A simple method for glass analysis using total reflection X-ray fluorescence spectrometry

Forensic glass examinations—A review focused on elemental spectrochemical analysis

“…The analytical performance of the method was comparable to ICP‐MS, with the added advantage of minimal sample preparation and not requiring calibration. Some additional benefits of TXRF are negligible matrix and no memory effect, fast and simultaneous multi‐elemental analysis with limits of detection for the elements of interest on glass ranging from 0.3 to 8 ppm (Costa et al, 2022).…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…A simple TXRF method of glass analysis that was capable of multi-elemental analysis, that consumed low amounts of reagents and did not require a calibration curve was presented by Costa et al 164 These authors used central composite design (a statistical method often used to optimize parameters) to optimize the sample grinding procedure, with optimal values being 1 g of sample, grinding in a ball mill for 6 min and at an impact frequency of 23 Hz. Once the optimal parameters had been established, 10 mg of ground sample was placed in a tube and 990 μL of aqueous 1.0% v/v Triton X-114 solution added.…”

Interpol review of paint, tape, and glass evidence 2019–2022

“…Costa et al [ 173 ] report the use of total reflection X-ray fluorescence (TXRF) for the analysis of Na, Mg, Al, K, Ca, Ti, V, Cr, Mn, Ni, Cu, Zn, Rb, Sr, Ba and Pb concentrations in glass samples. The authors report that the limit of detection (LOD) and limit of quantification (LOQ) were “adequate” for determination of trace elements in glass.…”
