Remarks:
This CRM was prepared from brown rice grains. The brown rice grain of 81.00 g was sealed with a height of 5 cm in a polypropylene container (with an outside diameter of 55 mm and a height of 55 mm). And the container was sealed in an aluminum-coated bag. This CRM should be stored at a temperature between 5 °C and 35 °C in a clean place and shielded from light.

Intended Use:
This CRM is intended for use in controlling the precision of analyses and validating analytical methods and instruments used for determination of 134Cs and 137Cs in brown rice and rice.

Remarks:
This material consists of colloidal silica nanoparticles suspended in a water-based solution. The certified values have been obtained by: 1. Centrifugal liquid sedimentation (CLS): data obtained according to ISO 13318-1:2001 2. Dynamic light scattering (DLS) - cumulants method: data obtained according to ISO 22412:2008 applying the cumulants method described in ISO 13321:1996 3. Dynamic light scattering (DLS) – distribution calculation algorithms: data obtained applying distribution calculation algorithms such as non-negative least square (NNLS) and CONTIN for data analysis 4. Electron microscopy (EM): data obtained with transmission and scanning electron microscopy, counting only particles with an equivalent diameter larger than 60 nm. 5. Particle tracking analysis (PTA): data obtained according to ISO 19430:2016 6. Small-angle X-ray scattering (SAXS): data obtained according to ISO 17867:2015 The material is available in 10 mL pre-scored glass ampoules containing approximately 9 mL of suspension.The material shall be stored at 18 °C ± 5 °C. Samples must not be allowed to freeze, as this will irreversibly compromise the integrity of the material. *** For more information see https://crm.jrc.ec.europa.eu/p/ERM-FD101b *** Additional keywords: nanoparticle, nanomaterial

Intended Use:
The intended use of ERM-FD101b is to check the performance of instruments and/or methods that characterise the size distribution of particles around 100 nm, that are either suspended in a liquid medium or deposited onto a suitable substrate. The certified values are regarded as reliable estimates of the true values and ERM-FD101b can therefore be used for calibration purposes.
