is sample reception layer, including mesosphere board and is opened in this
The semicircle jack for placing sample bottle at laminate edge, and fifty-fifty circular socket holes are corresponded with the circular socket holes on top layer
And with one heart；Bottom is waste collection pond, and a waste liquid flow-guiding mouth is equipped in bottom of pond.Waste liquid can be made directly to instill waste liquid pool, through conduit
Discharge.
More specifically, the Solid Phase Extraction holder device mainly has solid-phase extraction column（SPE columns）Fixed bed, sample reception
Layer, bracket base and waste liquid delivery line are constituted, and constitute an entirety.Wherein SPE columns fixed bed is for fixing SPE columns, sample
Product receiving layer can place specimen cup or volumetric flask, and semicircle jack structure makes specimen cup place, it is very convenient to take out.Holder bottom
Seat tool has waste collection and discharge function.In use, SPE columns are placed in SPE column fixed beds, and when needing to clean SPE columns, cleaning solution
It flows directly into bracket base and is introduced directly into liquid waste collector through sewer pipe；When collecting sample, specimen cup or volumetric flask are placed in
Sample reception layer, the object on SPE columns directly instill in specimen cup or volumetric flask.
The utility model is directed to the common SPE columns in laboratory, volumetric flask and sample bottle feature, devises a disclosure satisfy that
The Solid Phase Extraction holder of the functions such as SPE elution, sample purification, sample collection keeps SPE purification sample operations more square
Just, it and can realize multiple samples Solid Phase Extraction simultaneously, improve working efficiency.
Description of the drawings
Fig. 1 is the Solid Phase Extraction holder device of the utility model,
In figure：1 is fixed bed, and 1.1 be circular socket holes；2 be sample reception layer, and 2.1 be semicircle jack；3 receive for waste liquid
Ji Chi, 3.1 be waste liquid flow-guiding mouth；4 be side plate。
Specific implementation mode
The utility model is below in conjunction with attached drawing（Embodiment）It is described further：
As shown in Figure 1：A kind of Solid Phase Extraction holder device, is constituted, wherein top layer is fixed for solid-phase extraction column by three layers
Layer 1, including top layer laminate and be opened in multiple on the laminate（6-10）Circular socket holes 1.1 for inserting solid-phase extraction column；
Middle layer be sample reception layer 2, including mesosphere board and be opened in the laminate edge for place sample bottle semicircle insert
Hole 2.1, and fifty-fifty circular socket holes on top layer circular socket holes correspond and it is concentric；Bottom is waste collection pond 3, in bottom of pond
Equipped with a waste liquid flow-guiding mouth 3.1.
Application Example 1
SPE columns are positioned over to the solid-phase extraction column fixed bed of the device, the activating solution of certain volume is added in SPE columns,
After the completion of to be activated；The sample solution of certain volume is pipetted in SPE columns, waits for that solution no longer drips from the lower ends SPE, by specimen cup or
Volumetric flask places the sample reception layer with the device, the eluent of certain volume is added in SPE columns, the sample collection after elution
In specimen cup or volumetric flask, you can the analysis for object is tested.
Example 1
When continuous flow method measures the burst size of ammonia of main stream smoke of cigarette, 10 can be at least trapped by smoking machine every time
A fume sample, sample need activated carbon SPE column purifications after dilute hydrochloric acid solution extracts.10 activated carbon SPE columns are placed in this
The solid-phase extraction column fixed bed of device pipettes 5mL activated solutions on activated carbon SPE columns, and liquid stream to be activated goes out completely, pipettes
In on SPE columns, sample solution is collected in 10 mL volumetric flasks 5mL sample solutions, then add 2mL elutions after, solution collect
In 10 mL volumetric flasks；Sample is handled using 2 devices, sample pre-treatments efficiency will be greatly improved.
Example 2
When continuous flow method measures Cr VI in cigarette tipping paper, sample extraction solution generally requires to use polyamide SPE columns
Carry out sample solution purification, SPE column activation methods：The solid-phase extraction column that 10 activated carbon SPE columns are placed in the device is fixed
Layer, pipettes 5mL methanol on activated carbon SPE columns；Intact pressue device being connect with double-strand ball and being put in solid-phase extraction column consolidate
The top of given layer, sealing is intact, keeps its air tight；Then 5mL water is added, adds low pressure with double-strand ball, makes aqueous solution with a constant current
Speed outflow, when liquid level is close to the column solid-phase layer upper ends SPE, removes pressue device；Again with 5mL sample extraction solution is added, with double
Hammer adds low pressure, and aqueous solution is made to be flowed out with certain flow rate, when liquid level is close to the column solid-phase layer upper ends SPE, removes pressue device；
The activation of SPE columns is completed；Efflux flows directly into bracket base in activation process, and waste liquid pool is flowed into through conduit.At 2 devices
Sample is managed, sample pre-treatments efficiency will be greatly improved.
