Description

Technical Field

[0001] The invention relates to the technical field of nanometer low-deuterium water preparation, and in particular to a portable detection device and a detection method for nanometer low-deuterium water concentration. Background Art

[0002] Deuterium-depleted water, also known as light water, refers to water with a deuterium content of less than 150ppm. Relevant studies have shown that deuterium-depleted water has a variety of biological effects that are beneficial to the human body: 1) It significantly promotes enzyme reactions, improves basal metabolism, and helps activate body cells; 2) It increases the activity of NK cells and enhances the body's immune function; 3) It reduces the content of heavy water, reduces the living environment of cancer cells, increases blood oxygen content and oxygen absorption, improves cell immunity, and restores the overall function of cell tissues, organs, and systems, so it can reduce tumor index values ​​and inhibit the proliferation of degraded cells and cancer cells.

[0003] Drinking deuterium-depleted water has a significant effect on alleviating related diseases. The deuterium content, i.e., concentration, of deuterium-depleted water plays a decisive role. At the same time, the lower the concentration of deuterium-depleted water, the higher the manufacturing cost. Deuterium-depleted water of different PPM has different application scenarios:

[0004] 10PPM deuterium-depleted water can be used as a medical injection reagent for severe cancer patients and as an adjuvant treatment for cancer;

[0005] 25PPPM deuterium-depleted water can be used for the prevention and adjuvant treatment of chronic diseases and can enhance immunity;

[0006] 50PPM low-deuterium water can repair genes, regulate vasodilation, lower blood lipids, and protect the cardiovascular system;

[0007] 80PPM low-deuterium water can be used for adjuvant tumor treatment, lower fasting blood sugar levels, and alleviate insulin resistance;

[0008] 100PPM low-deuterium water can prevent depression and enhance the body's basal metabolic capacity;

[0009] 110PPM low-deuterium water can relieve fatigue, reduce edema, improve sleep, delay aging, etc.

[0010] In real life, in order to ensure the quality of the final product, the concentration of deuterium-depleted water needs to be continuously measured. At present, the commonly used methods are mainly mass spectrometry, atomic absorption spectroscopy and nuclear magnetic resonance, adsorption and laser scattering. Since most of these methods require expensive instruments, cumbersome equipment maintenance, complex operation, professional personnel are required to operate, and the measurement cycle is long, they are not suitable for multiple measurements during production and sales.
