Just Published: Spectrochimica Acta Part B: Atomic Spectroscopy

A new issue of this journal has just been published. To see abstracts of the papers it contains (with links through to the full papers) click here:
Spectrochimica Acta Part B: Atomic Spectroscopy
Selected papers from the latest issue:



► We review development of the LIBS technique for trace analysis of light elements. ► This includes recent advances in laser pulse structure and industrial LIBS systems. ► Detection of light elements by LIBS in the optical region is still difficult. ► LIBS combination with either DLIFS or DLAAS would represent a potential solution.

  Regular Papers



► Deposition of urine on clinical filters facilitates home-based collection schemes. ►SS HR CS GFAAS enables direct determination of Mo and Ti in urine dried spots. ► These elements may be used as biomarkers to detect prosthesis malfunctioning. ► The way in which the sample is deposited in the filter is a key to proper quantitation. ► The use of matrix-matched urine standards for calibration is recommended.

Production of metastable 23S1 helium in a laser produced plasma at low pressures   Original Research Article

Pages 20-25
M. Bišćan, S. Milošević


► Production and decay of 23S1metastable He upon laser ablation were studied. ► Various targets in the regime of low helium gas pressures were used. ► CRDS was employed for lineshape measurements of the He 388.8nm transition. ► At larger fluences highest yield of metastables was obtained for aluminum target.

Spectroscopic characterization of atmospheric pressure argon plasmas sustained with the Torche à Injection Axiale sur Guide d'Ondes   Original Research Article

Pages 26-35
R. Rincón, J. Muñoz, M. Sáez, M.D. Calzada


► Ar discharges generated with microwave TIAGO torch were studied by OES. ► Great influence of atmosphere surrounding the flame on discharge parameters ► Electron densities ranging from 1014cm−3to 1015cm−3depending on argon flow rate ► Gas temperatures ranging from 2500K to 6000K depending on gas flow rate ► Small impact of input power on electron density and gas temperature

The influence of the sample introduction system on signals of different tin compounds in inductively coupled plasma-based techniques   Original Research Article

Pages 36-42
Javier Montiel, Guillermo Grindlay, Luis Gras, Margaretha T.C. de Loos-Vollebregt, Juan Mora


► Tin ICP-based signals depend on the compound chemical form. ► Signal differences are related to the compound volatility. ► Signal differences are reduced using high efficient sample introduction systems.

Laser ablation methods for analysis of urinary calculi: Comparison study based on calibration pellets   Original Research Article

Pages 43-49
K. Štěpánková, K. Novotný, M. Vašinová Galiová, V. Kanický, J. Kaiser, D.W. Hahn


► In this study we compare several laser-ablation based analytical techniques. ► The aim is to prove the calibration capabilities and limitations of these methods. ► Calibration pellets were prepared from human urinary calculi. ► Simultaneous LIBS–LA-ICP-OES, LA-ICP-MS and LA-LIBS were utilized.

Backscattered electron images, X-ray maps and Monte Carlo simulations applied to the study of plagioclase composition in volcanic rocks   Original Research Article

Pages 50-58
V. Galván Josa, D. Fracchia, G. Castellano, E. Crespo, A. Kang, R. Bonetto


► High resolution maps of anorthite content in single plagioclase crystals were obtained. ► The procedure was tested on volcanic rocks and is suitable for more evolved plagioclases. ► The ultimate resolution of X-rays and BE signal were studied by Monte Carlo simulations. ► MC simulations allowed to explain the BE contrast enhancement due to interface crossing.

  Technical Note



► The fluorescence enhancement correction factor in EPMA is studied. ► Reed's correction formulae were modified to account for Kβ and Kα lines separately. ► The differences evidenced encourage the implementation of completeFcorrections. ► Trace elemental concentrations may demand complete assessment of fluorescence factor.

  Analytical Note



► A new method for the determination of boron isotope ratios by ICP-OES is proposed. ► It is based on the isotopic shift of10B and11B in the emission line of 208.957nm. ► MCR-ALS was used for the resolution of the atomic emission spectra of boron isotopes. ► The proposed method presents good statistical parameters.
