卤素水份测定仪通常也被称为水份仪或水份分析仪。它是由称量单元和加热单元(红外技术)组成,是基于干燥失重原理来测定样品的水份含量。

卤素水份测定仪是如何工作的?

卤素水份测定仪的工作原理是基于热失重分析法,即通常所说的‘干燥失重’(LOD)原理由两部分组成,称量和加热单元。为了测定水份含量,样品的初始质量被仪器记录,然后卤素灯管开始加热并干燥样品,同时内置的称量单元不间断的对样品进行称量并记录数据。当样品不再失重(相对恒重)时,仪器停止加热并自动计算水份含量结果。样品总质量的差值被用来计算样品的水份含量。

谁会用到卤素水份测定仪?

烘箱法通常是测定水份含量的标准(国标)方法。目前,许多客户也在使用卤素水份测定仪,因为他们想更快地得到水份含量的分析结果。卤素水份测定仪已被运用于很多行业,例如食品、化工、制药和塑料。对于食品行业而言,水份含量测定尤其关键,因为这会影响到产品的质量和保质期。
