Abstract
The utility model discloses tubing string that is a kind of and mass spectrometry, it comprises analyzes column jecket and spraying column jecket, and described analysis column jecket is one-body molded with spraying column jecket, and described analysis column jecket is circular tube shaped, and described spraying column jecket is conical tubular.The utility model is one-body molded with spraying column jecket by analyzing column jecket, achieves and does not need chromatograph or electrophoresis apparatus and mass spectrographic interface that sample to be analyzed can be made directly to enter mass spectrometer analysis from chromatograph or electrophoresis apparatus, easy to operate, saves artificial.
Description
Technical field
The utility model belongs to technical field of chromatographic analysis, is specifically related to tubing string that is a kind of and mass spectrometry.
Background technology
Liquid chromatography and mass spectrometric hyphenated technique are developed rapidly and widespread use at chromatographic resolution analysis field.Along with life science, environmental science, the developing rapidly of biomedicine field, higher demand is proposed to this technology.Especially the separation for precious sample detects, and requires less sample size.So Nano liquid chromatography, Capillary Electrophoresis, capillary electric chromatogram and mass spectrometric hyphenated technique obtain the favor of numerous clients.Wherein, liquid chromatograph, capillary electrophoresis apparatus, capillary electric chromatogram instrument and mass spectrographic interfacing are vital, and comprise driving-belt interface, directly fluidic interface, thermospray interface, electrospray interface, electrospray ionization mass spectrum application is very extensive.In electrospray ionization mass spectrum, chromatographic chromatographic column is led to by one two and is connected with mass spectrometer interface, and such sample enters Mass Spectrometer Method after being separated by chromatograph.Operationally some is complicated on the one hand, and require very high to interconnection technique on the other hand, the connection parts of needs are more, assemble also more complicated.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide one does not need interface that sample to be analyzed just can be allowed directly to enter mass spectrometer analysis, and device simple to operate.
For achieving the above object, the utility model have employed following technical scheme:
With a tubing string for mass spectrometry, it comprises analyzes column jecket and spraying column jecket, and described analysis column jecket is one-body molded with spraying column jecket, and described analysis column jecket is circular tube shaped, and described spraying column jecket is conical tubular.
As the further optimization of such scheme, described spraying column jecket is nozzle needle, and the port inner diameter of this nozzle needle is less than 30 microns.
Further, the internal diameter of described analysis column jecket is 50 ~ 300 microns.
Further, described analysis column jecket is open tubular column, as the capillary column of capillary electrophoresis apparatus; Or described analysis column jecket is packed column, can be used as the liquid-phase chromatographic column of Nano phase chromatography-use or the chromatographic column of capillary electric chromatogram.
Further, described analysis column jecket adopts fused quartz or stainless steel to make.
Compared with prior art, the beneficial effects of the utility model main manifestations is: the utility model by by analysiss hold and spraying end one-body molded, achieve and do not need interface that sample to be analyzed can be made directly to enter mass spectrometer analysis, easy to operate, save artificial.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is more specifically described.
Embodiment 1
As shown in Figure 1, a kind of tubing string with mass spectrometry, it comprises analyzes column jecket 1 and spraying column jecket, described analysis column jecket 1 and spraying column jecket one-body molded, described analysis column jecket 1 is circular tube shaped, and described spraying column jecket 1 is conical tubular.Described spraying column jecket is nozzle needle 2, and port 3 internal diameter of this nozzle needle 2 is 10 microns.The internal diameter of described analysis column jecket 1 is 100 microns.Described analysis column jecket 1 is packed column, and it is built with filler 4, can be used as the liquid-phase chromatographic column of Nano phase chromatography-use or the chromatographic column of capillary electric chromatogram.Described analysis column jecket 1 adopts fused quartz or stainless steel to make.
The present embodiment, when applying, will be analyzed column jecket 1 and be connected with sample to be analyzed, the filler 4 under stress by analysis in tubing string 1, and then arrival nozzle needle 2 sprays, and does not have unnecessary link, operate and structure all very easy, saving is manually and resource.
Embodiment 2
As shown in Figure 2, compared with embodiment 1, difference is, analyzing column jecket 1 is open tubular column, does not have filler, can be used as the capillary column of capillary electrophoresis apparatus in it.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, deduce other unitized construction, and all these be changed or replace the protection domain that all should belong to the utility model claim.
