Description
Technical field
The utility model relates to a kind of high-temperature stage of laser Raman spectroscopy, belongs to the optical experiment instrument field.
Background technology
At present, at the real-time detection range of high temperature Raman, it is very general that high-temperature stage is used in Raman spectrum.High-temperature stage can be heated to different temperature to sample, by the spectrogram of Raman spectrum test sample under different temperatures, makes people can obtain the molecular structure information of sample under different temperatures.High-temperature stage structure such as Fig. 1 of laser Raman spectroscopy, shown in Figure 2, comprise stage body 1, platform lid 2, the first quartzy cover plate 3, alumina crucible 4, aluminium oxide cover plate 5, platinum heating wire 6, circulation 7, in the middle of the platform lid 2 through hole is arranged, through-hole diameter is 10～30mm, stage body 1 is threaded with platform lid 2, stage body 1 and the platform lid 2 middle first quartzy cover plates 3 that are embedded with, alumina crucible 4 places stage body 1 inside, alumina crucible 4 top end covers have alumina cover sheet 5, it is the through hole of 2mm that there is diameter at aluminium oxide cover plate 5 centers, sample places in the alumina crucible 4, and makes alumina crucible 4 centers, the through hole center of aluminium oxide cover plate 5, the first quartzy cover plate, 3 centers keep point-blank.Platinum heating wire 6 is wrapped in the alumina crucible 4, and platinum heating wire 6 connects the intensification temperature-controlling system by lead.For making alumina crucible 4 inside that good heat-insulating property be arranged, high-temperature stage all adopts double-layer seal, earlier with 5 pairs of alumina crucible sealings of the aluminium oxide cover plate that has through hole, again with 1 sealing of 3 pairs of stage bodies of the first quartzy cover plate, stage body 1 and Tai Gai 2 are two layers of housing, two layers of enclosure interior have recirculating cooling water system 7, are used to cool off stage body 1 and Tai Gai 2, and stage body 1 inwall and first quartzy cover plate 3 inner wall temperatures will be lower than the alumina crucible internal temperature.During test sample, laser focuses on the sample by the through hole at the first quartzy cover plate 3 and aluminium oxide cover plate 5 centers.The first quartzy cover plate 3 is transparency materials, can not hinder the focusing of laser facula, does not therefore have through hole on the first quartzy cover plate 3.
The high-temperature stage shortcoming of this laser Raman spectroscopy is: if detected sample at high temperature has volatile matter to produce, volatile matter can enter in stage body 1 chamber by the through hole of aluminium oxide cover plate 3, because the temperature of the first quartzy cover plate 3 is lower than alumina crucible 4 internal temperatures, volatile matter runs into the first low quartzy cover plate 3 of temperature and will crystallization take place and bond on the first quartzy cover plate 3.When crystal was too much, the crystal on the first quartzy cover plate 3 will hinder the focusing of laser facula, thereby made the spectrogram of laser Raman spectroscopy detection less than sample, also can't detect the spectrogram of sample at higher temperature.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-temperature stage of laser Raman spectroscopy, this device can make laser Raman spectroscopy detect the sample that has volatile ingredient under the high temperature, prevent to focus on, make laser Raman spectroscopy can't detect the spectrogram of sample at higher temperature because of volatile matter crystallization on the first quartzy cover plate hinders laser facula.
For achieving the above object, the high-temperature stage of a kind of laser Raman spectroscopy described in the utility model, comprise stage body, the platform lid, the first quartzy cover plate, alumina crucible, the aluminium oxide cover plate, the platinum heating wire, circulation, in the middle of the platform lid through hole is arranged, through-hole diameter is 10～30mm, stage body is threaded with Tai Gai, be embedded with the first quartzy cover plate in the middle of stage body and the platform lid, alumina crucible places stage body inside, the alumina crucible top end cover has the alumina cover sheet, the platinum heating wire is wrapped in the alumina crucible, the platinum heating wire connects the intensification temperature-controlling system by lead, stage body and Tai Gai are two layers of housing, and in the middle of the housing recirculating cooling water system, stage body and Tai Gai being arranged all is two layers of housing, all be connected with recirculated cooling water in the middle of the housing, the utility model also comprises the second quartzy cover plate, opens a through hole at the first quartzy cover plate center, the through hole upper ends second quartzy cover plate.
The described first quartzy cover plate through-hole diameter is 3～5mm.
The described second quartzy cover plate diameter is 6～8mm.
The beneficial effects of the utility model are, by the appropriate reconstruction to the first quartzy cover plate, and add a cover the second quartzy cover plate on quartzy cover plate, and when having realized under the high temperature material with volatile component detected, laser facula can focus on the sample.

Embodiment
Below in conjunction with embodiment the utility model is further described.
As Fig. 3, shown in Figure 4, a kind of high-temperature stage of laser Raman spectroscopy, comprise stage body 1, platform lid 2, the first quartzy cover plate 3, alumina crucible 4, aluminium oxide cover plate 5, platinum heating wire 6, circulation 7, in the middle of the platform lid 2 through hole is arranged, through-hole diameter is 20mm, stage body 1 is threaded with platform lid 2, stage body 1 and the platform lid 2 middle first quartzy cover plates 3 that are embedded with, alumina crucible 4 places stage body 1 inside, alumina crucible 4 top end covers have alumina cover sheet 5, platinum heating wire 6 is wrapped in the alumina crucible 4, platinum heating wire 6 connects the intensification temperature-controlling system by lead, stage body 1 and Tai Gai 2 are two layers of housing, all have recirculating cooling water system 7, the utility model also to comprise the second quartzy cover plate 8 in the middle of the housing, the second quartzy cover plate diameter is 7mm, open a through hole at the first quartzy cover plate, 3 centers, the first quartzy cover plate through-hole diameter is 4mm, the through hole upper ends second quartzy cover plate 8.
When Raman spectrum detected, sample had been heated to volatile matter when occurring by platinum heating wire 6, and volatile matter enters in stage body 1 chamber by the through hole at aluminium oxide cover plate 5 centers, and volatile matter runs into the second low quartzy cover plate 8 of temperature, and crystallizations can take place.Along with volatile matter constantly overflows from the through hole of aluminium oxide cover plate 5, the volatile matter of the quartzy cover plate 8 of crystallization to the second is more and more, and laser facula can't focus on sample.At this moment, take off the second quartzy cover plate 8, the second quartzy cover plate 8 of a cleaning is put in the through hole upper end of the first quartzy cover plate 3, laser Raman spectroscopy is in time measured sample.If have on the quartzy cover plate 8 of volatile matter crystallization to the second of some again, and when making laser facula focus on sample, take same substitute mode, change the second quartzy cover plate 8 so repeatedly.The clear size of opening of the first quartzy cover plate 3 is compared with stage body 1, the clear size of opening of the first quartzy cover plate 3 is less relatively, have the part cold air when changing the second quartzy cover plate 8 and enter, the air capacity that enters is less, therefore can not produce big influence to stage body 1 inside and alumina crucible 5 internal temperatures.
