Abstract |
Measurements were carried out in 6 rotogravure printing works; the tracer gases used were CO2, N2O and SF6. SF6 was best for marking large air masses; only a very small amount of this tracer was needed, and could be detected <4x10-5cm3/m3. CO2 measurements are best for small rooms and halls with a low ventilation rate. Cost aspects of measurement and analysis equipment are discussed. |
