Introduction

DW-NP-5010A energy dispersive XRF has very wide application. It can do qualitative, quantitative and no sample analysis. Such as block sample, powder or liquid samples, from the 4th element in the periodic table beryllium (Be) to the 92rd element uranium (U), almost all of the elements can be accurately analyzed. The analytical concentration range can be from 0.1 PPM to 100%, and even up to 100% of the elementconcentration can be directly measured without dilution.XRF analysis method has the advantages of simple sample preparation, wide determination range of elements, high determination accuracy, good reproducibility, fast measurement speed (30s-900s), no environmental pollution and no destruction of samples.
