Description
|
CNCS-1 is a cellulose nanocrystal suspension Certified Reference Material (CRM) from the National Research Council Canada (NRC) with information on total trace elements and several physico-chemical parameters such as elemental/molecular composition, specific surface area, surface chemistry, particle size and distribution, morphology/shape/form, surface charge and crystal structure. This CRM is intended primarily for use in the validation of procedures and development of methods for the determination of trace metals in cellulosic nanomaterials or those of a similar matrix. It has been gamma sterilized to support studies of environmental health and safety and nanotoxicology. CNCS-1 also serves as a stable and homogeneous representative test material to foster development and validation of international consensus-
based standards to further rigorous physico-chemical characterization of CNC and similar or related cellulosic-based nanomaterials.
