贵金属分析仪在合质金检测中的应用

Application of Precious Metal Analyzer in Synthetic Gold Detection

合质金使用火试金法测定前,需要先进行预测定,使用常规的重量法进行预测定,耗费时间长、成本高,且只能预测定出其中金和银含量,无法得到能影响检测结果的铜、铂、钯、铼、钨等元素的检测结果。使用贵金属分析仪对合质金进行预测定,可快速测定出合质金中的金、银及杂质元素含量,根据预测定结果对样品进行预处理,确保杂质元素不对检测结果产生影响。该种预测定方式检测成本低、耗费的时间短,适合应用于合质金中金含量的预测定过程中。

Before the determination of crude gold by fire assay method,it is necessary to make predictions,and the use of conventional gravimetric methods for predictions is time-consuming,costly,and can only predict the gold and silver content,and can not get the test results of copper,platinum,palladium,rhenium,tungsten and other elements that can affect the test results.Using a precious metal analyzer to predict crude gold,the content of gold,silver and impurity elements in crude gold can be quickly determined,and the sample is pretreated according to the prediction results to ensure that the impurity elements do not affect the test results.This predictive method has low detection cost and short time,and is suitable for the prediction of gold content in crude gold.
