标准摘要
[中文适用范围]: 本文件规定了测定纤维素纳米材料悬浮液中干物质含量的烘干方法。 该程序适用于纤维素纳米材料悬浮液,除了水之外,不含有任何明显数量的在 105 °C ± 2 °C 温度下挥发的材料。 例如,当需要同时测定干物质含量时,它可用于实验室化学和物理测试中采集的纤维素纳米材料悬浮液样品。 注:本文件确定样品的总干物质含量,包括任何溶解的固体。 如果仅需要不含溶解固体的纤维素材料含量,则在测量干物质含量之前除去溶解固体,例如通过洗涤或透析,注意保留所有纤维素材料。 [外文原描述]: 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.
