碩士 === 國立清華大學 === 原子科學系 === 94 === In this investigation, it was analyzed the Trace high boiling point Organic Compounds in the air by the TD-GC/MS. The adsorbent was selected the Tenax-TA (60-80 mesh) that can analysis the n-C6~n-C20 n-alkanes and five kind of phthalate esters as a medium for sampling and the sampling used the pump and auto-continual sampling equipment. That could analyzed compound that boiling point arrived 386 ℃, and detection limit was ppt. Detection range include daily livings and workplace. In daily livings, we chosen the contamination of high boiling point to analyze, include ingredient analysis of the female perfume and the air quality in the car that had a variation temperature that could have toxic SVOCs. The analysis result of female perfume A、B and C indicate that strong fragrance perfume C contained DEP. We sampled the accessory of a car under the room temperature and 70 ℃, the result indicate that the pollution produce at 70 ℃ more than room temperature, The large amount of esters would produce after heating and the walnut bar would have the most esters. There was DOP in carpeting.The analytic result of high Technology industry was that the contaminated concentration of semiconductor factory was lower than TFT-LCD factory., there was DBP and NMP belong to AMC in AMC’s definition. The sampling result of environmental protection industry-solar cell factory could find that the concentration of SVOCs was higher than befor both. Becouse the process used many SVOCs to be solvents. The special solvents include Terpineol and DBP…etc. We can find that contamination of SVOCs is everywhere. We could ues this method to anlysis SVOCs and to make up a deficiency for the methods that used before. In the future, hope that the standard methods for SVOCs anlysis could be set up.
