Influence of aerosol desolvation from the ultrasonic nebulizer on the matrix effect in axial view inductively coupled plasma atomic emission spectrometry

Optimization of method for simultaneous multi-element determination of trace elements by Inductively Coupled Plasma-Optical Emission Spectrometry: Chemometric approach

“…These two competitive effects usually result in an optimum value of the carrier gas flow rate, which is then a compromise between the amounts of aerosol introduced into the plasma and the residence time of the species. In line with the literature data, it was concluded that using ultrasound nebuliser, nebulisation gas flow rate of 0.75 l/min gave satisfactory sensitivity value of analytical signals (11,15,17). The effect on the location of the maximum intensity, i.e., the viewing height where the maximum intensity could be observed, was described by Boomans (2).…”

“…ICP-OES is a powerful technique for multi-element analysis, but it can be affected by spectral interferences which limit the accuracy, repeatability and reproducibility of the method. Several methods for correction of spectral interferences have been applied (2,9,11) One of the most frequently used is the method of Interelement Correction Factor (IEC). According to this method, Eqn 3 was applied to obtain the corrected analyte concentration:…”

Simultaneous Simulations of Uptake in Plants and Leaching to Groundwater of Cadmium and Lead for Arable Land Amended with Compost or Farmyard Manure

“…An ICP-AES Iris Intrepid (Thermo Fischer Scientific Inc., Waltham, USA) and an ICP-AES Liberty Serie 2 (Varian, Mulgrave, Australia) equipped with an ultrasonic nebulizer U-5000AT+ (CETAC, Omaha, Nebraska, USA) was used for Cd and Pb analysis. Spectrometer operating conditions are fully described elsewhere [32] , [33] . Analysis quality was controlled using an in-house laboratory reference sample V463 (entire maize plant) and blanks which have undergone the entire analysis process.…”

Elemental matrix effects in ICP-AES

“…For both matrix concentrations, matrix effects were eliminated at moderate water plasma loads. 199 Conversely, the lower the gas flow rate, the stronger the matrix effects. 165 In order to understand the effect of the gas flow rate on the desolvation efficiency, it is appropriate to consider that the aerosol residence time inside the desolvation system increases as the gas flow rate goes down.…”
