  • 本研究主要是利用熱脫附/氣相層析質譜儀來分析空氣中微量的半揮發性有機化合物(SVOCs),撘配幫浦及用自動連續採樣器採樣,吸附劑選用Tenax-TA (60-80 mesh)作為採樣介質,可以分析n-C6~n-C20的直鏈烷類及五種鄰苯二甲酸酯類,可以分析沸點高達386 ℃的化合物(DOP),偵測極限可以到達ppt的範圍。選擇居家生活圈與工作場合兩種污染區域做實測,室內空氣中可能的高沸點汙染源來做分析,想要找出危害人體健康之半揮發性有機化合物,包括女用香水的成分分析及溫度差異大的汽車內空氣品質分析,女用香水A、B、C分析結果發現香味濃郁的香水C中含有鄰苯二甲酸甲酯(DEP)。將汽車零件置於室溫及70 ℃的玻璃腔中採樣,70 ℃時的汙染物濃度比室溫高出很多,於地毯素材分析出鄰苯二甲酸二辛酯(DOP)。高科技產業實測分析結果一般來說液晶顯示器廠汙染濃度高於半導體廠,測得鄰苯二甲酸丁酯(DBP)及N-甲基2-四氫吡咯酮(NMP)等可凝結性有機污染物(Condensables, Class MC),目前熱門的環保產業太陽能電池廠分析結果發現SVOCs的污染濃度較高,因其製程中使用相當多SVOCs的溶劑,分析出Terpineol及DBP等特殊製程溶劑。實測結果發現由香水的使用到出門開車,接著進入高科技廠上班,其實整個生活圈中都暴露在SVOCs的污染之中,此方法可以補足現有分析方法的不足,希望未來在國內可以建立起SVOCs的標準分析方法。


    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.
