Abstract

Notice The U.S. Environmental Protection Agency (EPA), through its Office of Research and Development (ORD), funded and managed, under Interagency Agreement No. DW89936700-01-0 with the U.S. Department of Energy=s Sandia National Laboratory, the verification effort described in this document. This report has received both technical peer and administrative policy reviews and has been approved for publication as an EPA document. Mention of corporate names, trade names, or commercial products does not constitute endorsement or recommendation for use. PROGRAM DESCRIPTION The U.S. Environmental Protection Agency (EPA) created the Environmental Technology Verification Program (ETV) to facilitate the deployment of innovative environmental technologies through performance verification and information dissemination. The goal of the ETV Program is to further environmental protection by substantially accelerating the acceptance and use of improved and cost-effective technologies. The ETV Program is intended to assist and inform those involved in the design, distribution, permitting, and purchase of environmental technologies. Under this program, in partnership with recognized testing organizations, and with the full participation of the technology developer, the EPA evaluates the performance of innovative technologies by developing demonstration plans, conducting field tests, collecting and analyzing the demonstration results, and preparing reports. The testing is conducted in accordance with rigorous quality assurance protocols to ensure that data of known and adequate quality are generated and that the results are defensible. The EPA National Exposure Research Laboratory, in cooperation with Sandia National Laboratories, the testing organization, evaluated field-portable systems for monitoring chlorinated volatile organic compounds (VOCs) in water. This verification statement provides a summary of the demonstration and results for the Inficon HAPSITE field-portable gas chromatograph/mass spectrometer (GC/MS) system. DEMONSTRATION DESCRIPTION The field demonstration of the HAPSITE portable GC/MS was held in September 1997. The demonstration was designed to assess the instrument's ability to detect and measure chlorinated volatile organic compounds in groundwater at two contaminated sites: the Department of Energy's Savannah River Site, near Aiken, South Carolina, and the McClellan Air Force Base, near Sacramento, California.

现场便携式气相色谱-质谱分析
美国环境保护署(EPA),通过其研究与发展办公室(ORD),根据机构间协议No. 5资助和管理。DW89936700-01-0与美国能源部桑迪亚国家实验室,验证工作在本文档中描述。该报告已接受技术同行和行政政策审查,并已批准作为EPA文件出版。提及公司名称、商品名称或商业产品不构成背书或推荐使用。美国环境保护署(EPA)设立了环境技术验证计划(ETV),通过绩效验证和信息传播促进创新环境技术的部署。ETV计划的目标是通过大幅加速接受和使用改进的和具有成本效益的技术来进一步保护环境。ETV计划旨在帮助和告知那些参与设计、分销、许可和购买环境技术的人员。根据这一方案,EPA与公认的测试组织合作,在技术开发人员的充分参与下,通过制定演示计划、进行实地测试、收集和分析演示结果以及编写报告来评估创新技术的性能。测试是按照严格的质量保证协议进行的,以确保生成已知和适当质量的数据,并确保结果是可辩护的。环境保护署国家接触研究实验室与测试组织桑迪亚国家实验室合作,评估了监测水中氯化挥发性有机化合物(VOCs)的现场便携式系统。本验证声明提供了Inficon HAPSITE现场便携式气相色谱仪/质谱仪(GC/MS)系统的演示和结果总结。1997年9月,HAPSITE便携式GC/MS进行了现场演示。该演示旨在评估该仪器在两个污染地点检测和测量地下水中氯化挥发性有机化合物的能力:南卡罗来纳州艾肯附近的能源部萨凡纳河地点和加利福尼亚州萨克拉门托附近的麦克莱伦空军基地。每个站点的地下水样品补充已知成分的性能评价(PE)样品。两种样品类型均用于评估仪器的准确性、精密度、样品通量以及与参考实验室结果的可比性。萨凡纳河遗址的主要目标化合物是三氯乙烯和四氯乙烯。在麦克莱伦空军基地,目标化合物是三氯乙烯、四氯乙烯、1,2-二氯乙烷、1,1,2 -三氯乙烷、1,2-二氯丙烷和反式-1,3-二氯丙烯。选择这些地点是因为它们含有不同浓度的……
