Rapid on-line analysis for reduced sulfur compounds

该项目涉及制定直接进样和在线测量战略，以快速分析复杂环境样品中的挥发性和半挥发性有机化合物，包括烟道气和废水沃茨。其目的是发展在线分析技术，用于快速测量与特定工业有关的污染物，例如纸浆和造纸作业中的总还原硫化合物。这项工作扩展了膜引入质谱（MIMS）接口的使用和应用，该接口基于同轴热解吸策略，专门针对与空气质量退化和气味投诉相关的还原硫化合物的实时测量。该项目涉及膜的参数研究和表征

This project involves the development of direct sample introduction and on-line measurement strategies for rapid analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in complex environmental samples, including flue gases and waste waters. It is aimed at the development of on-line analytical techniques for the rapid measurement of pollutants associated with specific industries, such as total reduced sulfur compounds in pulp and paper operations. The work extends the use and application of a membrane introduction mass spectrometry (MIMS) interface based upon coaxial thermal desorption strategies targeted specifically for the real-time measurement of reduced sulfur compounds that are associated with air-quality degradation and odour complaints. The project involves parametric studies and characterization of membrane
