Handheld X-ray fluorescence spectrometry (HH-XRF) has been established as the gold standard method for in-situ elemental determination in metals and alloys in the last 10 years. More than 5,000 analyzers are sold yearly worldwide for scrap metals sorting and positive material identification (PMI). PMI is a quality assurance tool consisting of the identification of alloy grades in various indust...

This paper presents the framework and results of analysis of the building materials used in traditional Chinese copper halls. The analysis of the Kunming copper hall (KCH) is presented as a typical example. First, the historical building structure of the KCH is investigated. Results of X-ray fluorescence (XRF) spectrometry are presented and analyzed according to the units of each building compo...

In mineral flotation the X-ray fluorescence (XRF) grade measurements of the slurries typically give the most important on-line information on the state of the flotation process. It has been shown that the visual and near-infrared (VNIR) reflectance spectrum measurements of certain mineral slurries can be used to complete the sparse XRF slurry content information. This study focuses on the chemo...

The aim of this research was to investigate the possibility of differentiation between black powder toners of similar polymer composition applying analytical methods: Fourier transform infrared spectrometry (FTIR) and X–ray fluorescence spectrometry (XRF). The studied materials were black powder toners of similar polymer composition sampled from the cartridges of 34 machines (31 models purchase...

Soil samples were collected from five provinces over China, including Beijing, Xinjiang, Heilongjiang, Yunnan, and Jiangsu. Heavy metal Cr, Zn, Pb and As in soils were analyzed by a portable X-ray fluorescence spectrometry (XRF). For predicating metal concentration in soils, a partial least square regression model (PLSR) was established. After cross-calibration, the correlation coefficients for...

Deposition of borophosphosilicate glass (BPSG) films as dielectrics is one of the many steps involved in semiconductor device manufacturing. Accurate control of boron and phosphorus concentrations in these films, is essential in maintaining desired film properties. The narrowing process specification limits with the industry trend towards shrinking device sizes, is putting an increasing demand ...

Micro-X-ray fluorescence and X-ray absorption fine structure (µ-XRF-XAFS) is one of the most powerful tools to identify distribution speciation trace elements in natural samples with µm spatial resolution. However, conventional µ-XRF-XAFS studies applied rare earth (REEs: lanthanide + Y this study) are mainly limited their L-edges L lines (except for Y) that subject strong interferences from ot...

A principal goal of the Mars Science Laboratory (MSL) rover Curiosity is to identify and characterize past habitable environments on Mars. Determination of the mineralogical and chemical composition of Martian rocks and soils constrains their formation and alteration pathways, providing information on climate and habitability through time. The CheMin X-ray diffraction (XRD) and X-ray fluorescen...

Fabrication of portland cements commonly depends on X-ray fluorescence (XRF), which measures the elemental compositions. XRF is used to adjust the raw material proportions and to control the process conditions. However, to predict the mechanical strength of the resulting concrete, it is essential to know the phase composition which is, so far, indirectly inferred by the Bogue method. Here, we r...

An important parameter for the distinction of X-ray flashes, X-ray rich bursts and Gamma-ray bursts in the rest frame is the distance to the explosion site. Here we report on the spectroscopic redshift determination of the host galaxy of XRF/GRB 030528 using the ESO VLT FORS2 instrument. From the strong oxygen and hydrogen emission lines the redshift was measured to be z=0.782±0.001. Obtaining ...
