Certification of the alcoholic strength, δ13C and deuterium isotopic ratio in ethanol from grape sugar fermentation (ca. 96 % vol.): ERM®-AE201
ERM-AE201 is an ethanol based material certified for the deuterium-to-hydrogen (D/H) amount-of-substance ratios, the relative deuterium-to-hydrogen ratio (R), the δ13C value and the alcoholic strength mass fraction. The material was produced within the scope of ISO 17034:2016 accreditation and in accordance with ISO Guide 35:2017.
The certified reference material (CRM) is available in glass ampoules containing 10 mL of ethanol.
Between-unit homogeneity was quantified and stability during transport and storage was assessed in accordance with ISO Guide 35:2017. The minimum sample size for one measurement of the deuterium-to-hydrogen (D/H) amount-of-substance ratios and the relative deuterium-to-hydrogen ratio content is defined by the standard method OIV-MA-AS311-05. The δ13C and alcoholic strength minimum sample sizes were defined by the results derived from the characterisation studies.
The CRM was characterised by an interlaboratory comparison of laboratories of demonstrated competence and adhering to ISO/IEC 17025:2017. All data sets were technically valid and outliers were retained.
Uncertainties were derived in accordance with ISO 17034:2016 and ISO Guide 35:2017 and include possible inhomogeneity, instability and characterisation.
The material is used for quality control, for the assessment of method performance, for establishing control charts or during validation studies.
Before release of the CRM, the project was peer-reviewed by internal and external experts.
