Scope
This document specifies an oven-drying method for the determination of the dry matter content
in suspensions of cellulosic nanomaterials. The procedure is applicable to cellulosic nanomaterial
suspensions which do not contain any appreciable quantities of materials other than water that are
volatile at the temperature of 105 °C ± 2 °C. It is used, for example, in the case of cellulosic nanomaterial
suspensions samples taken for chemical and physical tests in the laboratory, when a concurrent
determination of dry matter content is required.
NOTE This document determines the total dry matter content of the sample, including any dissolved solids.
If only the cellulosic material content free of dissolved solids is desired, dissolved solids are removed prior to
measuring the dry matter content, e.g. by washing or dialysis, taking care to retain all cellulosic material.
