Summary

Long-path gas monitoring by diode laser in the open atmosphere is a most useful technique for measuring industrial gas emissions. It has a number of advantages over point monitoring and is particularly suitable for the observation of large industrial areas. Its potential applications include boundary fence environmental gas monitoring, safety monitoring around and within industrial plant and the measurement of both gas flux and total site gas emission rates. A mobile long-path diode laser system has been developed to demonstrate these applications and measurements on a variety of sites are briefly described, involving monitoring of methane, ethane, ethylene, ammonia and carbon monoxide.
