Title Estimating service lives of organic vapor cartridges
Bibliographic information Jan. 1994, Vol.55, No.1, p.11-15. Illus. 14 ref.
Abstract Procedures were developed for estimating service lives of air purifying organic vapour respirator cartridges, including methods for untested compounds and use conditions (concentration, temperature and airflow rate). Correlations of absorption capacities and adsorption-rate coefficients based on equilibrium and breakthrough curve data were reviewed. These correlations were combined using a reaction kinetic equation to estimate breakthrough times. Even limited breakthrough curve data for one vapour/carbon combination can be used to substantially improve the accuracy of the estimation. Only dry conditions (below 50% relative humidity) were considered.
