特殊指標鑑定技術的建立與調查應用計畫(一)--建立安定性同位素分析技術
| 中文摘要 | 本計畫目標為建立以安定性同位素分析技術為主體之環境法醫應用鑑定技術，使實際應用於環境污染案件產源追查或關聯性鑑定上，以提升國內環境法醫鑑定技術的層次與能力。 本計畫建立GC-IRMS CSIA之精密度、準確度等品質績效數據。彙整24篇相關文獻，待測物包括多氯聯苯、有機氯溶劑、汽油等。應用範圍包括污染源鑑定及整治復育成效評估。建議94年度工作為「地下水有機溶劑污染案」之污染源檢驗比對鑑識和整治成效關聯性鑑定；95年度工作為「中石化安順廠址污染專案調查」污染源檢驗比對鑑識和及整治之和整治復育成效評估。ThermoFinnigan DeltaPLUS Advantage + GC/C-III interface Trace GC GC-IRMS儀器之準備包括：擬定儀器租售規格、採購標準氣體和標準品、4.4.3 準備空間與環境、裝機驗收、人員訓練、撰寫標準操作程序。儀器於2004-8-11運送至清華大學；2004-8-16開始進行裝機、3Q測試及人員操作訓練。2004-9-22完成驗收。因缺dual inlet，無法校驗質譜儀感度大於1離子/1200二氧化碳分子外，請原廠出具證明書。餘皆符合工作內容。並依據訓練內容和實作經驗，完成「GC-IRMS儀器標準操作程序」及「GC-IRMS儀器校驗程序」。 探討儀器分析條件，得知：(1) Mix-B Calibrator感度在數十ng範圍，Aroclor 感度在數百ng範圍；不同物種之感度差異，差別不大。(2)以Mix-B Calibrator及CO2參考氣體，測試儀器之精密度，同日內精密度平均標準偏差0.20~0.36?(CV=0.63~1.09％)，異日間精密度平均標準偏差0.29?(CV=0.93％)；(3) 以Mix-B Calibrator及CO2參考氣體，測試儀器之準確度，實測值與參考值差異在0.07~0.63?間，十二種成分在0.30?以內。(4)不同品牌二氯甲烷，可以13C安定性同位素分析技術辨別，初步證實94年度計畫之可行性。建議進行94年度「地下水有機溶劑污染案」之污染源檢驗比對鑑識和整治成效關聯性鑑定。 | ||

Establishment and Application of CSIA technology Plane sec.1--Establishment of Stable Isotope Analysis technology
| 英文摘要 | Set up performance data of quality , such as precision, accuracy of GC-IRMS CSIA ,etc. in this plan. Gather together 24 whole relevant documents, await measuring the thing including many chlorine unite the benzene , organic chlorine solvent , petrol etc.. The range of application including pollution sources determines and renovates and replies the effect of breeding to assess. Propose that the work examined and knew and renovated the related qualification of the effect than to the ancient bronze mirror for the pollution sources of # the organic solvent polluting case of groundwater # in 2005; One year work is it is it educate effect assess to reply to renovate for # China Petrochemical Industry Anshun site of factory pollute special project investigate # pollution sources examine than know to ancient bronze mirror and and renovate. The planning to include of ThermoFinnigan DeltaPLUS Advantage + GC/C-III interface Trace GC GC-IRMS instrument: Draft that the instrument rent and sell the specification , purchases the standard gas and standard product , prepares the space and environment , installation confirmation , personnel and trains , writes S.O.P. on 4.4.3. The instrument transports to Tsing-Hua University in 2004-8-11; Begin to test installation, 3Q by 2004-8-16 and personnel operate and train. 2004-9-22 finishes confirming. Because lack dual inlet, unable check-up mass spectrograph sense degree greater than 1 ion / 1200 carbon dioxide outside the member , ask the former factory to provide the testimonial. I all accord with the working content. And according to training the content and doing experience in fact, finish # GC-IRMS instrument S.O.P. # and # GC-IRMS instrument check-up procedure #. Probe into the instrument and analyse the condition , we learn : (1)Mix-B Calibrator sense degree is on several dozen ng ranges, Aroclor sense degree is on several hundred ng ranges; One degree of differences of sense of different species, the difference is not big. (2)Consult the gas with Mix-B Calibrator and CO2, the p | ||
