This paper reviews the use of electron capture and flame photometric detectors in ambient air measurements, with particular emphasis on the factors which may affect the sensitivity, precision, and accuracy of the analyses. The interference effects of oxygen, water, and other common constituents in air samples are discussed. In addition to those anomalies that are due to the nature of the analytical samples, certain limitations are imposed by the inherent response characteristics of the detectors. These notable difficulties and limitations are defined along with their potential consequences in atmospheric applications. The basic intent of the discussion is to warn environmental scientists, who use the ECD and FPD, that significant errors can occur in their results unless they adhere to the analytical requirements of the analysis. Therefore, it is necessary to validate the ECD and FPD measurement techniques for their appropriateness in each new analytical application.
本文综述了电子捕获检测器和火焰光度检测器在环境空气测量中的应用，特别强调了可能影响分析灵敏度、精密度和准确度的因素。讨论了空气样品中氧气、水和其他常见成分的干扰效应。除了由于分析样品的性质导致的那些异常情况外，检测器的固有响应特性也会带来某些限制。这些显著的困难和限制连同它们在大气应用中的潜在后果一起被阐明。讨论的基本目的是提醒使用电子捕获检测器和火焰光度检测器的环境科学家，除非他们遵守分析的要求，否则他们的结果可能会出现重大误差。因此，有必要针对每种新的分析应用验证电子捕获检测器和火焰光度检测器测量技术的适用性。
