A high‐resolution X‐ray fluorescence spectrometer and its application at SSRF

10-Sep-2013 | Xing Gao, Songqi Gu, Qian Gao, Yang Zou, Zheng Jiang, Shuo Zhang, Xiangjun Wei, Haisheng Yu, Guodong Sheng, Peiquan ..., X-Ray Spectrometry, 2013

A high‐resolution X‐ray fluorescence spectrometer based on Rowland circle geometry was developed and installed at BL14W1 XAFS beamline of Shanghai Synchrotron Radiation Facility. The spectrometer mainly consists of three parts: a sample holder, a spherically curved Si crystal, and an avalanche ...

In‐situ spectroscopic assessment of the conservation state of building materials from a Palace house affected by infiltration water

28-Aug-2013 | Olivia Gómez‐Laserna, María Ángeles Olazabal, Héctor Morillas, Nagore Prieto‐Taboada, Irantzu Martinez‐Arkarazo, Gor ..., Journal of Raman Spectroscopy, 2013

The built Heritage constantly suffers different deterioration processes caused by the action of external agents, being one of the main consequences of the formation of soluble salts. These salts appear as efflorescences or subefflorescences that by hydration and dehydration cycles and/or ...

Theoretical and experimental study on the angular dependence of scattering processes in X‐ray fluorescence systems

23-May-2013 | M. Guerra, M. Manso, S. Pessanha, S. Longelin, M. L. Carvalho, X-Ray Spectrometry, 2013

The role of X‐ray reflectivity, coherent, and incoherent scattering has been studied in light samples. The angular dependence of these processes was evaluated, and the best geometrical settings for X‐ray fluorescence spectrometers was studied both for symmetrical and asymmetrical setups. ...

On the elemental composition of PM2.5 in central Cairo, Egypt

10-May-2013 | Johan Boman, Abdallah A. Shaltout, Asmaa M. Abozied, Salwa K. Hassan, X-Ray Spectrometry, 2013

Aerosol particles are among the criteria pollutants identified by many countries because of their effects on human health and the environment. Information about the elemental composition of the aerosol particles is useful for source apportionment and determining the possible negative effects of ...

Trace elemental determination by portable total reflection X‐ray fluorescence spectrometer with low wattage X‐ray tube

21-Feb-2013 | Shinsuke Kunimura, Jun Kawai, X-Ray Spectrometry, 2013

A specimen containing nanograms of Sb, rare earth elements, Pb, and Bi and a specimen containing a few nanograms each of As and Pb were measured using a portable total reflection X‐ray fluorescence spectrometer. Nanograms of Sb, rare earth elements, Pb, and Bi were detected. Although the As Kα ...

On‐site Raman and XRF analysis of Japanese/Chinese bronze/brass patina – the search for specific Raman signatures

11-Nov-2011 | Colomban, Philippe; Tournié, Aurélie; Maucuer, Michel; Meynard, Philippe, Journal of Raman Spectroscopy, 2011

The assignment of Asian bronzes and brasses is difficult because the copies of ancient pieces have been made a long time ago in different countries. A selection of 30 Japanese and/or Chinese bronzes/brasses are studied on‐site in the storage and exhibition rooms of the Cernuschi Museum, in ...

Characterization of some ancient glass vessels fragments found in Xinjiang, China, using a portable energy dispersive XRF spectrometer

01-Sep-2011 | Liu, Song; Li, Qinghui; Gan, Fuxi; Zhang, Ping, X-Ray Spectrometry, 2011

Abstract In this article, a portable energy dispersive X‐ray fluorescence spectrometer having determination capability for elements of Na and Mg is applied to characterization of the 58 ancient glass vessels fragments found in Xinjiang, China, successfully. These ancient glass samples were ...

Effect of primary filter using theoretical intensity of fluorescent X‐rays and scattered X‐rays

01-Nov-2010 | Ogawa, R.; Ochi, H.; Nishino, M.; Ichimaru, N.; Yamato, R., X-Ray Spectrometry, 2010

Abstract A primary filter is often used for low‐concentration analysis by energy‐dispersive X‐ray fluorescence spectrometer. We determined the material and thickness of the primary filter and calculated the theoretical intensities of the fluorescent X‐rays and scattered X‐rays using lead in ...
