地球化学样品无污染加工流程

Non-contamination Powdering Procedures for Geochemical Samples

随着科研工作者对实验数据的精度和准确度的要求越来越高,为获得可靠的地球化学样品分析数据,除将分析测试仪器条件优化外,对样品前期加工流程也给予了高度重视。笔者在大量实验的基础上,总结经验,对原有制样方法进行了改进,能够加工出小于200目无污染的粉末样品,可以满足高精度、高灵敏度及高自动化程度的测试仪器对样品的要求。

The laboratory provides the experimental methods and data for research on geochemistry,rocks and mineral resources,environment,etc.Recently the accuracy and precision of the analytical data have become increasingly required.In order to obtain reliable analytical data,in addition to optimization of analytical instruments,very much attention has been paid to the sample pre-processing procedure.On the basis of systematic experiments and accumulating experiences continually,the authors revised the previous sample powdering procedure and developed an improved new method so that 200 mesh non-contaminated powder samples can be produced,which meet the demands of the high-precision,high sensitivity and high degree of automation modern experimental instruments.
