An automated cleanup system (Power-Prep, Fluid Management Systems, Inc.) was evaluated for the analysis of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) in environmental samples. The study was firstly carried out against standard mixtures containing labeled and unlabeled PCDD/PCDF and a certified reference material (fly ash CRM 490). Next, a comparison between a conventional cleanup procedure and the new automated system for PCDD/PCDF analysis in environmental samples such as flue gas emissions, fly ashes, sludges, ambient air and soils was also made. The suitability of the system was finally assessed from the participation in an interlaboratory exercise. Owing to its capability to successfully perform the sample cleanup the Power-Prep apparatus is an alternative to the conventional methods.
对一种自动净化系统(Power-Prep,流体管理系统公司)进行了评估,用于分析环境样品中的多氯二苯并对二恶英和二苯并呋喃(PCDD/PCDF)。该研究首先针对含有标记和未标记PCDD/PCDF的标准混合物以及一种有证标准物质(飞灰CRM 490)展开。接下来,还对传统净化程序与用于分析烟道气排放、飞灰、污泥、环境空气和土壤等环境样品中PCDD/PCDF的新型自动系统进行了比较。最后,通过参与实验室间比对试验评估了该系统的适用性。由于其能够成功完成样品净化,Power-Prep仪器是传统方法的一种替代方案。
