“…12 We should comment that few analytical methods are capable of traceable accuracy in this sort of application where depth sensitivity is essential: the Tutorial Review cited (ref. 11) directly compares IBA with various other methods, and a recent Critical Review 13 compares LIBS (laserinduced breakdown spectroscopy) with XRF. But LIBS, like LA-ICP-MS (laser ablation inductively-coupled plasma mass spectrometry, discussed in ref.…”

“…Despite X-ray fluorescence (XRF) is arguably a semi-quantitative technique, it was exploited for the certification of CRMs of various matrices and different levels of certified properties. Basically, the instrumentation of XRF consists of an excitation source, optical components for shaping and guiding X-ray beam to the sample and a detection device for analyzing and constructing spectrum [5]. Based on different types of their major components, various XRF techniques have been introduced.…”

Background A pilot study has being carried out at our laboratories, with international collaborators, to develop seven certified reference materials (CRMs), which have matrices of mainly soil and biological tissues. The CRMs will be certified for macro-, micro- and trace elements for environmental, toxicological, agronomic and nutritional purposes. Homogeneity of element concentrations is a critical step in the production process of CRMs. This work employs wavelength dispersive X-ray fluorescence spectrometry (WD-XRF) to test between-bottle homogeneity of the CRMs. Results The relative standard deviation (RSD), relative average deviation, Skewness and Kurtosis of element contents in seven bottles out of 80 bottles of each CRM were considered to assess homogeneity in terms of variability and distribution. More than 50% of the number of quantified elements recorded RSD between 2 and 5%. Hence, based on an in-house classification, the intended CRMs recorded excellent to good between-bottle homogeneity. Nevertheless, the contents of some elements (Ni, Rb, Zn and Br) experienced high RSD values (> 10%). The Skewness and Kurtosis values of most elements are around one indicating symmetric distribution and thus have an absence of tailing relative to the normal distribution. Conclusions WD-XRF provides fit for purpose data for assessment of initial between-bottle homogeneity in terms of rapidity, ease of use, multi-element quantification and sample non-destruction.

“…Also, LIBS and XRF can be used in conjunction with microscopy to examine microstructure and biochemistry in the same sample. LIBS and XRF are complementary methods as together, they are sensitive to elements across much of the periodic Table [ 35 ]. This combined approach has provided fast and multi-element analysis of plant nutrition [ 35 ] and our group has recently explored dental applications [ 36 ].…”

Breast feeding provides considerable benefits to the infant and mother. However, a lithium-based psychiatric medication may cause side effects in the child. Using laser induced breakdown spectroscopy (LIBS), trace lithium levels were observed in the breast milk of lactating rats administered with lithium treatment postpartum. Subsequently, the mammary glands of female rats were analyzed using LIBS, energy dispersive X-ray fluorescence spectroscopy, and inductively coupled plasma mass spectrometry. Key biological elements iron, magnesium, cobalt, calcium, phosphorus, sodium, iodine, potassium, sulfur, chlorine and zinc were observed. Lithium at 1.06 µg/g was measured in the mammary glands of treated subjects, but was below the limit of detection in controls. Lithium also increased iodine content in the glands. Lithium is present in the breast milk and mammary glands of lithium treated female subjects and this is the likely route of entry to breast-fed infants.
