Beschreibung

ERM-FD103 consists of titanium dioxide nanorods in 1-butanol. The material is available in 5 mL pre-scored glass ampoules containing approximately 2 mL of suspension. The intended use is to check the performance of instruments and/or methods that characterise the morphology (i.e. size and shape) of nanorods (particles with two external dimensions in the size range of approximately 1 nm to 100 nm) that are deposited onto a suitable flat substrate. The certified values that have been assigned are regarded as reliable estimates of the true values and ERM-FD103 can therefore be used for calibration purposes. As a result of the material synthesis process and the physicochemical conditions of the suspension, agglomerates can be expected /// The uncertainty of the certified value is the expanded uncertainty with a coverage factor k = 2 corresponding to a level of confidence of about 95 % estimated in accordance with ISO/IEC Guide 98-3, Guide to the Expression of Uncertainty in Measurement (GUM:1995), ISO, 2008.
