Visa, mature humidity measurement technology for plasma research contributions of the institute of Belgrade
Outside of the plasma is a solid, liquid and gas substances in the fourth state, with a large amount of internal energy positive ions, negative, neutral molecules, ultraviolet light and stimulating molecules.Plasma by gas conversion, the conversion method and liquid into gas and solid into liquid in the same way, namely by applying energy to achieve.
In recent years, under the condition of atmospheric plasma has become an important tool for scientific research, the scope of its application is increasingly wide.(Institute of Physics, Institute of Physics, in Belgrade, Serbia Belgrade), researchers are using visa to pull out of the compact DMT143 dew point transmitter to experiment, to explore the new applications of atmospheric pressure plasma treatment such as cancer cells.
Multifunctional tool suitable for biomedical applications
Belgrade, institute of physics researches in plasma is one of the European centre for the study of superior strength, has 25 laboratories and 200 researchers.The institute funded by Serbia's Ministry of Education, one of the laboratories of research emphasis is application research on using low pressure plasma under normal temperature.It is at this point, visa dew point transmitter technology contributed to the exciting new scientific discovery.
"Over the past decade, atmospheric pressure cold plasma (room temperature) is more and more widely used in medical and agricultural research, etc."The primary researcher Andjelija Petrovic explained."Unlike hot plasma, cold plasma won't destroy the biological samples, thus can be safely used in these areas.Cold plasma can promote seed germination, at the same time of killing cancer cells without damaging healthy cells."She continued.More of this kind of plasma application examples including wound treatment, pathogens such as bacteria and viruses inactivated, medical equipment, disinfection and water quality purification.
The significance of humidity
By adjusting the proportion of nitrogen and oxygen atoms in the gas mixture, how much of the energy used as well as the energy source, pressure, humidity and other factors, to adjust and control the influence of the plasma.Nowadays, plasma technology is widely used in automobiles, microelectronics, encapsulation and medical equipment and other industries, due to different industry demand for plasma, so need to adjust plasma.
"Measuring and monitoring the humidity in the plasma system is very important.Because of the water (H2O) molecules can induce many subsequent plasma chemical reaction, so the humidity in the plasma plays an important role in chemical process."Andeljija said."Water reaction process in the middle of the product, such as hydroxyl radicals (OH), and atomic oxygen (O) and hydrogen peroxide (H2O2), can cause oxidative risk to biological samples, "Andjelija explains," in biomedical applications, change the humidity will not only affect the plasma, will also affect the biological processing target, the target of this type may be a cell or cell structure, may also be a liquid or seeds."
Visa DMT143 - trustworthy team members
Because the plasma experiments using Andeljija auxiliary is small, soVisa miniature DMT143 dew point transmitterIs the ideal choice."Gases in the gas bottle into only 6 mm in diameter, length, only 20 centimeters of the glass tube.Glass tube with two electrodes can ignite gas, "Andeljija explains," DMT143 is installed in the gas pipeline between the bottle and the reaction tube.Before we can use it to observe into air humidity level, and to observe the influence of humidity on air.Once we ignite gas to generate the plasma, we can use the DMT143 measurements accurately control the humidity level, thus according to the need to control the plasma chemical reaction."Pictured above.
Laboratory has two Vaisala DMT143 equipment, have been used for six years."Accurate humidity measurement is vital for our work, over the years, we have relied on visa DMT143.This equipment use method is simple, and because of the small, we don't have to change the experiment set can integrate use, can also according to the need to move."Andeljija explained.
As Andeljija and his team continue to new field of plasma research and application of the visa DMT143 equipment will continue to play an important role, and help them in this hopeful field of scientific experiments to realize new breakthrough.
