“… Sample preparation: This is a critical step as it impacts both accuracy and precision. [ 64 ] The size and shape of the sample depends on the instrument being used. Instrument setup: Set the measurement conditions, such as known element present in the sample, elements that are absent, voltage, filters, sample mass, dimensions when possible, and measurement time. A calibration might be needed occasionally to improve sensitivity together with an element library, which is usually included with the instrument. Sample analysis: The samples is then placed in the instrument according to the sample preparation and analysis method selected.…”

X‐ray fluorescence (XRF) is a non‐destructive spectrometric technique to detect elements with an atomic number from 11 (sodium) and beyond 92 (uranium). When X‐rays or gamma rays eject tightly bound inner core electrons, an electron from an outer shell will fill the empty orbital and fluoresce. Every element has a characteristic fluorescence, which depends on the element and the electrons in the orbitals that are ejected and those that fill the orbital. With the characteristic energy of the fluorescence, we determine elemental composition and concentration when adequately calibrated. Typical run times range from a second to a few minutes with an sensitivity to as low as (ppm). XRF guns are portable devices that produce qualitative data while libraries loaded to laboratory instruments are capable of producing quantitative data. A broad range of scientists and engineers apply XRF in research—140 of the 250 scientific categories in the Web of Science (WoS) cite XRF analyses. Of the 10,000 articles indexed in WoS since 2018, chemical engineering ranks fifth with the most articles. The focus of the research in this category includes adsorption and waste water, combustion and pyrolysis, catalysis and zeolites, and nanoparticles and oxidation.

Using XRF to Analyze Metals in Felled Trees on a Suburban New York College Campus

A field sampling event was conducted to measure the concentrations of metals within the trunks of felled trees on a college campus east of New York City. Heavy metals, particularly chromium, were found present in the soils surrounding the sampled trees, allowing for a correlation coefficient to be calculated with soil and tree concentrations. A statistically significant Pearson correlation was found between these two concentrations among the samples. This study is aimed at providing researchers a starting point for their research a better understanding of local ecologies, prediction of future change, and dissemination of conservation efforts.
