“…XRF"s simplicity, its lower cost and nondestructive analyses (when compared with ICP-MS, XRF can be 5 times cheaper) [8] makes it ideal technology for rapid screening of large numbers of samples. Several studies have used this nondestructive technique for screening a wide variety of samples pertaining to public health including: flour [9], seafood [10], Indian spices and ceremonial powders [11], FDA-regulated products [8], Ayurvedic medicines [12], face powders [13] and several other food and medicinal items [14]. A comprehensive discussion of consumer product regulations for metal contaminants is beyond the scope of this paper.…”

X-ray fluorescence spectrometry (XRF) is a rapid, non-destructive multi-elemental analytical technique used for determining elemental contents ranging from percent down to the µg/g level. Although detection limits are much higher for XRF compared to other laboratory-based methods, such as inductively coupled plasma mass spectrometry (ICP-MS), ICP-optical emission spectrometry (OES) and atomic absorption spectrometry (AAS), its portability and ease of use makes it a valuable tool, especially for field-based studies. A growing necessity to monitor human exposure to toxic metals and metalloids in consumer goods, cultural products, foods and other sample types, and while performing the analysis in situ has led to several important developments in portable XRF technology. In this study, a new portable XRF analyzer based on the use of doubly curved crystal optics (HD Mobile ® ) was evaluated for detecting toxic elements in foods, medicines, cosmetics and spices used in many Asian communities. Two models of the HD Mobile ® (a pre-production and a final production unit) were investigated. Performance parameters including accuracy, precision and detection limits were characterized in a laboratory setting using certified reference materials (CRMs) and standard solutions. Bias estimates for key elements of public health significance such as As, Cd, Hg and Pb ranged from -10% to 11% for the pre-production, and -14% to 16% for the final production model. Five archived public health samples including herbal medicine products, ethnic spices and cosmetic products were analyzed using both XRF instruments. There was good agreement between the pre-production and final production models for the four key elements, such that the data were judged to be fit-for-purpose for the majority of samples analyzed. Detection of the four key elements of interest using the HD Mobile ® was confirmed using archived samples for which ICP-OES data were available based on digested sample materials. The HD Mobile ® XRF units were shown to be suitable for rapid screening of samples likely to be encountered in field based studies.

In this paper, we discuss approaches to prepare solid samples for X-ray fluorescence spectrometry (XRF). Although XRF can be used to analyze major and minor elements in various solid samples including powders and grains without dissolution techniques, to obtain reliable XRF results, the prepared sample must meet certain criteria related to homogeneity, particle size, flatness, and thickness. The conditions are defined by the analytical depth of fluorescent X-rays from analytes, and the analytical depth can be estimated from the X-ray absorption related to the energy of each X-ray and the composition and density of the sample. For example, when the sample flatness and particle size are less than the analytical depth and the sample possesses homogeneity within a depth less than the analytical depth, the XRF results are representative of the entire sample. Furthermore, an appropriate sample thickness that is larger than the analytical depth or constant can prevent changes in fluorescent X-ray intensity with variations in sample thickness. To obtain accurate and reproducible measurements, inhomogeneous solid samples must be pulverized, homogenized, and prepared as loose powder, powder pellets, or glass beads. This paper explains the approaches used to prepare solid samples for XRF analysis based on the analytical depths of fluorescent X-rays.

“…An emerging area of interest in forensics is the examination of cosmetic products. Kulikov et al employed wavelength-dispersive X-ray fl uorescence spectrometry for the elemental analysis of 39 cosmetic powders (16) . Cluster analysis and PCA were able to clearly discriminate between samples possessing traditional ingredient or mineral-based formulations, and also distinguish specifi c manufacturers of the latter.…”

Since ancient times, man has been interested in showing his appearance in the best shape and has used make-up materials including lipstick for this purpose. Four lipstick samples were selected for one brand with different colors (Lipstick-03, Lipstick-23, Lipstick-29 and Lipstick-51) as well as two different colors for the so-called magic lipstick (Luxe orang and Luxe yellow). Energy-dispersive X-ray spectroscopy (EDX) is an analytical technique was used for the elemental analysis for the selected six samples. These tests aims to explain that there are clear elemental differences for the selected samples which can be used to define the identity of each sample. Lipstick-51 has been selected to contaminate some substances that can be commonly used in homes, offices and others. The selected substances were (Plastic bottle, Plastic cup, Glass, Cigarette filter and Tissue paper). The elemental results indicate a partial match for the types of elements in lipstick contaminated with substances taken from the crime scene compared to the original Lipstick-51. Results could be more accurate when identifying the contaminated material and select the most concentrated positions for samples taken from the crime scene and for conducting tests.
