TY - JOUR A1 - Liaskos, C. A1 - Rhoderick, G. A1 - Hodges, J. A1 - Possolo, A. A1 - Wilke, Olaf T1 - Pilot comparison CCQM-P177 - monoterpenes in nitrogen at 2.5 nmol/mol - final report N2 - Growing awareness of the impact of monoterpenes on climate, atmospheric chemistry, and indoor air quality has necessitated the development of measurement standards to globally monitor and control their emissions. For National Metrology Institutes to develop such standards, it is essential that they demonstrate measurement equivalence for assigned values at the highest levels of accuracy. This report describes the results of a pilot comparison for 4 key monoterpene species: α-pinene, 3-carene, R-limonene and 1,8-cineole, at a nominal amount-of-substance fraction of 2.5 nmol mol-1. The objective of this comparison is to evaluate participant capabilities to measure trace-level monoterpenes using their own calibration techniques.

This presentation is a gap analysis and stakeholder mapping for particles in air, from engineered to natural materials. The analysis was requested for the following points: (1) critical literature on stakeholder needs and relevant metrology (2) existing reference materials and relevant interlaboratory comparisons (3) relevant metrology projects (4) critical stakeholders and stakeholder networks and stakeholder surveys T2 - CCQM IAWG/SAWG TG Particle Metrology CY - Online meeting DA - 09.07.2024 KW - CCQM KW - Particle KW - Nano KW - Characterization KW - Aerosol PY - 2024 AN - OPUS4-62067 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
