“…Schiller et al 154 reported a four-step column chromatographic procedure of Cr isolation prior to measurement. Results indicated that reproducibility was better than 54 Cr AE5.8 Â 10 À6 although more sample was required than during traditional TIMS analysis. The largest 52 Cr signal was monitored using a 10 10 U resistor to allow >50 V beam intensities, while a 10 12 U variant was used for the small 49 Ti and 56 Fe signals.…”

“…143 Solid-sampling fl ame AAS (HR-CS-F AAS) has a number of limitations associated with the sensitivity of determination and interference. Therefore, atomic absorption analysis of solid samples can be best done using HR-CS graphite furnace atomic absorption spectrometry (HR-CS-GF AAS) (see Refs 19,22,23,[27][28][29][43][44][45][47][48][49]58,70,73,76,77,89,101,102,108,116,126,131,132).…”

Atomic absorption spectrometry (AAS) is one of the most widely used and available methods for analysis of substances and materials. It allows one to determine about 70 elements from the periodic table and is characterized by rapidity, high accuracy and sensitivity, as well as simplicity of analytical techniques. A feature of AAS is simultaneous determination of only one element due to the use of a measurement design with a line source (hollow-cathode lamps, high-frequency electrodeless lamps, optical quantum generators, etc.). To make AAS more competitive, the fi rst commercially available continuum source atomic absorption spectrometer was designed in 2004. Unique analytical capabilities of the new instruments found application fi rst of all in the analysis of food, pharmaceuticals, waste and drinking water, oil and petrochemicals, biological objects, etc. This review covers publications on the application of continuum source AAS in analytical chemistry and provides a development outlook of the method.

“…Indeed, the SS HR-CS GFAAS has the possibility of monitoring multiple lines, improving background correction based on least-squares algorithm and integrating automatic solid sampler and microbalance, which may reduce errors caused by manual operations [10]. The SS HR-CS GFAAS has been applied in soil analysis for determination of Cd and Fe [11,12], Cd, Cr, Fe, Al [13], Se [14], Sb [15], Ag [16]. However, the literature is lacking in reports concerning the determination of Co, V, Mo and Ni in soil by SS HR-CS GFAAS.…”

New methods are proposed for the determination of Mo, Ni, Co, and V in soils using high-resolution continuum source graphite furnace atomic absorption spectrometry with direct solid sampling. Cobalt and V were simultaneously determined, and different analytical lines of Ni and V were monitored to adjust sensitivity for each sample. Accuracy was checked by means of soil certified reference materials, and also by flame atomic absorption spectrometry as comparative technique. The results for Mo, Ni, Co, and V found by proposed methods were in agreement with certified values and with those obtained by the comparative technique at 95% confidence level. The concentrations found in different soil samples were in the ranges 0.19-1.84 mg kg −1 (Mo), 9.2-22.7 mg kg −1 (Ni), 1.1-10.7 mg kg −1 (Co), and 35.6-426.1 mg kg −1 (V). The relative standard deviations were in the ranges 3.2-10% (Mo), 2.8-9.8% (Ni), 4.0-9.2% (Co), and 1.2-8.0% (V). The limits of quantification for Mo, Ni, Co, and V were 0.027, 0.071, 0.15, and 1.43 ng, respectively.
