Various recognized authorities have given the word “accuracy” different technical definitions, expressed in terms of bias and imprecision.

The quantity removed is not an evenly divisible part of the whole sample. An aliquot, by contrast, is an evenly divisible part of the whole. analyte: See TARGET ANALYTE. analytical protocol specification (APS): The output of a DIRECTED PLANNING PROCESS that contains the project’s analytical data needs and criteria in an organized, concise form. The level of specificity in the APS should be limited to those criteria that are considered essential to meeting the project’s analytical data criteria to allow the laboratory the flexibility of selecting the protocols or methods that meet the analytical criteria. as low as is reasonably achievable (ALARA): “As low as is reasonably achievable taking into account the state of the technology and the economics of improvements in relation to benefits to the public health and safety and other societal and socioeconomic considerations, and in relation to the use of atomic energy in the public interest” (10 USC 50.34a). assessment: A planned and documented activity performed to
