According to Ukrainian media reports, in January 2009, Uruguay signed a natural gas contract, which stipulated that the price of imported Russian natural gas in the first quarter of 2010 would be US$305 per 1,000 cubic meters, which was US$97 higher than in the fourth quarter of 2009.
In April 2010, Uzbekistan signed an agreement and Russia agreed to cut prices by about 30% on the basis of the original contract price to sell gas to Ukraine.
In the second quarter of 2010, the price of Ukrainian imports of Russian natural gas fell to US$232.8 per 1,000 cubic meters, in the third quarter it was US$248.7 per 1,000 cubic meters, and in the fourth quarter it was US$252.1 per 1,000 cubic meters.
Ozone is a chemical substance with the chemical formula O3. It is a strong oxidant with strong oxidizing ability. In the atmosphere, ozone is an important gas component that can participate in atmospheric chemical reactions and has an important impact on air quality and ecological environment.The principle of the ozone sensor is based on the electrochemical detection principle. Generally speaking, an ozone sensor consists of a working electrode, a reference electrode and an electrolyte. The working electrode and the reference electrode are connected through an electrolyte and immersed in the electrolyte. When ozone enters the interior of the sensor, it reacts with water molecules in the electrolyte to produce oxygen and hydrogen ions. These hydrogen ions generate an electric current on the working electrode, the magnitude of which is proportional to the ozone concentration. By measuring changes in electrical current, the concentration of ozone can be determined. Hydrogen peroxide sensors have a wide range of applications. It can be used for oxidant concentration detection in industrial process control, such as water treatment, food processing and pharmaceutical industries. In addition, hydrogen peroxide sensors can also be used in the medical field to detect hydrogen peroxide concentration in the human body, such as the correlation between hydrogen peroxide concentration in the blood and diseases. In addition, hydrogen peroxide sensors can also be used in the fields of environmental monitoring and food safety. If you want to buy online Ozone sensors, please contact us!
