The goal of sampling is to take a small portion of a target material for analysis instead of collecting all the material. If sampling is done following certain principles, then inference can be made from analytical results of the portion taken back to the entire target material (Decision Unit). There are different sampling strategies that are dependent on the properties of the material being sampled as well as different methods for making inferences from analytical results to the Decision Unit (DU). A thorough understanding of material properties and methods for inference is therefore critical for the development of proper sampling protocols. This paper addresses inferences from analytical test results to DUs and the implications to the development of a sampling protocol.
采样的目的是取一小部分目标材料进行分析,而不是收集所有材料。如果按照某些原则进行采样,那么就可以根据所取部分的分析结果推断整个目标材料(决策单元)的情况。有不同的采样策略,这取决于被采样材料的特性,以及从分析结果推断到决策单元(DU)的不同方法。因此,全面了解材料特性和推断方法对于制定合适的采样方案至关重要。本文探讨了从分析测试结果到决策单元的推断以及对采样方案制定的影响。
