Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and particularly relates to an ion chromatograph. Background Art

[0002] Ion chromatography is a kind of high performance liquid chromatography. The main difference between it and the traditional ion exchange column chromatography is that the resin has a very high cross-linking degree and a low exchange capacity. Ion chromatographs have emerged on the market and usually come with an automatic sampler for the convenience of users to conduct batch detections. However, most of the sample trays on the automatic samplers cannot be removed and replaced. After the detection is completed, the sample bottles on the sample tray have to be removed one by one before new sample bottles can be replaced, which greatly affects the work efficiency and is not conducive to batch detection.

[0005] Further improvement: The disassembly device includes: a positioning column arranged on the turntable, a positioning hole arranged on the sample tray for matching with the positioning column, and a clamping device arranged between the turntable and the sample tray for fixing the sample tray.

[0006] Further improvement: The clamping device includes: a clamping column arranged on the turntable, a clamping hole arranged on the sample tray for the clamping column to pass through, and two clamping pieces arranged on the clamping column through an elastic reset device for limiting the sample tray.

[0007] Further improvement: The elastic reset device includes: a clamping channel penetratingly opened on the clamping column, the clamping pieces are hinged to the clamping column and located at both ends of the clamping channel, and a reset device is arranged between the clamping pieces.

[0008] Further improvement: The reset device includes: mounting columns respectively arranged on the two clamping pieces and located on the opposite sides, a spring sleeved on the two mounting columns, and one end of the spring is fixedly connected to the mounting column and the other end is fixedly connected to the other mounting column.

[0009] Further improvement: A support device for enhancing the smoothness of rotation is further arranged between the sample tray and the turntable.

[0010] Further improvements are as follows: The support device includes at least three support columns evenly arranged on the turntable, a connecting column arranged on the support columns, and a connecting hole opened at the bottom of the lofting plate for the connecting column to be inserted.

[0012] Further improvements are as follows: A handle for facilitating the taking of the lofting plate is also arranged on the lofting plate.

[0013] Further improvements are as follows: A signboard is also arranged on the lofting plate.

[0014] The advantages and beneficial effects of the present utility model are as follows:

[0015] The structure is simple and the use is convenient. The lofting plate is arranged on the turntable of the automatic sampler main body through the disassembly device, so that the user can load the samples to be detected on other lofting plates when the automatic sampler is working. When the samples on another lofting plate are detected, a new lofting plate can be quickly replaced, greatly improving the connection speed during batch detection and enhancing the work efficiency.

Detailed Embodiments

[0021] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0022] AsFigures 1-4 As shown in the figure, an ion chromatograph includes an ion chromatograph main body 1 and an automatic sampler connected to the ion chromatograph main body 1. The automatic sampler includes: an automatic sampler main body 2 and a turntable 3 rotatably arranged on the automatic sampler main body 2. A sample placing plate 4 is connected to the turntable 3 through a disassembly device.

[0023] In order to enable the sample placing plate 4 to be installed on the turntable 3 at the correct angle, the disassembly device includes: a positioning post 5 arranged on the turntable 3, a positioning hole 6 arranged on the sample placing plate 4 for matching with the positioning post 5, and a clamping device arranged between the turntable 3 and the sample placing plate 4 for fixing the sample placing plate 4.

[0024] In order to enhance the connection stability between the sample placing plate 4 and the turntable 3, the clamping device includes: a clamping post 7 arranged on the turntable 3, a clamping hole 8 arranged on the sample placing plate 4 for the clamping post 7 to pass through, and two clamping pieces 9 arranged on the clamping post 7 through an elastic reset device for limiting the sample placing plate 4.

[0025] In order to facilitate the installation and disassembly of the sample placing plate 4, the elastic reset device includes: a clamping channel 10 penetratingly opened on the clamping post 7. The clamping piece 9 is hinged to the clamping post 7 and located at both ends of the clamping channel 10. A reset device is arranged between the clamping piece 9 and the clamping piece 9. The reset device includes: mounting posts 11 respectively arranged on the two clamping pieces 9 and located on the opposite sides, and a spring 12 sleeved on the two mounting posts 11. One end of the spring 12 is fixedly connected to the mounting post 11 and the other end is fixedly connected to the other mounting post 11.

[0026] In order to enhance the rotational stability of the sample placing plate 4, a support device for enhancing the rotational smoothness is further arranged between the sample placing plate 4 and the turntable 3. The support device includes: at least three support posts 13 evenly arranged on the turntable 3, a connecting post 14 arranged on the support post 13, and a connecting hole 15 opened at the bottom of the sample placing plate 4 for the connecting post 14 to be inserted into.

[0027] In order to enhance the placement stability of the sample placing plate 4, a friction gasket (not shown in the figure) is further arranged at the bottom of the sample placing plate 4, and anti-slip lines (not shown in the figure) are also opened at the bottom of the friction gasket.

[0028] In order to facilitate the handling of the sample placing plate 4, a handle 16 for facilitating the taking of the sample placing plate 4 is further arranged on the sample placing plate 4. The handle 16 is located on the side opposite to the clamping device, so that it is convenient for the user to release the clamping with one hand and pick up the sample placing plate 4 with the other hand.

[0029] In order to facilitate the distinction of each sample placing plate 4, an identification plate 17 is further arranged on the sample placing plate 4.

[0030] Working principle: When in use, first install the reagent bottle to be detected on the lofting tray 4. Then, pick up the lofting tray 4 through the handle 16, align the positioning post 5 with the positioning hole 6, so as to install the lofting tray 4. During installation, the engaging hole 8 on the lofting tray 4 resists against the engaging piece 9, thereby pushing the engaging piece 9 to move in the direction of the engaging channel 10, avoiding space for the movement of the lofting tray 4. When the movement reaches the point where the lofting tray 4 resists against the support column 13, the engaging piece 9 is located outside the engaging hole 8. At this time, the engaging piece 9 expands under the action of the spring 12, so as to realize the limit of the lofting tray 4 and complete the installation of the lofting tray 4. When disassembling, the user grabs the handle 16 with one hand and pinches the engaging piece 9 with the other hand to make it move towards the engaging channel 10, then the limit can be released, and at this time the lofting tray 4 can be taken out.
