Quantitative Analysis of Copper Alloys and Differentiation of Sample Types by Matching Function

User Benefits

- The EDXRF has a smaller footprint than the WDXRF, and does not require cooling water or other auxiliary equipment. - Analyses can be carried out simply without tedious and time-consuming sample preparation because there are few limitations on the sample shape. - Sample types can be differentiated by using the matching search function provided as a standard feature.

Introduction

Copper alloys are copper-based alloys which are produced by adding zinc, lead, tin, or other alloying elements to copper to improve machinability, wear resistance, corrosion resistance, or other properties. By composition, copper alloys are classified as the 1000 series to the 7000 series. Energy dispersive X-ray fluorescence spectrometers (EDXRF) are widely used in applications such as receiving inspections of recycled materials, taking advantage of their excellent operability and simple sample handling, but high-accuracy wavelength dispersive X-ray fluorescence spectrometers (WDXRF) are used mainly in metal manufacturing processes. However, as a result of improvement in the quantitative accuracy of EDXRF in recent years, a wider range of applications, such as use in manufacturing processes, is expected in the future. This article introduces an evaluation of the analytical performance of the Shimadzu EDX-7200 in an analysis of copper alloys, focusing on the following items. 1. Quantitative analysis by the calibration curve method (accuracy of calibration curves, lower limit of quantitation, repeatability) 2. FP (fundamental parameter) qualitative/quantitative analysis and matching function
