Description
Technical field
This utility model is related to a kind of half In situ XPS sample transfer device, belongs to x-ray photoelectron power spectrum (XPS) technology
Field.
Background technology
The conventional input mode of photoelectron spectrograph be first by sample preparation in standard sample support, be then transferred to instrument
Sample Room carry out forvacuum, sample is all an exposure under atmospheric environment in this course, compares for some surfaces
Sensitive (as oxidizable, easy deliquescence) or the XPS test result of harsher particular sample (as UPS sample) is required to affect very
Greatly, it is exposed in atmospheric environment even if this kind of sample is of short duration, its surface also can be reacted with air (oxygen gas and water etc.) quickly,
Produce new chemical substance, increased complexity and the uncertainty of spectrum elucidation.
Content of the invention
For the problems referred to above, the purpose of this utility model is to provide one kind to make sample be accomplished to entrance power spectrum instrument from preparation
During avoid the half In situ XPS sample transfer device that contacted with air.
For achieving the above object, this utility model employs the following technical solutions：A kind of half In situ XPS sample transfer device,
It is characterized in that：Including sample carrier and sample cover, the top of described sample carrier is provided with circular orientation boss, in described sample
The bottom of cover is provided with circular draw-in groove, and described sample cover buckles on described sample carrier and described circle draw-in groove is fixed with described annular
Position boss engaging, is provided with sealing ring between described circle draw-in groove and described circular orientation boss, sets on described sample cover
It is equipped with vacuum-pumping tube, described vacuum-pumping tube is provided with vacuum plug valve.
It is provided with the pulling part with through hole at the top of described sample cover.
Due to taking above technical scheme, it has advantages below to this utility model：This utility model can make sample from
Preparation be accomplished to enter power spectrum instrument whole process refuse air ambient contacted, thus ensureing the effectiveness of measurement data
And accuracy.
Brief description
Fig. 1 is external structure schematic diagram of the present utility model；
Fig. 2 is cutting structural representation of the present utility model；
Fig. 3 is the XPS spectrum figure of Li1s in Li battery sample；
Fig. 4 is the XPS spectrum figure of O1s in Li battery sample.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of half In situ XPS sample transfer device, including sample carrier 1 He
Sample cover 2, is provided with circular orientation boss 3 at the top of sample carrier 1, and the bottom of sample cover 2 is provided with circular draw-in groove, sample
Cover 2 buckles on sample carrier 1 and circular draw-in groove is engaged with circular orientation boss 3.Between circular draw-in groove and circular orientation boss 3
It is provided with sealing ring 4.Vacuum-pumping tube 5 is provided with sample cover 2, (in figure is not to be provided with vacuum plug valve in vacuum-pumping tube 5
Illustrate).
In a preferred embodiment, the top in sample cover 2 is provided with pulling part 6, is provided with logical on pulling part 6
Hole 7.
Use process of the present utility model is as follows：
1) in glove box (being inert gas environment in glove box), sample 8 is prepared on sample carrier 1, specifically by sample
8 are placed in circular orientation boss 3.
2) in glove box, sample cover 2 is buckled on sample carrier 1, and make circular draw-in groove and the ring of sample cover 2 bottom
Shape positioning boss 3 engages.
3) using fixed mount, sample cover 2 is fixed with sample carrier 1, close between sample cover 2 and sample carrier 1 to ensure
Envelope.
4) vacuum-pumping tube 5 is connected with the pipeline of vacuum air distribution system, by the chamber vacuum pumping state in sample cover 2
(pressure is about 5Pa), close vacuum plug valve afterwards.
5) take off fixed mount, then this utility model device is sent into the Sample Room forvacuum of photoelectron spectrograph, treat
After inside and outside sample cover 2, pressure reaches balance, sample cover 2 will automatically disengage sample carrier 1, and the sample parking platform using Sample Room is extractd
Sample cover 2 (can be extractd by lifting pulling part 6).
6) sample 8 is sent into analysis room.
Whole process achieves sample and does not contact atmospheric environment in transfer process.
Of the present utility model technique effect is exemplified below：
Fig. 3 and Fig. 4 is that Li battery sample adopts this utility model device and conventional standard sample support two ways sample introduction
The XPS spectrum figure contrast recording, concretely comprises the following steps two same samples of preparation, is respectively adopted this utility model device and routine
Standard sample support sample introduction simultaneously carries out XPS test.The a of in figure represents this utility model device sample introduction, and b represents using conventional standard
Sample carrier sample introduction.From the point of view of test result, using the sample of conventional standard sample support sample introduction, due to sample in transfer process not
Atmospheric environment can be avoided contact with, even if open-assembly time is extremely short, its surface also can be reacted with air (oxygen gas and water etc.) quickly,
Produce new chemical substance, increased complexity and the uncertainty of spectrum elucidation.And adopt half In situ XPS sample transfer device
After protection sample introduction, sample in whole transfer process not in contact with atmospheric environment, the surface-element message reflection therefore recording be
More really close to the sample surfaces state of original position.
This utility model is only illustrated with above-described embodiment, and the structure of each part, set location and its connection are all can
Be varied from.On the basis of technical solutions of the utility model, all according to utility model principle of the present utility model to individual
Improvement or equivalents that other part is carried out, all should not exclude outside protection domain of the present utility model.
