标准范围

该方法基于称量试样并将其置于准备好的点火坩埚中,在低火焰上加热坩埚以去除任何挥发性物质,在炉中焚烧,在干燥器中冷却至室温,然后重新称重。

The method is based on weighing a test portion and placing it in prepared ignition crucible, heating the crucible over a low flame to drive off any volatile matter, incineration in a furnace, cooling to room temperature in a desiccator, and reweighing.
