Compensation of inorganic acid interferences in ICP-OES and ICP-MS using a Flow Blurring® multinebulizer

Abstract

17A new and easy method has been proposed for compensation of inorganic acid matrix techniques. 25The applicability of the proposed method has been evaluated analyzing two whole milk 28Compared with other calibration strategies and experimental setups used, the on-line 29 standard addition calibration using the FBMN-based system is faster, easier to handle 30 and significantly reduces reagents and sample consumption.

Multiple-channel Concentric Grid Nebulizer for Online Standard Addition in Inductively Coupled Plasma Optical Emission Spectrometry

“…Advance Publication by J-STAGE Received October 15, 2019; Accepted December 17, 2019; Published online on December 27, 2019 DOI: 10.2116/analsci.19P385 been developed using (i) two nebulizers with one or two spray chamber, [7][8][9][10] (ii) multiplenozzle nebulizer, [11][12][13][14] (iii) cross-flow nebulizer having multiple liquid channels. [15][16][17] Above all systems can simultaneously introduce sample and standard solutions into the plasma without pre-mixing, but have other drawbacks for sensitivity, reproducibility, and/or handling.…”

“…In addition, each nebulizer or nozzle independently works, resulting in the variances of the loading amounts of two liquids into the plasma. High performance nebulizers such as high efficiency nebulizer (HEN), 9 flow blurring nebulizer (FBN) 10 , and multi-spray type FBN, [11][12][13][14] which can generate finer aerosols than conventional nebulizers, was applied to improve the performance of the type (i) and (ii) systems.…”

“…Online standard addition with a T-pipe mixing has been investigated, [4][5][6] and alternative systems using a multi-nebulizing unit has been developed for improving an efficiency of an online standard addition. [7][8][9][10][11][12][13][14][15][16][17] Several multi-nebulizing systems have…”

Vortex-assisted dispersive liquid–liquid microextraction for the determination of molybdenum in plants by inductively coupled plasma optical emission spectrometry

“…Table 2 shows the figures of merit obtained for the factor was calculated as the ratio of sensitivities obtained with and without DLLME 21 procedure. The high enhancement factor achieved is due to the fact that the organic 22 extract was introduced into the plasma without an additional dilution step as needed in 23 several procedures previously described in the literature 5,10,16 . However, it is important 24 to highlight that the organic extract is diluted in the aerosol phase inside the spray 1 chamber, since the HNO 3 solution is continuously introduced.…”

“…It is also important to 16 mention that during the whole discrete injection procedure the continuous nebulization of the HNO 3 solution was necessary to clean the spray chamber, and also helped to 1 prevent the deposition of carbon residues on the quartz torch. Thus, the integrated area of the first peak was not considered for any calculation in this 22 work, and all calculations were based on the 5 subsequent peaks (n = 5).…”
