“…Despite notable efforts toward the improvement of sample introduction methods for HPLC-ICP-AES (9)(10)(11)(12)(13)(14)(15)(16)(17), no dramatic improvements have been reported. Browner and Boom (18) have best summarized the present situation: "... the future growth of "speciation" measurement using atomic spectroscopy may be curtailed.…”

“…Effect of Injector Gas Flow Rate on Transport Efficiency and Mass Transport Rate. The data presented in the previous section were obtained at an injector gas flow of 1 L/min, the rate typically used for Ar and He ICP discharges (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). Figure 4 presents the effect of the injector gas flow on transport efficiency and mass transport rate measured at the outlet of the spray chamber for IPTGFN, EPCGFN, and DGFN with Ar and He as injector gases.…”

“…Thus far, the pore size of all effective frit-type nebulizers has been in the range of 4-10 µ (4)(5)(6)(7)(8)(9)(10)(11)(12). A pore size of 1-1.6 µ was used for the thimble glass frit to increase the velocity of gas through the pores, thereby producing a more efficient nebulizer.…”

A thimble-shaped glass frit nebulizer has been developed for atomic spectrometry. The thimble glass frit was pressurized internally by gases such as helium (He) or argon (Ar) while the test solution was applied externally to the frit. The pressurized gas exited through the pores of the glass frit and shattered the thin liquid film flowing on the surface of the thimble-shaped device to form small droplets. A small spray chamber surrounded the nebulizer to remove the large droplets. Small droplets were then introduced into inductively coupled plasmas (ICP) sustained in either Ar or He. To reduce the memory effect noted in the frit-type nebulizers, a clean-out system was also devised. Detection limits, signal-to-background ratios (S/B), precision, memory effects, noise power spectra (NPS), and particle size distributions measured with the new nebulizer were compared to those of disk and cylindrical glass frit nebulizers and the commonly used pneumatic nebulizer for Ar ICP atomic emission spectrometry (AES). Analytical performance was also measured for He ICP by using frit-type nebulizers and an ultrasonic nebulizer.

International audienceThe aim of this study was to evaluate nebulization devices and spray chambers used to couple ion chromatography with ICP-OES. In this prospect, the chromatographic performances for the separation of Cr(III), Cd(II), Ga(III) and Fe(III) were compared for all the nebulizers and chambers tested. In fact, the choice of a suitable interfacing device is mainly dictated by its sensitivity. However, this study shows that chromatographic efficiency could also be important. The results indicate that the difference in volume between the conventional and miniaturized cyclonic chambers is not critical with respect to extra-column band broadening for the case of classical columns. So, the conventional chamber, which presented the highest sensitivities and limits of detection, was selected. However, the study of five nebulizers, a conventional pneumatic concentric nebulizer and four micronebulizers, showed that they influenced the number of theoretical plates more. The Aspire micronebulizer presented the highest sensitivities, detection limits and chromatographic efficiencies and was recommended for microchromatography. However, the pneumatic concentric nebulizer exhibited better performances at 1 mL min–1
