摘要

The problem of finding new methods for the analysis of precious alloys has stimulated, in recent years, a number of different proposals for improving the analytical procedures introducing more robust calibration (or calibration-free) methods. In the paper "Accurate quantitative analysis of gold alloys using multi-pulse laser-induced breakdown spectroscopy and a correlation-based calibration method" by G. Galbacs, N. Jedinski, G.Cseh, Z. Galbacs and L Turi [Spectrochimica Acta Part B, Volume 63, Issue 5,591-597 (May 2008)] the authors proposed the use of multiple-pulse LIBS and a correlation-based method for building calibration curves for quantitative analysis of gold alloys. The method is proposed for gold alloys prepared using a fixed proportion of the alloying element. The general case where the relative concentration of the elements of the matrix is not a priori known is not discussed in the paper. In this communication, we will demonstrate that the method proposed is extremely fragile against matrix effects, and therefore cannot be usefully applied for the purpose of actual analytical measurements on gold alloys without a previous knowledge of the matrix composition.

Galbacs，N。Jedinski，G.Cseh，Z。Galbacs和L Turi发表的论文“使用多脉冲激光诱导击穿光谱法和基于相关的校准方法对金合金进行精确定量分析” [Spectrochimica Acta Part B，第63卷，第5,591-597期（2008年5月）]作者建议使用多脉冲LIBS和基于相关的方法建立用于金合金定量分析的校准曲线。该方法被提出用于使用固定比例的合金元素制备的金合金。本文中没有讨论矩阵元素的相对浓度不是先验已知的一般情况。在本次交流中，我们将证明所提出的方法对基质效应极为脆弱，因此，如果不事先了解基质组成，就无法有效地用于金合金的实际分析测量。
