On-line membrane extraction microtrap gas chromatography (OLMEM-GC) for continuous monitoring of VOCs
- New Jersey Institute of Technology, Newark, NJ (United States)
Analysis of organic pollutants from air or water usually involves a separation step where the analytes are first separated from the matrix. Purging of VOCs from water in purge and trap analysis, and sorbent trapping of VOCs in air sampling are examples of such separations. These conventional methods are not readily usable for continues, on-line monitoring. To develop continuous monitoring techniques, it is important to develop methodologies where the separation of organics from the environmental matrix can be carried out on-line in a continuous fashion. The objective of this research is to develop analytical technique based on membrane separation for on-line GC monitoring of organic pollutants from air as well as water. The permeated VOCs will be pneumatically transported to the GC using a carrier gas. On-line trapping and injection of the organics into a GC will be done using a micro-sorbent trap.
