AOAC 2017 Annual Meeting Preliminary Program

SCIENTIFIC SESSIONS

SUNDAY, SEPTEMBER 24, 2017 1:00 PM – 2:30 PM TDLM Training Session: Traceability — An Important Requirement for ISO 17025 This workshop will include a discussion of traceability followed by an interactive exercise in which each participant identifies traceability components in an analytical procedure. Metrological traceability is a key element in the mutual recognition of calibration and testing results. ISO 17025 requires accredited laboratories to have a program in place to ensure that calibrations and measurements made by the laboratory are traceable to the International System of Units (SI) or to appropriate measurement standards where SI units cannot be realized. Many believe that using calibrated balances, volumetric glass ware, timers, thermometers, etc, is enough to fulfil traceability requirements. Contrary to this, it has to be appreciated that metrological traceability is just one of several determinants for producing valid and comparable measurement results; the others are proper method validation and a system of measures which ensures that analytical processes are under control. References to commonly accepted standards (measurement scales, such as the SI, reference materials, artefacts, reference methods) are of crucial importance for setting up traceability chains or for confirming metrological traceability. Such references must be chosen with care and can obviously not be restricted to physical input quantities (mass, volume, temperature, etc). Contemporary analytical chemistry relies to a large extent on measurement principles requiring some form of calibration to relate the signal generated by an instrument to a certain amount of substance; therefore, calibration materials that are well characterized with respect to their identity and purity very often form the starting point of a traceability chain.

3:00 PM – 4:30 PM TDRM Workshop: New ISO Series of Documents for Reference Material Producers For the first time ever, there is a coordinated, comprehensive series of documents from ISO containing requirements and guidance on production of reference materials. This includes all types of reference materials, not just Certified Reference Materials. These documents will form the basis of international efforts for increased availability of RMs, especially matrix RMs. Requirements and guidance cover all aspects of RM production, oversight, and use; public (i.e., NMI) and commercial production; traditional chemical calibrators and matrix materials with contaminants at levels of interest; and quantitative and qualitative property values, including RMs for identity, presence or absence, and purity. The workshop will offer brief perspectives from a national metrology institute and ISO REMCO member, an accredited RM producer, a multinational laboratory user, and an accreditation body.
