چکیده
High pressure inductively coupled plasma (ICP) sources are used in numerous applications, in particular for the testing of thermal protection materials used to protect space (re-)entry vehicles. The planetary gas is injected in a swirling, annular way into a heat-resistant quartz tube, surrounded by an inductor. A radio-frequency electric current runs through the inductor and induces a secondary current through the gas inside the tube, which heats up by means of Ohmic dissipation. Such an ICP torch (Fig. 1) typically produces a low

Determination of 137Ba Isotope Abundances in Water Samples by Inductively Coupled Plasma-optical Emission Spectrometry Combined with Least-squares Support Vector Machine Regression
A simple and rapid method for the determination of 137Ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) coupled with least-squares support vector machine regression (LS-SVM) is reported. By evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination...
متن کاملSelective Separation and Preconcentration of trace Amounts of Gallium in Water and Rice Samples using Cloud Point Extraction and Determination by Inductively Coupled Plasma-Atomic Emission Spectrometry
In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...

متن کامل3-D Numerical Investigation of Flow Field in Starting Stage of High Speed Wind Tunnels
High speed wind tunnels are widely used in the study of fluid flow behavior around various objects. The air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. To arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. ...
