Abstract

Analytical quality control in neutron activation analysis (NAA) requires the use of certified reference materials (CRM) in order to produce reliable analytical results. It is essential to evaluate the performance of NAA method when analyzing various sample matrices. Therefore, the CRM selected for an analysis should be suitable for the type of samples. There are many aspects such as concentration range, matrix match, sample size, and uncertainty, which need to be considered when selecting a suitable CRM. Eventually, results of analysis of CRM were plotted into control charts in order to evaluate the quality of the data. This is to ensure that the results are within the 95% confidence interval as stipulated in the certificate of CRM. Thus, this article aims to discuss the uses of certified reference materials for quality control purposes in NAA involving various sample matrices.

Bahan rujukan piawai adalah berguna dalam kawalan mutu analisis dalam analisis pengaktifan neutron untuk memperolehi keputusan analisis yang boleh dipercayai. Ia juga penting dalam menilai keputusan kaedah NAA semasa menganalisa pelbagai bahan sampel. Oleh yang demikian, bahan rujukan piawai yang dipilih hendaklah bersesuaian dengan jenis sample yang dikaji. Terdapat beberapa factor yang perlu dipertimbangkan semasa memilih bahan rujukan piawai seperti julat kepekatan, kesesuaian matriks, saiz sampel, dan ketidakpastian. Keputusan analisis bahan rujukan piawai diplotkan dalam carta kawalan untuk menilai kualiti data. Ini adalah untuk memastikan keputsan adalah dalam lingkungan 95% confidence interval berbanding dengan sijik bahan rujukan piawai. Kertas kerja ini bertujuan untuk membincangkan kegunaan bahan rujukan piawai dalam kawalan mutu dalam analisis pengaktifan neutron yang melibatkan pelbagai jenis sampel.
