Tritiated water is a radioactive form of water where the usual protium atoms are replaced with tritium. In its pure form it may be called tritium oxide (T₂O or ³H₂O) or super-heavy water. Pure T₂O is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H₂O plus some HTO (³HOH). It is also used as a tracer for water transport studies in life-science research. Furthermore, since it naturally occurs in minute quantities, it can be used to determine the age of various water-based liquids, such as vintage wines.
An all-weather air tritiated water sampling method and system
The application discloses a kind of air tritiated water sampling method and system for all-weather, it is related to air tritiated water sampling field, the method comprises: four kinds of environmental parameters of temperature, relative humidity, atmospheric pressure and air flow rate of sampling point are acquired in real time;The environmental parameters acquired in real time are input to the preset dynamic parameter generator, and output a set of optimized key sampling parameter combination;According to the optimized key sampling parameter combination, dynamically adjust sampling pump, temperature adjusting device to execute sampling operation;In the whole sampling cycle, the effective adsorption capacity of adsorbent is continuously monitored, and the early warning information of adsorbent replacement is provided to the user.The problems such as condensation icing, adsorbent premature saturation or resolution under all-weather can be effectively avoided by the application, and the sampling efficiency and accuracy are significantly improved;At the same time, through adsorbent residual capacity monitoring and failure warning, the sampling is continuously stable, and high-precision, intelligent air tritiated water sampling under any weather condition is realized.
