“…Although the USN developed by Jin et al [2] can work with satisfied precision in a short period, its long-term stability is not satisfactory because the level of the test solution changes with time. And to avoid the obvious change of the test solution, the dead volume must be big enough to ensure the change of the volume is ignorable during test.…”

“…In recent years, some new techniques such as thermospray, electrospray, and various hyphenated techniques [1,2] have attracted more and more attention than the traditional nebulizers, such as pneumatic nebulizer (PN), ultrasonic nebulizer (USN), though these tra- ditional nebulizers were commercially available. In essence, the performance of the USN is excellent.…”

“…The electron density can be measured by various methods such as Doppler broadening and Stark broadening (Ref [21][22][23]. Among these methods, the electron density could be measured with reasonable accuracy by the Stark broadened line profile of an isolated atom or singly charged ion.…”

Measurements of electron temperature and electron density have been carried out on a plasma plume under very low pressure conditions (P = 1 mbar) using optical emission spectroscopy. The plasma torch was operated at a power level of 20-55 kW corresponding to an Ar/H 2 flow rate of 40/0 to 40/8 L/min and current intensity variation from 500 to 700 A. The electron temperature (T e ) was determined based on the calculation of the relative intensity of two spectral lines, H a and H b . It was found that T e decreased from 0.2 to 0.9 eV with increasing detection distance from the nozzle exit from 40 to 60 cm. Changes in the current and the flow rate of H 2 also had a significant impact on it. There are significant fluctuations in the hydrogen emission intensity when using current intensity of 700 A or with increasing hydrogen fraction in the mixture. However, it seemed that there was no evident change in T e when different powder sizes were injected. Correspondingly, electron densities ranged from 0.76 3 10 14 to 1.41 3 10 15 cm 23 and were obtained using Stark-effect broadening of the H b (486 nm) line under the assumption of local thermodynamic equilibrium (LTE).

“…Günther et al 5 used a simultaneous aerosol solution and laser-induced aerosol introduction system in combination with a drying system. A number of approaches using desolvated aerosols generated by pneumatic nebulization have been tested as alternative sample introduction systems for ICP-MS. 6 According to Hieftje et al 7 the most effective way to overcome residual spectral and matrix interference is through a more efficient solvent removal. A study to evaluate the calibration capabilities of direct liquid-ablation samples using an excimer laser for the determination of fluid inclusion in minerals was carried out by Günther et al 8 Falk et al 9 used aqueous standards as a very flexible calibration system.…”

Comparison of Laser Ablation and Dried Solution Aerosol as Sampling Systems in Inductively Coupled Plasma Mass Spectrometry

This paper describes a study designed to determine the possibility of using a dried aerosol solution for calibration in laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The relative sensitivities of tested materials mobilized by laser ablation and by aqueous nebulization were established, and the experimentally determined relative sensitivity factors (RSFs) were used in conjunction with aqueous calibration for the analysis of solid steel samples. To such a purpose a set of CRM carbon steel samples (SS-451/1 to SS-460/1) were sampled into an ICP-MS instrument by solution nebulization using a microconcentric nebulizer with membrane desolvating (D-MCN) and by laser ablation (LA). Both systems were applied with the same ICP-MS operating parameters and the analyte signals were compared. The RSF (desolvated aerosol response/ablated solid response) values were close to 1 for the analytes Cr, Ni, Co, V, and W, about 1.3 for Mo, and 1.7 for As, P, and Mn. Complementary tests were carried out using CRM SS-455/1 as a solid standard for one-point calibration, applying LAMTRACE software for data reduction and quantification. The analytical results are in good agreement with the certified values in all cases, showing that the applicability of dried aerosol solutions is a good alternative calibration system for laser ablation sampling.
