“…The degrees of ionization of As and Se would be enhanced by electron transfer from the analyes to the carbon or carbon-containing polyatomic ions. Similar charge transfer mechanism from C + -species to analyte atoms in the central channel of the plasma discharge had been provided by Campbell et al 16 , Olivas et al 17 and Al-Ammar et al 18 . Our group 19 had demonstrated that the signal enhancement of As, Se and Te was not due to improvement in the nebulization transport of the sample by Carry-over effect experiments of volatile organic solvent.…”

Signal enhancement of elements with different ionization potential by organic solvent in inductively coupled plasma mass spectrometry was investigated. In the presence of the 3 % methanol or 4 % glycerol, the enhancement factors were in the range of 1.5 to 2.8 compared with the aqueous solution for high ionization potential elements (e.g., As, Se etc.), while the factors were less than 1.5 for the low ionization potential elements (e.g., Ce, In etc.). Signal enhancement caused by sample nebulization-transport efficiency improved was less than 1.5, which was obtained by detecting the sample aerosol collected with cold trap. The degrees of ionization of As and Se in organic solvent were increased to 69-71 and 56-58 %, respectively. However, In and Ce were only slightly increased with organic solvent. Our results demonstrated that signal enhancement of elements with high ionization potential was mainly attributed to the increased degree of ionization in plasma, while the low ionization potential elements were mainly attributed to the improved sample nebulization-transport efficiency.

“…In the first step, As and Se, due to their ionization energies close to that of carbon (i.e., 11.26 eV), would suffer from a charge transfer reaction from C ions, thus increasing the As + and Se + populations. It would explain the enhancement in the ion signals observed for these elements in ICP-MS [15,16,18,20,21]. In a second step, these ions would suffer from subsequent ion/electron recombinations thus increasing the population of the excited atoms.…”

“…Similar results have been reported by other authors [16][17][18][19]. Thus, Allain et al [16] reported a signal enhancement for Hg (600%), As (240%), Au (325%) and Se (250%) when a 36 g L − 1 carbon (as glycerol) solution was introduced into the ICP-MS. To explain these findings, some authors suggested a charge transfer mechanism between the analyte atoms and carbon positively charged ions [20,21]. The charge transfer reaction is only possible when the analyte has a similar IP as carbon, so that elements with low IP (i.e.…”

“…[20][21][22] (c) Chemical separation: it is effective, but often requires additional separation operations. 23-25 (d) Internal standard correction: it is effective to cancel the rotational matrix effect only if an internal standard is available having the same spectroscopic properties of a measurand in the measurement by ICP-MS. 26,27 (e) Isotope dilution: it could be regarded as being a special case for (c) an internal standard correction, i.e. by using an enriched isotope of the measurand as the internal standard so as to ensure an identical activity of the internal standard and the measurand.…”

The standard addition method (SAM) based on gravimetric sample preparation was investigated as an approach for the removal or cancelling of matrix effects in measurements by inductively coupled plasma mass spectrometry (ICP-MS). Deduction of the equations and experimental confirmation of the method are both given in the present work. After measuring both spiked and non-spiked samples by ICP-MS, the concentration of an element could be calculated based on the signal intensity ratio to an internal standard. A practical example was provided for the measurement of Fe in a certified reference material (CRM), i.e. NMIJ CRM 7512-a (milk powder). The validity of the method had been confirmed by the results of international comparisons with various kinds of matrix, including bioethanol, human serum, biodiesel fuel, drinking water, infant formula milk power, and seafood. The suggested method had been applied to measurements of multiple elements in three CRMs, including tap water, milk powder, and tea leave powder, respectively.
