性质:比重瓶法是称重测定物质密度最基本的方法之一,也是密度法分析重水的基本方法。可直接测定0%~100%重水的浓度。采用比重瓶-氧质谱法作重水成品分析的仲裁方法。而浮沉子法通常用于分析极稀的重水样品,是研究水同位素丰度的主要方法。干涉仪法是测定折射率分析重水的一种方法。用放电管中无电极的高频放电作光谱的激发电源,带平面衍射光栅自准直单色仪或专用的分光仪检测。分析速度快,曾用来监控重水生产。光谱法还用于水化物和含水晶体研究。测定人体血液中D2O的含量以及脏器中水的交换研究。氕和氘核自旋量子数分别为1/2和1,均是核磁共振核。氕是氢同位素中最适合作核磁共振测定的核。重水分析时,先将水样转化为气样,用核磁共振测定浓重水中的微量氕,精确度达±0.01%。红外光谱法用于测定已知和未知水样的吸收率,测定样品的氘浓度。分析灵敏度可达0.005%D2O。气相色谱法则测量精度为±0.005%D,0.1%D以下的样品,精度可达±0.001%D。另外也用质谱法-落滴法等作重水分析。
