化探中痕量银的测定

对电感耦合等离子体质谱法与一米光栅发射光谱法在化探样品中的痕量银测定进行对比,实验表明,两种方法都具有高精密度和准确度,检出限也符合区域化探的要求,但是在大批量的化探测定及多元素同时测定方面,质谱法操作简单、快速、准确、成本低,优于一米光栅发射光谱法,更适合应用于批量化探样品中银的测定。

THE DETERMINATION OF TRACE SILVER IN GEOCHEMICAL SAMPLES

Compared one meter grating emission spectrometry method with Inductively Coupled Plasma Mass Spectrometry method for determination of trace silver in geochemical samples.Experiments show that both of the method are high precision and accuracy,and the detection limits are also in line with the requirements of regional geochemical exploration.However in large quantities of probe analysis and more elements simultaneously determination,the MS method is simple,fast,accurate and lower cost,far better than one meter grating emission spectrometry,mass is more suitable for the determination of silver in geochemical samples.
