The employment of an in-house-made capillary electrophoresis (CE) instrument with capacitively coupled contactless conductivity detection (C(4)D) as a simple and inexpensive solution for simultaneous determination of many rare earth elements (REEs) in ore samples from Vietnam, as well as in anti-corrosion coating samples is reported. 14 REEs (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) were determined using an electrolyte composed of 20mM arginine and 10mM α-hydroxyisobutyric acid adjusted to pH 4.2 with acetic acid. The best detection limit achieved was 0.24mg/L using the developed CE-C(4)D method. Good agreement between results from CE-C(4)D and the confirmation method (ICP-MS) was achieved, with a coefficient of determination (r(2)) for the two pairs of data of 0.998.
报道了使用自制的毛细管电泳（CE）仪器结合电容耦合非接触电导检测（C(4)D）作为一种简单且廉价的解决方案，用于同时测定越南矿石样品以及防腐涂层样品中的多种稀土元素（REEs）。使用由20mM精氨酸和10mM α-羟基异丁酸组成、用乙酸调节至pH 4.2的电解质来测定14种稀土元素（镧、铈、镨、钕、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥）。使用所开发的CE-C(4)D方法实现的最佳检测限为0.24mg/L。CE-C(4)D结果与确证方法（电感耦合等离子体质谱法，ICP-MS）之间达成了良好的一致性，两对数据的决定系数（r(2)）为0.998。
