Use of Ultrasonic Nebulization with ICP‐AES for Enhanced Detection of Regulated Elements in Toys
23 Apr 2015This application note will examine the use of an efficient ultrasonic nebulizer (USN) with axial‐viewing ICP‐AES for enhanced detection of the elements in toys. Experimental parameters include ultrasonic nebulizer installation steps to the host ICP‐AES instrument, sample preparation in dilute hydrochloric acid, reagent addition for improved measurement of boron (D‐mannitol) and mercury (L‐cysteine), and optimization of ICP‐AES power and gas flows when using the USN. Figures of merit will include instrument detection and quantitation limits and measured concentrations of regulated elements from a variety of toy samples.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
