    Determination of gold concentration in geochemical samples by ICP-MS with isoamyl alcohol asa signal enhancer……Ma Yifei,Zhang Ni,Zhang Li,Quan Bin

    AbstractA method for the determination of trace gold in geochemical samples by ICP-MS with isoamyl alcohol as a signal enhancer was proposed and the conditions of the measurement were optimized.The experimental results show that under optimum conditions,2 % isoamyl alcohol can enhance the Au analysis signal strength by over 3 times,the detection limit is 0.045 ng/g,and the relative standard deviation is less than 4 %.The method has been applied to the determination of Au in geological reference materials with satisfactory results.

    Keywords:isoamyl alcohol; signal enhancement; ICP-MS; geochemical samples; trace gold
