HEDS-IC를 이용한 환경대기 중 암모니아 연속측정에 관한 연구
Abstract
The ammonia in ambient were sampled by high efficiency diffusion scrubber (HEDS) and analyzed by IC. Ammonia showed high linearity (R²＞0.999) of the calibration curve and good repeatability (RSD＜5%). The detection limit of Ammonia was about 0.05 ppbv. Average concentration of Ammonia was 12.7 ppbv, Instantaneous maximum concentration was 83.4 ppbv. Continuous sampling method is proper to monitor ammonia which is the odor material instantaneously increased mainly affected by meteorological condition. The sampling and analysis process can be automated and performed in real-time by continuous sampling of HEDS-IC system.
