Description
Technical field
The invention patent relates to a kind of experimental apparatus, and in particular to a kind of solid-phase extraction column series connection holder.
Background technology
Solid Phase Extraction (Solid Phase Extraction, abbreviation SPE) is a kind of common in trace species analysis
Pretreatment technology.It is in the actual use process it is generally necessary to different using two or more according to the complexity of sample substrate
Solid-phase extraction column the case where being used in series of adsorbent type, different adsorption mechanism.
Currently, main solid-phase extraction device manufacturer can generally provide series connection solid-phase extraction column for client both at home and abroad
Adapter, but these traditional adapters are positioned over lower end Solid Phase Extraction after upper end solid-phase extraction column is only inserted into adapter
Mode on column.This mode, which has problems in that, lacks good fixation between adapter and lower end solid-phase extraction column, cause
Make to connect between upper end solid-phase extraction column and lower end solid-phase extraction column not enough securely.
Carry out Solid Phase Extraction loading, elution during operating personnel slightly slip up touch upper end solid-phase extraction column when
Will cause the rollover of the Solid Phase Extraction of upper end and topple over, wherein for SPE purification sample extraction concentrate can lose to
Pre-treatment is caused to fail.Although experimenter needs careful operation, multiple series connection solid phases during processing before progress
The case where extraction column is collided with when being carried out at the same time pre-treatment can still occur often.For this purpose, being transferred using traditional Solid Phase Extraction
Head series connection solid-phase extraction column carries out pre-treatment, and there are the larger hidden danger for leading to the failure of an experiment.
It finds, lacks in current experiment equipment to two kinds and the above Solid Phase Extraction after the retrieval and inquisition of inventor
The concatenated related equipment of column, causes the difficulties when connecting two kinds and its above solid-phase extraction column.
In order to overcome conventional solid extraction column adapter to fix series connection, SPE columns are insecure, columns in series is easy to touching rollover and leads
The shortcoming of the failure of an experiment, patent of the present invention is caused to provide a kind of solid-phase extraction column series connection holder, can preferably solve often
The problem of leading to the failure of an experiment hidden danger caused by rule solid-phase extraction column adapter.
Invention content
The technical issues of patent of the present invention, fixes series connection SPE columns loosely it is intended that solving conventional solid extraction column adapter
Gu, columns in series be easy to the deficiency that touching rollover causes the sample extraction concentrate for purification to lose, provide it is a kind of it is simple in structure,
The former phase extraction column that can be adapted with existing main specifications model is connected holder.
A kind of solid-phase extraction column series connection holder, there are two 1, two Parallel Symmetrics of symmetrical support base for the holder
Supported rod erecting 2,4, two symmetrical horizontal drawing bars 5 of flat guide rod of 3, two Parallel Symmetrics of fixed cross beam and two or so pairs
The brace 6 of title, it is characterised in that：Have can be up and down the string of solid-phase extraction column fixation kit 7 in two Parallel Symmetrics
On flat guide rod 4.
Particularly, solid-phase extraction column fixation kit 7 is parallel right by two of overhead gage 8, lower baffle plate 9 and the upper lower baffle plate of connection
The light spring 10 of title forms.
Particularly, there is through-hole 11 on perforative large aperture on overhead gage 8, while having a fixation Solid Phase Extraction in overhead gage 8
The latch notch groove 12 of column.
Particularly, there is perforative small-bore lower through-hole 13 on lower baffle plate 9.
The application method of patent of the present invention：
First the overhead gage 8 of fixation kit 7 and lower baffle plate 9 are strutted when use, solid-phase extraction column lower end fluid port is inserted into
In lower through-hole 13, upper newel post's bayonet of solid-phase extraction column is pushed into latch notch groove 12, lower baffle plate in relieving, light spring is received
It contracts and fixes solid-phase extraction column.When being connected using multiple solid-phase extraction columns, different solid-phase extraction columns can be installed to difference
Fixation kit in, under gravity, each fixation kit for installing solid-phase extraction column is slided and is combined at one, complete
The series connection of Cheng Duogen solid-phase extraction columns.
The advantages of patent of the present invention, is：
1. patent of the present invention is compared with solid-phase extraction column adapter, patent of the present invention can easily install two kinds and with
On solid-phase extraction column, series connection is secured, can effectively prevent using conventional solid extraction adapter connect solid-phase extraction column when be easy to
It falls and liquid to be clean is caused to lose in touching side.
2. the structure of patent of the present invention is simple, is extracted using the easy to operate, solid phase that can be connected according to the adjustment of the needs of pre-treatment
The characteristics of taking column quantity.
Description of the drawings
1. Fig. 1 is the schematic diagram of patent of the present invention.
2. Fig. 2 is schematic diagram of the patent of the present invention in embodiment with solid-phase extraction column series system.
Specific implementation mode
Further to disclose rather than patent of the present invention is limited, patent of the present invention is made below in conjunction with example further detailed
It describes in detail bright.
Embodiment
The application method of patent of the present invention and obtainable is shown in the present embodiment by taking three solid-phase extraction columns of connecting as an example
Technique effect.
A kind of solid-phase extraction column as shown in Figure 2 is connected holder, first by the overhead gage 8 and lower block of fixation kit 7 when use
Plate 9 struts, and solid-phase extraction column lower end fluid port is inserted into lower through-hole 13, upper newel post's bayonet of solid-phase extraction column is pushed into card
In port recess 12, lower baffle plate in relieving, light spring shrinks and fixes solid-phase extraction column, completes a fixation kit and fixes one
The process of root solid-phase extraction column；
Two solid-phase extraction columns separately are taken, are fixed respectively according to the method described above successively, then by mounted three groups of fixation groups
Part and solid-phase extraction column slide downward and under gravity each fixation kit combination for installing solid-phase extraction column are one
Place completes the series connection of three solid-phase extraction columns.
The embodiment of patent of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for a person skilled in the art,
Under the premise of not departing from inventional idea of the present invention, various modifications and improvements can be made, these belong to the guarantor of the present invention
Range is protected, therefore the protection domain of patent of the present invention should be determined by the appended claims.
