Quantitative Analysis of Lead (Pb) and Arsenic (As) in Cosmetic Raw Material Powders

User Benefits

- With simple sample preparation, lead and arsenic in cosmetic raw material powder can be quantified simultaneously. - Increased X-ray tube output and optimized optical design have improved sensitivity for heavy elements. - Continuous analysis of up to 48 samples is possible, improving analysis throughput.

Introduction

The management of lead and arsenic contained in cosmetics raw materials is important for protecting people's health. Although colorimetric methods have been used for these analyses, there is a growing need for trace control due to tighter regulations in recent years, leading to a consideration of a shift to instrumental methods that enable quantification. Candidates for instrumental methods include ICP optical emission spectrometry/mass spectrometry and X-ray fluorescence spectrometry. While the former method is highly sensitive, powder and solid samples need to be dissolved in an acid such as nitric acid or hydrochloric acid. In contrast, X-ray fluorescence analysis is convenient because it can be analyzed without dissolving the sample. This application news introduces the analysis of two inorganic oxide powders (talc and titanium oxide) using the energy-dispersive X-ray fluorescence Spectrometer ALTRACE .
