Specific embodiment
In the following, being further described in conjunction with attached drawing to structure and working principle etc. of the invention.
Referring to Fig. 3~Fig. 5, chromatography column holder of the invention includes ontology 5, which is equipped with for accommodating chromatographic column 4
Accommodation groove 501, accommodation groove 501 have for chromatographic column 4 tail portion 402 stretch out opening 5011.As shown in figure 3, can be by chromatography
Column 4 is placed in accommodation groove 501 after coiling, the head 401 of chromatographic column 4 and the three-way connection 2 or four-way connection that are mentioned below
Outlet be connected, the entrance of mass spectrometer detector is then stretched out from opening 5011 and extended in the tail portion 402 of chromatographic column 4.Using this
Chromatography column holder with accommodation groove 501, no matter chromatographic column how long can all deposit in an orderly manner accommodation groove 501 after coiling
It is interior.
Since the external structure of chromatographic column 4 is the quartz capillary with toughness and hardness, toughness can make chromatography
The coiling bending of column 4, but hardness again limits the degree of the coiling bending of chromatographic column 4, therefore, as a preferred method, such as Fig. 3
Shown, accommodation groove 501 can be oval, so that chromatographic column 4 is easier to store and does not allow frangibility.
For the compactedness of structure, the cross recess for placing three-way connection 2 or four-way connection is additionally provided on ontology 5
502, as shown in figure 3, cross recess 502 is connected with accommodation groove 501, the head 401 of chromatographic column 4 be connected to three-way connection 2 or
The outlet of four-way connection.
If placing three-way connection 2 in the cross recess 502, two imports 201,202 of three-way connection 2 are separately connected from liquid phase
The DC voltage connector of the mobile phase pipeline that chromatograph extracts and ion source, outlet 203 then connect the head of chromatographic column 4
401.The working principle of the three-way connection 2 an are as follows: import of the mobile phase through three-way connection 2 to come is conveyed from liquid chromatograph
201 enter inside three-way connection 2, and DC voltage is entered inside three-way connection 2 by another import 202 of three-way connection 2, will
Compound in mobile phase and mobile phase is ionized, and the mobile phase after ionization enters chromatographic column through the outlet 203 of three-way connection 2
4。
If placing four-way connection in the cross recess 502, two imports of four-way connection, which are separately connected from liquid chromatograph, draws
The DC voltage connector of mobile phase pipeline and ion source out, the head of the one outlet connection chromatographic column 4 of the four-way connection
Portion 401, another outlet are connected by pipeline with waist valve.The working principle of the four-way connection are as follows:, should when waist valve closure
Four-way connection is identical as the working principle of above-mentioned three-way connection 2, and details are not described herein again;When waist valve is opened, from liquid chromatogram
An import of the mobile phase through four-way connection that instrument conveying comes enters inside four-way connection, and DC voltage is by the another of four-way connection
One import enters inside four-way connection, and the compound in mobile phase and mobile phase is ionized, the mobile phase after ionization
One outlet through four-way connection flows out and enters waste liquid bottle through waist valve, without entering chromatographic column 4.
Since chromatographic column 4 is chronically exposed in outside air, the barrel temperatures of chromatographic column 4 can with the change of environment temperature and
It fluctuates and Temperature Distribution is also uneven, seriously reduce the splitter effect of chromatographic column 4.As shown in Fig. 3~Fig. 5, in order to make chromatography
The barrel temperatures of column 4 are stable and are evenly distributed, and can offer the first blind hole 503 for heating rod insertion in the lower part of ontology 5, add
Hot pin can be inserted into first blind hole 503 and heat to the ontology 5, and then protect to the chromatographic column 4 being placed in accommodation groove 501
Temperature, the barrel temperatures to ensure chromatographic column 4 are stable and are evenly distributed.
It further,, can also be in ontology 5 in order to preferably control the barrel temperatures of chromatographic column 4 with continued reference to Fig. 3~Fig. 5
Lower part offer for temp probe insertion the second blind hole 504.Above-mentioned temp probe and heating rod are connected with temperature controller,
Wherein, temp probe can measure the internal temperature of ontology 5, reflect that the temperature of the chromatographic column 4 in accommodation groove 501, temperature are visited indirectly
By the temperature feedback measured to temperature controller, which opens head further according to the temperature measured control heating rod
It closes.Preferably, thermocouple can be selected in temp probe.
Ontology 5 is securable in ion source, and as an implementation, ontology 5 is securable to be previously mentioned in the prior art
Round bar 1 on, referring to Fig. 6, round bar 1 is fixed in ion source, then ontology 5 is securable on the round bar 1.
Since one end of round bar 1 in the prior art is fixed on the fixed part 3 of ion source, ontology 5 can be sheathed on circle
It on bar 1 and is fixed on fixed part 3, to guarantee the stability of the placement of ontology 5, is further ensured that chromatographic column 4 can steadily be set
In in accommodation groove 501.Specifically, referring to Fig. 6 and in conjunction with Fig. 3~Fig. 5, the lower part of ontology 5 offers the through-hole worn for round bar 1
505, while it being also provided with the trough with straight angle 506 matched with the fixed part 3 of rectangular in cross-section, the trough with straight angle 506 and 505 phase of through-hole
Connection.
The ontology 5 of chromatography column holder of the invention is equipped with the accommodation groove 501 for accommodating chromatographic column 4, different length
Chromatographic column 4 can be placed in the accommodation groove 501 after coiling, and avoided chromatographic column 4 and put unordered and be easy to be risk of damage to.Separately
Outside, the second blind hole 504 that the lower part of ontology 5 is equipped with the first blind hole 503 be inserted into for heating rod and is inserted into for temp probe, can be with
It realizes the heating to chromatographic column 4 and temperature controlling function, chromatographic column 4 isolated column effect, stability and reproducibility can not only be improved, also
It can be avoided replacement ion source, save the cost.
More than, schematic description only of the invention, it will be recognized by those skilled in the art that without departing from work of the invention
On the basis of making principle, a variety of improvement can be made to the present invention, this is all belonged to the scope of protection of the present invention.
