The major objective of the project aims to develop sampling and analysis technology of halogenated organic pollutants in stack and provides test methods established to Environmental Analysis Laboratory, EPA. The on-line measurement method is based on NIEA method A722.75B, an off-line measurement method and collects sampling and analysis technology domestic and international. We sample halogenated organic pollutants by the sampling valve (2 position- 10 port) with one sample loop, two columns and analyse with GC-FID. We developed halogenated organic pollutants analyse technology, including methods of quality assurance standards, calibration, detection limits, precision accuracy, etc.,This project demonstrated the detection limits of these developed methods can match the currently EPA regulations for stack , and furthermore to provide draft standard operation procedure for EPA.
