A need for the simplified review of method performance capability based on precision statement is required for commercial analytical instruments. A simplified applied statistical approach would benefit and assist laboratory managers, process engineers, commercial traders, lab chemists, lab technicians and operators. The numerical expression rating system based on performance relative to two or more points within the operating value of each parameter is defined in any standard method containing full precision, and is defined as repeatability and reproducibility. A process and computational expression is described and defined as analytical performance value (APV).
This newly devised performance value would be contained in any standard method for use as a quantitative evaluation of test method performance. The proposed technique is to define a systematic method which provides for establishing an analytical performance value based on precision criteria relative to parameter measurements. The APV can be expressed as a scaled value percentage, which can then be used to assess acceptability and capability of the instrument or test method. This poster discusses the derivation of the APV methodology and analyzes two examples from the oil and gas industry of a repeatability and reproducibility assessment by applying the APV technique to these two ASTM methods.
