Ammonia analyzer

Ammonia analyzerProduct Overview:

The ammonia online analyzer developed by our company is based on the "Sodium hypochlorite salicylic acid spectrophotometric method for the determination of ammonia in ambient air" (HJ 534-2009). The measurement principle is that ammonia in the air is captured by a spiral tube trap under the action of a vacuum diaphragm pump, and fully contacts with the absorption liquid in the trap. The ammonia component in the gas to be measured is absorbed in the absorption liquid to obtain a test solution containing ammonium ions. In the presence of sodium ferrocyanide, ammonium ions, salicylic acid, and sodium hypochlorite react to form the blue complex indigo phenol blue, which has an absorbance of * at a wavelength of 697nm. The liquid subjected to derivatization reaction enters the total reflection long path online flow cell (LWCC) for the test sample. According to Lambert Beer's law, under the irradiation of a special light source with a wavelength of 697nm and a certain absorption layer thickness, the concentration of the test component is proportional to its absorbance. Online detection of ammonia content in the gas to be tested can be achieved based on absorbance.

Ammonia analyzerWidely applicable in various fields, including but not limited to the following:

1. Petrochemical and metallurgical mining industries: In these industries, it can be used to monitor ammonia leaks, prevent poisoning and explosion accidents, and ensure production safety.

2. Industrial manufacturing: During the manufacturing process, the concentration of ammonia can be monitored to ensure the safety of the working environment.

3. Municipal construction, power grid, and underground pipeline maintenance: In these areas, it helps to detect ammonia leaks in a timely manner, ensuring public safety and the normal operation of facilities.

4. Paper making, firefighting, biopharmaceuticals, and animal husbandry: These industries may also involve the use or production of ammonia, which has important applications in these fields.

5. Home environmental protection: can be used for monitoring the concentration of ammonia in the home environment, ensuring the health of the living environment.

6. University experiments and research institutions: can be used in scientific research and experiments to study the properties, reactions, etc. of ammonia gas.

7. In the field of agriculture, ammonia is one of the main volatile gases produced from fertilizer application and animal manure in farmland. By monitoring the concentration of ammonia, the amount of fertilizer can be adjusted in a timely manner, increasing crop yields and reducing negative impacts on the environment.

8. In the field of environmental protection, ammonia is an important pollutant in the atmosphere, and its emissions have a negative impact on air quality and ecological environment. Plays a key role in environmental monitoring, it can be used to monitor factory waste gas, livestock and poultry breeding waste gas, etc., to help evaluate and control ammonia emissions.
