Description

Technical Field

[0001] The present invention relates to the technical field of oxygen-18 water purity detection, and in particular to an adjustable oxygen-18 water purity detection device and detection method. Background Art

[0002] Heavy oxygen water, also known as oxygen-18 water, is water whose chemical formula H2O has oxygen atoms labeled with isotope oxygen-18, becoming H218O. Its physical state is a colorless, odorless and tasteless liquid. Some physical properties are slightly different from those of ordinary water. It is mainly used as an isotope tracer in scientific research fields such as chemistry, medicine, biology, agriculture, and geology. Oxygen-18 is a "labeled atom" and is therefore widely used in various disciplines such as chemistry, medicine, bioengineering, environmental science, and geology. When -18 water is used, a raw material entry inspection report needs to be submitted to the drug regulatory agency, so the purity of -18 water needs to be tested;

[0003] When testing the purity of -18 water, staff usually observe the amount of -18 water added with the naked eye, which makes it impossible to adjust the discharge amount of -18 water. Excessive discharge of -18 water can easily lead to waste of -18 water. At the same time, the oxygen generated by -18 water is tested, and oxygen cannot be tested centrally, resulting in a wide diffusion range of oxygen and affecting the detection quality. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides an adjustable oxygen-18 water purity detection device and detection method. The push rod can move downward to squeeze the movable plate, and the movable plate can tilt downward to squeeze the spring, so that the movable plate can be separated and the heavy oxygen water can be discharged into the interior of the liquid collecting tube through the liquid outlet pipe for collection. The discharge amount of the heavy oxygen water can be adjusted by the size of the opening separated by the movable plate, so that it is not easy to cause waste of heavy oxygen water. The rotating rod can drive the concave plate to rotate under the influence of oxygen flutter. The rotation of the concave plate can push the oxygen in the gas hood upward, so that the oxygen can be concentrated in the interior of the air pipe. The gas detector can detect the oxygen in a centralized manner, etc., which solves the problems that the discharge amount of -18 water cannot be adjusted and the oxygen cannot be detected in a centralized manner.

After the oxygen is heated, the heated oxygen can be discharged into the interior of the refrigeration box (7) using the connecting pipe (24). The oxygen in the refrigeration box (7) can be cooled using the semiconductor refrigerator (27), so that the oxygen can form condensed water and be discharged through the water outlet pipe (25) for collection and treatment.
