A Complete Method for Environmental Samples by Simultaneous Axially Viewed ICP- OES following US EPA Guidelines Authors

چکیده
The Vista instrument has a number of distinct advantages over similar ICP-OES systems. Firstly, the VistaChip is the only single Charge Coupled Device (CCD) that allows full coverage of the spectrum from 165-785nm, with a pixel processing speed of 1 MHz and exceptional anti-blooming properties. These features allow both trace level analytes and major analytes to be determined in the same measurement. Secondly, the RF robustness of the Vista ICP-OES permits the analysis of difficult samples, up to 5% total dissolved solids, using an axially viewed plasma. Finally, the Cooled Cone Interface (CCI) of the axially viewed Vista eliminates the cooler tail of the plasma, reducing Easily Ionizable Element (EIE) interferences and maximizing linear dynamic range. The CCI consists of a cooled nickel cone with a large orifice at its tip, positioned to view the optimum region of the axial plasma.

Matrix effects on the determination of dysprosium, europium and ytterbium used as animal faecal markers by inductively coupled plasma optical emission spectrometry with axially- and radially- viewed configurations
Matrix effects were evaluated on the determination of Dy, Eu and Yb used as sheep faecal markers by inductively coupled plasma optical emission spectrometry (ICP-OES) with axiallyand radially-viewed configurations. The samples were prepared with microwave-assisted acid digestion using an oven with closed vessels. The analytical performances of the two ICP-OES instruments were compared using Mg ...
متن کاملIncreased Laboratory Productivity for ICP-OES Applied to U.S. EPA Method 6010C
The use of an ESI SC FAST autosampler coupled to a Perkin Elmer Optima 7300 DV ICP can dramatically improve productivity for the analysis of environmental samples using EPA SW-846 Method 6010C. Sample throughput, as determined by sample-to-sample run time can be improved by as much as 100% as compared to traditional sample introduction systems and autosampler configurations. Both sample analysi...
متن کاملAnalysis of Blood Serum on the Liberty Series II ICP OES with the Axially- Viewed Plasma
Disadvantages of flame AA are that releasing agents or modifiers are necessary and careful control of the flame stoichiometry is important to overcome chemical interferences [1]. While the atomic absorption technique offers adequate performance, in most cases it is a single element technique and is therefore slow. Analysis of Blood Serum on the Liberty Series II ICP OES with the AxiallyViewed P...
متن کاملSimultaneous determination of trace rare-earth elements in simulated water samples using ICP-OES with TODGA extraction/back-extraction
The determination of trace rare-earth elements (REEs) can be used for the assessment of environmental pollution, and is of great significance to the study of toxicity and toxicology in animals and plants. N, N, N', N'-tetraoctyl diglycolamide (TODGA) is an environmental friendly extractant that is highly selective to REEs. In this study, an analytical method was developed for the simultaneous d...
متن کاملPhosphorus Concentrations in Sequentially Fractionated Soil Samples as Affected by Digestion Methods
Sequential fractionation has helped improving our understanding of the lability and bioavailability of P in soil. Nevertheless, there have been no reports on how manipulation of the different fractions prior to analyses affects the total P (TP) concentrations measured. This study investigated the effects of sample digestion, filtration, and acidification on the TP concentrations determined by I...
