摘要
干燥失重是固体化合物的一类非常重要的检测指标,不仅可以用于评价产品品质好坏,而且是分析产品变质原因的重要线索。干燥失重通常包括易挥发的游离水和结晶水以及低沸点的有机物等。本文以硫氰酸钠105℃挥发物的测定为例,研究了固体化合物干燥失重检测过程中各因素对检测结果不确定度的影响。
Loss on drying is a kind of detection index of solid compound , it is used for evaluation of product quality, and it can be used to analysis the reason why product deterioration. Loss on drying usually include free water, crystallization water and low boiling point organic materials, etc. The paper studied the effects of factors which in the process of testing to the uncertainty evaluation of weight loss on drying test results , and the study is based on the determination of sodium thioeyanate which treated at 105℃ as an example.
