Abstract
The utility model relates to an analysis and detecting instrument, and discloses a novel thermogravimetric specimen bracket used for thermogravimetric analysis instrument. The novel thermogravimetric specimen bracket comprises a sensor (1), a lifting switch (7), a bracket rod (2) and a specimen platform (4), wherein the sensor is positioned under the bracket rod; the lifting switch is connected with the bracket rod; the specimen platform is in a circular disc shape, and the bottom of the specimen platform is connected with the upper end of the bracket rod; and the upper end of the edge of the specimen platform is provided with a barrier wall (6) or two or six barrier sheets (5). The utility model improves the structure of the specimen platform, so a crucible can be stably placed, the specimen scattering caused by the turnover of the crucible in the lifting process does not occur, the operation is safe and convenient, and the test results are reliable.
Description
Technical field
The utility model relates to analysis and detecting instrument, in particular for the thermal weight loss sample holder of thermal gravimetric analyzer.
Background technology
Thermal gravimetric analyzer (TGA) is a kind of important analytical instrument, can be used for detecting various materials, is widely used in research fields such as macromolecule, organic chemistry, medicine food and cosmetics.Sample is put into crucible, again crucible is placed on the thermal weight loss sample holder, put into thermal gravimetric analyzer; The thermal weight loss sample holder is put on the balance of thermal analyzer and weighs, thereby detects.
At present, the thermal weight loss sample holder of laboratory use mainly comprises cradling piece, sensor, lifting button and example platform.Cradling piece is telescopic, is controlled by direction switch.Existing thermal gravimetric analyzer, its example platform is a tripod, the crucible that will fill sample in the use is placed on the example platform of tripod, starts lifting button, can detect.
The thermal weight loss sample holder of said structure exists obvious defects, example platform is a tripod, lifting along with sample holder, the crucible that fills sample that is placed on the example platform is easy to crooked overturning, cause the sample in the crucible to be fallen on the following balance, this can bring certain influence to test result.
Therefore, need improve to overcome above-mentioned defective existing thermal weight loss sample holder.
The utility model content
The utility model aims to provide a kind of novel thermal weight loss sample holder that is used for thermal gravimetric analyzer.
Its technical scheme is: a kind of novel thermal weight loss sample holder, comprise sensor, direction switch, cradling piece and example platform, and sensor is positioned at the cradling piece below, and direction switch is connected with cradling piece; Example platform is discoid, and its bottom is connected with the upper end of cradling piece.
Optimized technical scheme is that the upper end, edge of example platform is provided with two to six barrier sheets.More preferably, each barrier sheet evenly distributes at the edge of example platform.
Another optimized technical scheme is, the upper end, edge of example platform is provided with barrier, and barrier be an annular, and its size is mated with example platform.
The material of example platform and barrier sheet, barrier can be selected aluminium oxide or platinum for use.
Because example platform is discoid, makes the placement of crucible more steady.Barrier sheet or barrier can also play a protective role, and prevent that crucible from influencing test because of skew taking place or tilting with sample is unrestrained to following balance.
Of the present utility model simple in structure, only need reequip existing thermal weight loss sample holder; Easy-to-operate makes test process more reliable.

Embodiment
The comparative example
As shown in Figure 1, existing thermal weight loss sample holder comprises sensor 1, cradling piece 2, tripod example platform 3 and direction switch 7.Cradling piece is telescopic, is controlled by direction switch.Sensor is positioned at the cradling piece below, and direction switch is connected with cradling piece; The bottom of tripod example platform is connected with the upper end of cradling piece.
The crucible that fills sample is placed on the tripod example platform, presses direction switch, and cradling piece can stretch, the position of control crucible.Because crucible bottom can not contact fully with the tripod example platform, in the process of moving up and down, place shakiness easily, cause the interior sample of crucible to drop, thereby influence test findings.
As shown in Figure 2, the structure of novel thermal weight loss sample holder comprises sensor 1, cradling piece 2, example platform 4 and direction switch 7, and sensor is positioned at the cradling piece below, and direction switch is connected with cradling piece; Example platform is discoid, and its bottom is connected with the upper end of cradling piece.Be with comparative example's difference, the tripod example platform is replaced with example platform with the disc-shape of diameter.
The upper end, edge of example platform is provided with three barrier sheets 5, and each barrier sheet size is identical with shape, and each barrier sheet evenly distributes on the edge of example platform.The material of example platform and barrier sheet is a platinum.
In the operating process, earlier novel thermal weight loss sample holder is installed in the thermal gravimetric analyzer, crucible is put on the example platform again, press direction switch, setting program carries out weightless test then.
This novel thermal weight loss sample holder; improved the structure of example platform; because example platform is discoid; make the placement of crucible more firm; and barrier sheet can also play a protective role; prevent that crucible from causing sample to be scattered because of tipping in lifting process, easy-to-operate, test result is more reliable.
As shown in Figure 3, the structure of novel thermal weight loss sample holder comprises sensor 1, cradling piece 2, example platform 4 and direction switch 7, and sensor is positioned at the cradling piece below, and direction switch is connected with cradling piece; Example platform is discoid, and its bottom is connected with the upper end of cradling piece.Be with comparative example's difference, the tripod example platform is replaced with example platform with the disc-shape of diameter.
The upper end, edge of example platform is provided with barrier 6, and barrier is the thin slice of annular, and its size and example platform are complementary.The material of example platform and barrier is an aluminium oxide.It uses and operates with embodiment 1.Discoidal example platform and stop that wall energy makes the placement of crucible more firm prevents that crucible from causing sample to be scattered because of tipping in lifting process, easy-to-operate, and test result is more reliable.
