U.S. Environmental Protection Agency Method 524.3 for Analysis of Volatile Organic Compounds (VOCs) in Finished Drinking Water: Optimized Instrument Parameters and Method Validation
美国环境保护局成品饮用水中挥发性有机化合物(VOCs)分析方法524.3:优化仪器参数和方法验证
The U.S. Environmental Protection Agency (USEPA) Office of Groundwater and Drinking Water released
Method 524.3 (1), "Measurement of Purgeable Organic Compounds in
Water by Capillary Column Gas Chromatography/Mass Spectrometry,
Revision 1.0," in the Federal Register (2), on August 3, 2009. The new
method is used for determination of volatile organic compounds (VOCs)
in finished drinking water, and includes several significant changes and
improvements over its predecessor, USEPA Method 524.2 (3).
This paper presents optimized instrument operating parameters,
including a 6-minute purge time, and a complete set of method validation
data. Quality control statistics shown here include calibration acceptance
data, Minimum Reporting Levels (MRLs), Detection Limits (DLs) and
Lowest Concentration Minimum Reporting Levels (LCMRLs); two
precision and accuracy studies from the Initial Demonstration of
Capability (IDC); and, results from Laboratory Reagent Blanks (LRBs)
and Continuing Calibration Check (CCC) samples. Includes 7 references, tables, figures.
