Evaluation of a microconcentric nebuliser–cyclonic spray chamber for flow injection simultaneous multielement inductively coupled plasma optical emission spectrometry

Sample introduction systems for the analysis of liquid microsamples by ICP-AES and ICP-MS

“…Thus, for a MCN coupled to a cyclonic spray chamber, the solvent transport efficiency, ε s , at a 100 µl/min delivery liquid flow rate and a 1 l/min gas flow rate generated values close to 85% [30]. This result was different from the about 20% encountered in a different report at a 0.7 l/min gas flow rate [28].…”

“…Several reasons could be argued in order to try to explain this inconsistency. First, whereas in reference [30] an indirect method [31] was employed to measure the mass of solvent leaving the spray chamber, reference [28] used a direct method for this purpose [32]. Second, a cyclonic spray chamber was used in reference 30, whereas in reference 28 the chamber used was a double pass one.…”

AF4-UV-MALS-ICP-MS/MS, spICP-MS, and STEM-EDX for the Characterization of Metal-Containing Nanoparticles in Gas Condensates from Petroleum Hydrocarbon Samples

“…A typical nebulization efficiency in the case of nanoparticles in an aqueous suspension and a standard type of nebulizer is 2-3% 37 . However, the microconcentric nebulizers usually have a much higher efficiency, which has been reported to be between 15 and 90% depending on the nebulizer's internal diameter and the flow rate [38][39][40] . A nebulization efficiency value of 45% has been found using the operating conditions in Table S2, and the "particle size" ("RM size") method for calculation (a typical signal obtained for the 100 nm gold standard is shown in Fig.…”

Examining the analytical capabilities of a desolvating microconcent nebulizer for inductively coupled plasma-mass spectrometry

“…Because the commonly applied nebulization systems have nebulization efficiencies of just a few percent, novel nebulizer designs with higher efficiencies are of great interest to analytical chemists. Recently, microconcentric nebulizers have been introduced [1][2][3][4][5][6][7] for analysis of small sample volumes with high nebulization efficiencies. In this study, we have evaluated a new desolvating microconcentric nebulizer.…”
