Novel non-target analysis of fluorine compounds using ICPMS/MS and HPLC-ICPMS/MS

Abstract

The first study which shows that total fluorine determination and fluorine speciation analysis are possible with a conventional ICPMS/MS by creating BaF+ions in the plasma and limiting the polyatomic interfering barium oxide/hydroxide ions at a ppb level.

Analysis of Fluorine in Drinking Water by ICP-QMS/QMS with an Octupole Reaction Cell

“…It can be seen in Table 2 that the sensitivity, the BEC, and the LDL for the present work were not as good as, but were generally comparable to, those obtained by Yamada, Jamari et al, and Guo et al [11][12][13] Such difference might be partly attributed to the instrument-to-instrument variation. Nevertheless, the BEC and the LDL obtained in the present work were low enough for the analysis of drinking water regarding to the WHO recommended guideline value for fluorine, i.e.…”

“…Two applications had been reported with high-pressure liquid chromatography (HPLC) and extraction techniques. 12,13 In the present experiment, this technique was further investigated in detail and applied to the analysis of tap-water samples, covering optimization of the radio frequency (RF) power to improve the production of BaF + species in the plasma, optimization of the reaction cell gas flow rate for effective removal of spectral interferences, dependence of the BaF + signal intensities on the concentration of the Ba concentration, matrix effect of cations and anions on the sensitivity of measurement, and so on. It is notable that the matrix effect might be a serious issue affecting the accuracy of the results, taking into consideration the fact that the measurement of fluorine was carried out by monitoring a polyatomic ion.…”

Challenges and trends for halogen determination by inductively coupled plasma mass spectrometry: A review

“…22,25 However, as for other similar cases, 25,31,32 if a molecular ion containing fluorine (MF) + , with high dissociation energy and low first and second ionization energies can be formed in the plasma, inductively coupled plasma mass spectrometry with a triple quadrupole instrument (ICP-QQQ) can be used to minimize interferences. 25,31,32 In this sense, the addition of Ba to form a 138 Ba 19 F + ion in the plasma has been evaluated in some studies (as BaF + has first and second ionization energies of 5.21 and 10 eV, respectively, and a relatively high dissociation energy of 6.39 eV). [31][32][33] As an example, fluorine was determined in water by monitoring the signal of 138 Ba 19 F at m/z 157 using ICP-QQQ.…”

Product ions such as 16 O 2 + (m/z 32), 138 Ba + (m/z 138), 138 spectra from the m/z 157 precursor ion and their intensities were independent of the fluorine concentration added.…”
