The purposes of this project are to evaluate and establish ambient air sampling and analysis method for high solubility and strong polarity chemicals such as acrylamide, caprolactam, dimethyl sulfoxide and dimethyl formamide、methylamine、dimethylamine、ethylamine and trimethylamine. The ambient air sampling and analysis method includes adsorbent samplig, sample collection, preservation and instrumental analysis. Through five different ambient air sampling programs at the ambient of various factories, the ambient air sampling and analysis method was tested and verified its effectiveness and the quality control/quality assurance protocol. Technical transfer meetings were also held twice to encompass the thorough goal of this project.
Because of the high solubility and strong polarity of target chemicals, most factories applied scrubbers to clean up their exhaust gas, then emit through stacks and become potential odor sources. The required task issues including sampling requirement, the sampling flowrate of 0.1-0.2 lpm was recommended as the upper limit to avoid possible breakthrough.
Gas Chromatography equipped with flame ionization detector (GC/FID) and high performance liquid chromatography (HPLC) associated with Fluorescene detector (FLD) were applied to all three sampling and analysis methods. All target compounds were tested from the beginning of sampling, followed by analytical protocals, and finalized by appropriate detectors. Three analytical methods were proposed according to the previous research and results.
