For this reason, a degasser is generally installed and used by piping from the ion exchange water storage tank to the degasser. As a degassing device, a device using a gas permeable film is generally used.

が起り、脱ガス効率の低下をもたらす。In the above configuration, bubbles are generated in the pipe connecting the ion-exchanged water storage tank and the degassing device due to a change in temperature, and these bubbles pass through the degassing device and enter the pump system to lower the accuracy. Cause This bubble cannot be removed by a gas permeable membrane type degasser, and a bubble must be provided to separate the bubble and the accumulated gas must be removed when the operation is stopped or discharged from time to time by a pump. In the first place, when the water from which the dissolved gas is removed comes into contact with the bubbles, the gas is redissolved and the degassing efficiency is lowered.

れば充分効果を発揮する。As described in the above section, the means for solving the problem is to prevent bubbles from entering the degassing apparatus, and it is necessary to take appropriate measures at the inlet side of the degassing apparatus. That is, it is effective to provide the bubble separation immediately before the inlet side, instead of separating the bubbles passing on the outlet side of the degasser. The proposal for the solution is simple and eliminates the piping that causes bubbles. That is, the main part of the degassing device may be immersed in the ion exchange water storage tank. Generally, a gas permeable membrane type degassing device consists of a vacuum pump, a membrane separation module and a control system, and the membrane separation part is separated and immersed so that the treated water inlet is below the water surface of the water tank. . This idea was not born from the idea of installing a degasser in a clinical automatic analyzer, but from the perspective of what should be a degasser to be incorporated into the device, considering both as one. The water tank has a sufficient function as a bubble separator, and is sufficiently effective if the floating bubbles are not directly sucked into the degassing device.

量で気泡分離を行うことも可能である。When the water tank is small and it is difficult to install the degassing device inside, the bubble separating function performed in the water tank is brought near the degassing device. In general, clinical automatic analyzers also use water that does not require degassing, so this pipe is used to guide water to a small room near the water inlet of the degassing device to be treated. It suffices to perform bubble separation and suck water containing no bubbles into the degassing device. As a matter of course, the water may flow into the small chamber from anywhere, but it is preferable that the water is discharged from the upper part and the suction to the degassing device is carried out from the bottom part. Further, when the diameter of the pipe is sufficiently large, it is possible to perform bubble separation with the pipe capacity without providing a small chamber.

る。Function: The gas permeable membrane type degassing device can remove only dissolved gas and will pass through the gas bubbles.
Therefore, the bubbles must be removed before entering the degasser. For that purpose, a bubble separation device may be provided immediately before the degassing device, and this bubble separation device has a cross-sectional area that makes the flow rate of water due to the degassing device sucking water sufficiently slower than the rising speed of the bubbles. Good. Ion-exchanged water storage tanks generally have a sufficient bubble separation function for this purpose, but when the storage tanks cannot be used, a degassed portion of water can be provided by providing a bubble separation chamber with the above functions at the treated water inlet of the degassing device. It is possible to prevent air bubbles from being mixed in, and by doing so, the performance of the degassing device can be fully exhibited.

良い方法ではない。FIG. 3 shows the simplest method according to the conventional method. The bubbles generated in the pipe 4 pass through the membrane separation module, are separated by the bubble separation device 5, and are accumulated as gas in the upper part, and the degassed water is It is used by suction by the pump 6.
The accumulated gas is manually removed by the valve 7. Although it works for some time, this is not a very good method because the gas accumulated in the separation device 5 may be redissolved.

性に乏しい。FIG. 4 is a conventional method, and the present invention is functionally the same in that a bubble separation device 5 is provided immediately before the degassing module 1 and only water containing no bubbles is sent to the degassing module. The difference is that an additional component to the degasser itself, that is, a separator 5 including a liquid level sensor 9 and a solenoid valve 8 that operates when the liquid level is detected are added to exhaust gas using a vacuum pump 2 of the degasser. That is, the idea of solving the problem by improving the degassing device as a single unit is different from the present invention. Although functionally sufficient performance is required, it sometimes involves problems such as water getting into the vacuum pump, which is complicated, expensive, and poor in reliability.

うな邪魔板をつけることが望ましい。FIG. 1 relates to a water tank dipping type according to the present invention, which is the simplest case in which the water tank 3 is sufficiently large and the degassing module 1 can be placed therein. The score is also the lowest. It is desirable to attach a baffle so that the floating water at the treated water inlet a of the degassing module does not get caught.

いるため何等制御を行う必要はなく気泡は排出される。FIG. 2 shows an embodiment of the present invention in which air bubbles are separated immediately before the degassing device.
An example is shown in case of not entering. The same as the conventional method of FIG. 4, but the point that the bubble separation device 5 is provided immediately before the degassing module 1 is regarded as the degassing device as a part of the clinical automatic measuring device, so that water containing bubbles requires degassing. It is sucked by the pump 10 which is not used. Since water always flows through this line, it is not necessary to control anything and bubbles are discharged.
