| Resumen: | To establish international measurement capabilities for the determination of ethanol in aqueous matrices, the CCQM Organic Analysis Working Group (OAWG) has performed three ethanol Key comparisons (2002: CCQM-K27a for forensic aqueous ethanol and CCQM-K27b for ethanol in wine as a commodity; 2005: CCQM-K27 subsequent studies – four levels of ethanol in water; 2007: CCQMK27.2 Subsequent 2 for forensic levels). To provide an opportunity for the NMIs and DIs within the RMOs, three Key comparisons has been conducted within SIM (SIM.QM-K1, SIM.QM-K27) and AFRIMETS (AFRIMETS.QM-K27). In addition, for the NMIs to support their ethanol in aqueous matrices measurements capabilities, a Track A Model 2 (formerly known as Track B) Key comparison CCQM-K79 (2010) has been completed to compare aqueous ethanol certified reference material (CRM) solutions certified by the participant NMIs and DIs. The current comparison is important to NMIs and DIs to maintain their ethanol in water measurement capabilities, to claim it as a new one as well as to complement their existing measurement capabilities, mainly within the range where the alcohol meter (breathalyzer) needs to be calibrated and verified. |
