Detection of sulfur dioxide at low parts per million

Aug 08, 2020·Sulfur dioxide(SO 2) is a toxic gas at low parts-per-million (ppm) concentrations, with a permissible exposure limit (PEL) of 2 ppm. Its detection is mandatory, particularly in the fields of occupational health and safety, and environmentalpollution.In this work,ppmconcentration detection ofsulfur dioxidewas performed in six room temperature ionic liquids (RTILs), as well as on two different …

Particle Monitors Archives A E group

Aerosol particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It also is useful in understanding the cleanliness level in a controlled environment. A common controlled environment aerosol particle counters are used in is a ...
