Phosphine gas monitor principle application

Phosphine gas (PH3) is a toxic gas that is mainly used in agriculture, chemical industry, and other fields. A phosphine gas monitor has become a necessary instrument for the detection of phosphine gas. This article will introduce the working principle and application field of Phosphine gas monitor.

Working Principle

A phosphine gas monitor is an instrument that monitors the concentration of phosphine gas using the Electrochemical gas sensor principle. When phosphine gas passes through the sampling device of the monitor, the catalyst in the sampling device promotes the oxidation of phosphine gas to form phosphate ions and water. At the same time, this reaction releases electrons, which are collected by the anode and cathode of the detector and converted into an electrical signal. The magnitude of the electrical signal is directly proportional to the concentration of phosphine gas, so by measuring the magnitude of the electrical signal, the concentration of phosphine gas can be determined.

Application

Agriculture: A phosphine gas monitor can be used to detect the concentration of phosphine gas in farmland soil to ensure the safety and quality of agricultural products. It can also be used to monitor the leakage of phosphine gas during the use of pesticides to prevent harm to the environment and human health.

Chemical industry: Phosphine gas may leak during chemical production, PH3 gas monitor can be used to monitor the concentration of phosphine gas in chemical plant areas in real-time to ensure the safety of workers’ lives.

Semiconductor Manufacturing: Phosphine gas is a gas commonly used in the semiconductor manufacturing process and is somewhat toxic. phosphine gas monitor can be used to monitor the concentration of phosphine gas in the semiconductor production line in real-time to ensure the safety of the production environment and to prevent the staff from being exposed to toxic gases.

Grain storage: Phosphine gas, a commonly used protective agent for grain storage, may leak in grain warehouses. ph3 gas monitor can be used to monitor the concentration of phosphine gas in warehouses in real-time to ensure the safety of food security and the storage environment.

Environmental monitoring: The concentration of phosphine gas in the atmosphere has an important impact on the quality of the environment and human health, Phosphine gas monitoring can be used for atmospheric environment monitoring, assessing the air quality, and providing a scientific basis for the environmental protection department.
