| Resumen: | 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.
