Determination of impurities in titanium nitride by slurry introduction axial viewed inductively coupled plasma optical emission spectrometry

Abstract

A method of slurry nebulization for inductively coupled plasma optical emission spectrometry (ICP-OES) applied to the analysis of titanium niride(TiN) was reported. The TiN slurry sample was prepared with adding dispersant polyacrylate amine or polyethylene imine for the stabilization and homogenization of suspension, and the amount of additives was optimized. A Babington type cross-flow nebulizer with V-groove was used for nebulization of the slurry for avoidance of blockage from the particles. The stability of slurry was characterized via zeta potential measurement, scanning electron microscope observation, particle size distrbution measurement and signal stability testing. For nm size TiN, calibration curves could be established by aqueous standards and the analytical results were in good accordance with the alkaline fusion method. For Am size TiN, a negative deviation was observed for most of elements and this deviation can be corrected by using Ti intrinsic internal standard method. D

Inductively coupled plasma optical emission spectrometry with axially viewed configuration: an overview of applications

“…Some publications proposed the use of increasing masses of certified reference materials for the calibration, [25][26][27] but aqueous solutions could also be used. 27,[31][32][33] The use of the generalized standard additions method (GSAM), an expansion of the conventional standard additions method, has also been proposed for slurry analysis in a dual view 28 and in an axially viewed ICP OES. 29 In a simplified way, it is based on the idea that both quantities of reference solution and sample mass are changed.…”

Slurry nebulization in plasmas for analysis of advanced ceramic materials

“…A puck-type grinder reduces the particle size through the action of a spinning puck and a ring inside a grinding container. 24,25 The grinding container may be made with materials resistant to abrasion, e.g., hardened steel, tungsten carbide, agate, or alumina ceramic. Alumina ceramic is in particular resistant to abrasion and lightweight, as it is almost pure aluminium oxide with trace amounts of silicon, calcium, and magnesium, although it is brittle.…”

Slurry Sampling—An Analytical Strategy for the Determination of Metals and Metalloids by Spectroanalytical Techniques

“…In ICP-based techniques the upper limit in particle size depends primarily on the type of nebulizer. V-groove Babington-type nebulizers are the most popular for use in slurry sampling and have been applied to detection by ICP-OES and ICP-MS (40,41). For systems coupling electrothermal vaporization (ETV) with ICP-based detection the effect of particle size is identical to that described for ET-AAS.…”
