Development of Automated Monitoring System for Volatile Hazardous Air Pollutants using Average Sample Storage System/GC/MS

Abstract

An automated long term monitoring system for trace amounts of volatile organic hazardous air pollutants has been developed using capillary column GC/MS. Air sample was continuously compressed into stainless steel canister to determine average concentrations for every 2 hours-1 day. Two canisters were used alternately to keep continuity of sample collection. The performances of the automated monitoring system have been evaluated for every 1-day sampling condition, which is suitable to evaluate yearly average concentrations for risk assessment.
