摘要

替代工具(AT),如现场测试工具包、现场便携式设备和连续测量设备,有助于改善欧盟指令下的水质评估和水处理过程,从而有助于改善水管理,并深入了解水体中污染物的动态。尽管这些工具具有明显的优势(如反应迅速,可进行实时监测,易于使用,成本较低),但它们被认为不如传统的分析方法可靠。它们的替代性、创新性和非标准操作模式要求采用与传统分析方法明显不同的特定验证策略。尽管如此,对自动监测仪,特别是用于水质监测的现场测试套件、便携式设备和连续测量设备进行验证,对于支持其被接受、促进其使用并使其应用具有可持续性至关重要。本文提出了一个分为 4 个步骤的验证程序:(1) 对自动监测仪进行全面描述;(2) 评估单个实验室的内在计量性能和操作因素;(3) 通过实验室间比较评估实验室间性能;(4) 证明自动监测仪与参考方法之间的结果等效。本文将讨论验证程序的每一个步骤,并举例说明关键问题。

Insights on the validation of alternative tools for water quality monitoring: the case of on-site test kits, portable devices and continuous measuring devices

Alternative Tools (AT) such as on-site test kits, on-site portable devices and continuous measuring devices, are useful to improve water quality assessment under EU directives, and water treatment processes, thus contributing to improving water management, as well as get insights on the dynamic of pollutants within water bodies. Although these tools have clear advantages (e.g. fast response allowing for real-time monitoring, ease-of-use, lower cost), they are perceived as less reliable than conventional analytical methods. Their alternative nature, innovative status, and non-standard operation mode require specific validation strategies that differ significantly from those of conventional analytical methods. Nevertheless, the validation of ATs, especially on-site test kits, portable devices and continuous measuring devices for water quality monitoring is crucial to support their acceptance, promote their use and make their application sustainable. In this paper, a validation procedure in 4 steps is proposed: (1) Comprehensive description of the AT; (2) Assessment of intrinsic metrological performance and operational factors within a single laboratory; (3) Assessment of inter-laboratory performances through an inter-laboratory comparison and, (4) Demonstration of the equivalence of results between the AT and a reference method. This paper discusses each step of the validation procedure, and examples to illustrate critical issues are provided.

期刊介绍: Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
