Remarks:
ERM-DA481/IFCC is part of a series of three cerebrospinal fluid (CSF) certified reference materials (CRMs) containing different levels of the amyloid β1-42 peptide (Aβ1-42) (Abeta 42). Abeta 42 is used as biomarker in the early diagnosis of Alzheimer's disease. The CRMs are available in microvials containing at least 0.5 mL of frozen liquid. The materials should be stored at -70 ± 10 °C. *** For more information see https://crm.jrc.ec.europa.eu/p/ERM-DA481_IFCC *** Additional keywords: CSF amyloid ß1-42 peptide Aß1-42 Alzheimer's, laboratory medicine

Intended Use:
The materials are intended for the calibration of methods, quality control and/or the assessment of method performance. As with any reference material, they can be used for establishing control charts or in validation studies.

Remarks:
ERM-FD103 is a titanium dioxide nanorod material certified for different particle size and shape parameters as determined by electron microscopy and image analysis according to ISO 13322-1. The certified values are expressed as: . Minimum Feret diameter (Fmin; minimum distance between two parallel tangents to opposite sides of the particle) · Maximum Feret diameter (Fmax; maximum distance between two parallel tangents to opposite sides of the particle) · Maximum inscribed circle diameter (diameter of the largest circle that fits into the particle profile) · Area-equivalent diameter or equivalent circular diameter (ECD; diameter of a circle having the same projection area as the particle) · Aspect ratio (Fmin/Fmax) The material is available in 5 mL pre-scored glass ampoules containing approximately 2 mL of suspension. The material shall be stored at 18 °C ± 5 °C in the dark. *** For more information see https://crm.jrc.ec.europa.eu/p/ERM-FD103 *** Additional keywords: nanoparticle, nanomaterial

Intended Use:
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.
