OREANDA-NEWS. October 19, 2009. The physical-chemical laboratory at NLMK's Industrial Ecology Department has begun using a new ultraviolet gas analyzer for continuous air contamination level measurement.  

By using the new equipment, the plant’s environmental specialists are able to control air quality dynamics at the production site, promptly reveal the sources of pollution and take measures to improve the condition of the air. 

This gas analyzer operation is based on the absorption of hazardous substances through UV radiation and quickly and automatically determines the concentration of 23 pollutants including nitrogen oxides, sulphur, formaldehyde, phenol and organic compounds. 

NLMK is currently the only company in the region with such unique equipment.
