“…32 In addition, even considering a better sensitivity for this species, 138 Ba 19 F + (m/z 157) is still susceptible to polyatomic and isobaric interferences, such as from 157 Gd + and 138 Ba 18 O 1 H + , and is also highly matrix dependent. 35,36 Therefore, it is still necessary to perform a mass-shift approach in order to guarantee BaF + determination free of spectral interferences by ICP-MS. 32,34,37 With this objective, both NH 3 25 and O As an alternative strategy for fluorine determination by ICP-MS, a method using a quadrupole instrument operating in negative mode has been developed. 35,36 By making some adjustments to the nebulizer gas flow rate (0.60-0.70 L min −1 ), fluorine determination was performed in standard solution and the LOD was 400 ng mL −1 .…”

Rationale In this review, works published in the past 25 years for fluorine, chlorine, bromine, and iodine determination in several matrices by inductively coupled plasma mass spectrometry (ICP‐MS) were covered. Usually, the determination of halogens has been performed by ICP‐MS using a previous sample preparation step or, more recently, by direct analysis of solid or liquid samples. Methods Methods based on combustion, extraction, pyrohydrolysis, sample dilution in organic or aqueous medium, and wet digestion, among others, are discussed. Moreover, the recent applications of methods based on laser ablation (LA) and electrothermal vaporization (ETV) coupled to ICP‐MS are discussed. Results The main challenge for methods using sample preparation has been to obtain a final solution compatible with ICP‐MS, as well as to overcome problems related to analyte losses and contamination. Interferences due to the presence of dissolved organic compounds in solution, enhancement or suppression of ionization of analytes, and related matrix effects have been of concern when using ICP‐MS. For the determination of halogens by ICP‐MS using LA and ETV systems, some limitations related to the difficulty of calibration are pointed out, impairing the widespread use of this approach. Conclusions A critical view is presented for further halogen determination by ICP‐MS, mainly for matrices considered difficult to digest using conventional protocols.

Classification of chemical elements in the reaction cell of an inductively coupled plasma mass spectrometer (ICP-MS) was first reported based on the affinities with multiple elements, i.e. sulfur, oxygen, and fluorine. The data were summarized in the periodic table based on the affinity with each of the three elements mentioned above. An example of the application of the present results was illustrated by analyzing Y and La in the matrix of Sr and Ba, offering apparently improved background equivalent concentration (BEC) and detection limits (DL). Keywords: Classification | Chemical element | Reaction cellSeparation of spectral interferences is one of the key issues for elemental measurement by using an inductively coupled plasma mass spectrometer (ICP-MS), which is a well-developed instrument capable of simultaneous measurement of multiple elements in a wide linearity range up to nine orders of magnitude. Reaction cell technique offers an effective approach for the separation of spectral interferences in the measurement by ICP-MS. 15 In order to achieve specific separations of various spectral interferences, some kinds of gases had been explored as the reaction gas in the reaction cell of ICP-MS, including H 2 , O 2 , NH 3 , CH 3 F, N 2 H 6 , N 2 O, CO, NO, and SF 6 .5 A systematic investigation of the ion-molecule reactions in the reaction cell will provide useful information for the development of a method for separating spectral interferences. However, it was difficult to elucidate the ion-molecule reactions by using a traditional ICP-MS instrument with a single quadrupole mass spectrometer (QMS) since the ionic species entering the reaction cell were extremely complicated, including polyatomic ions from the matrix of the sample, the solvent, the argon plasma gas, and the constituents of air.Detailed work on multiple elements in the periodic table had been carried out regarding the reactions with oxygen and fluoromethane, respectively, based on laboratory-developed selected ion flow tube (SIFT) ICP-MS. 68 In these studies, both atom attachment and molecule attachment have been observed with oxygen and fluoromethane, respectively, as the reaction cell gas. High-order reactions with attachment of multiple molecules had also been observed for some elements. Such kinds of information benefit the built up of spectral separation strategies in ICP-MS measurement. It is notable that SIFT-ICP-MS was developed in the Bohme group and was not commercially available for common ICP-MS users.In recent years, the commercial availability of ICP-QMS/ QMS, i.e. ICP-MS with a pair of QMS and an octapole reaction cell (ORC), makes it possible to investigate in detail ionmolecule reactions in the reaction cell by common ICP-MS users. The first QMS (QMS1) of the ICP-QMS/QMS instrument permits the ions with selected mass-to-charge (m/z) ratio to enter the ORC and to react with the reaction gas molecules so as to exclude the interferences from ionic species with unwanted m/z ratios, which were problematic when a traditional ICP-MS...
