稀土及过渡金属有机化合物,因其有厌氧、吸湿,难以分解等特性,往往使分析得不到满意的结果。特别是取样技术方面的报导很少,而这一步却是很关键的。我们探索了几种取样技术,在此作一介绍。一、液体样品的称取我们设计了能在内部预先装入氧化剂的称样玻璃毛细管,目的是使样品均匀吸附在氧化剂表面,而使分解完全(图1)。二、固体样品的称取我们设计了几种比较可靠而又易于掌握的取样方法,结果较为满意。
Rare earth and transition metal organic compounds, because of its anaerobic, hygroscopic, difficult to decompose and other characteristics, often make the analysis not satisfactory results. In particular, sampling technology is rarely reported, but this step is very crucial. We explored several sampling techniques and introduced them here. Weighing of liquid sample We designed a sample-like glass capillary that can be pre-filled with an oxidant in order to make the sample adsorbed evenly on the surface of the oxidant and completely decomposed (Figure 1). Second, weighed solid samples We designed several more reliable and easy to grasp the sampling method, the result is more satisfactory.
