“…In our investigations [83][84][85][86][87] it was observed that silicate slurry particles did not behave as aqueous aerosols in the transport system and in the plasma. The region of maximum intensity in the plasma for slurries with a particle size of 5-10 µm was not identical to that of aqueous solutions [84].…”

“…In an effort to reduce the effect of the particle size, we employed mixed nitrogen and oxygen ICPs and extended torches, only with partial success [94]. In order to reduce the particle size, we evaluated the so-called zirconia bead and bottle method [86,87]. Notwithstanding the small and homogeneous particle size of less than 1-2 µm, quantitative results were only obtained when socalled Z-factors were applied to compensate for the difference in the intensity responses of the aqueous calibration solutions and the SRM sample slurries [86].…”

Highlights of plasma spectrochemistry in geoanalysis are reviewed. The techniques are evaluated in terms of recent instrumental developments, calibration strategies, spectral and matrix interferences and analytical performance. While acid decomposition results in solutions containing low salt contents, this decomposition strategy is inappropriate for numerous sample types due to poor recoveries. On the other hand, alkali fusions result in total decomposition, but solutions containing high salt contents constrain the accuracy due to interference effects in the inductively coupled plasma (ICP), the sample introduction system, and in the quadrupole mass spectrometer interface. Therefore, practical limits of determination are evaluated in terms of salt tolerances. It is concluded that ICP-atomic emission spectrometry (AES) is employed mainly for the accurate determination of the major and minor elements and the more abundant trace elements. On the other hand, ICP-mass spectrometry (MS) is used mainly for the determination of trace elements and together with the possibility of obtaining some isotopic information, it profoundly enhances the capability for solving geochemical problems. Several methods of direct solid sample introduction are described. These include direct current (DC) arc emission spectroscopy (DC-AES), slurry nebulization (SN), spark ablation (SA), laser ablation (LA) and glow discharges (GD). These devices allow direct solid analysis of bulk samples, single minerals and inclusions.

“…The first investigation aimed at the selection of the Al and La emission wavelengths for rationing since the use of lantanium as internal standard is mandatory to compensate for physical interference effects such as variations in the slurry-particle size, arc instability, and slurry-delivery rates [14] during the integration of the signal. For this purpose, three slurries of HR-1 Humber River Sediment containing 0.25 mg mL…”

A simple, rapid, and sensitive spectrophotometric method for the trace level determination of beryllium based on the formation of a 1:2 complex with anthralin (1,8-dihydroxyanthrone) as a new reagent is developed. A spectrophotometric method was used to determine the acidity constant and stepwise proton dissociation of the reagent. The experimental conditions for determining beryllium including the influences of pH, reagent concentration and time were evaluated and optimized. Under the optimum experimental conditions, the molar absorptivity of the complex is 0.47 × 10 4 l mol -1 cm -1 at 545 nm. Calibration graph was linear in the range of 0.04-1.04 μg ml -1 with a detection limit of 0.012 μg ml -1 and a %RSD of 0.43%, for 5 replicate determinations at 0.48 μg ml -1 of Be( ). The interferring effect of some cations and anions was also studied. The method was applied for the determination of beryllium in beryl, silicate rock and alloys. Ethylenediaminetetraacetic acid (EDTA) was used for masking interfering ions.
