“…For the selected RF power the plasma was immune to the discrete introduction of ethanol. All these results are in agreement with previous published work revealing that the plasma electron number density [34,35] and excitation temperature [36] increase in presence of ethanol.…”

A new method to carry out the elemental determination of metals in bioethanol through ICP-OES has been developed. The procedure is based on the use of a heated Torch Integrated Sample Introduction System (hTISIS) to directly introduce the vaporized sample into the plasma. Two injection modes (continuous liquid aspiration and air-segmented flow injection analysis) have been evaluated. In a first step, the matrix effects caused by several ethanol-water mixtures were removed by operating the hTISIS at 400ºC in segmented injection. Meanwhile, the results also proved that the system could be operated in continuous mode at 200ºC with the complete interferences removal. Finally, twenty-eight real samples with bioethanol contents between 55% and 100% were analyzed with the methods previously developed.Regarding validation, recoveries from 80% to 120% were obtained for 18 analytes and the concentrations found with the proposed method were in agreement with those encountered with a preconcentration method, taken as a reference procedure. Limits of detection went from 3 ng mL -1 for manganese to about 500 ng mL -1 for calcium. This allowed to quantify Cr, Fe, Mg, Mn and Zn in segmented flow injection and Al, Cd, Cr, Cu, K, Mg, Mn, Na and Zn in continuous sample aspiration mode in bioethanol samples.

“…Consequently, when an organic solvent is present in the sample, the analyte mass leaving the spray chamber per unit of time increases when compared with aqueous solutions [47] and, if the thermal characteristics of the plasma are not significantly deteriorated, higher sensitivities are obtained in ICP-AES [48].…”
