“…tend to decrease with increasing acid concentration. 27,28,37 However, different acid effects on the analyte signal are quite reasonable for many sources or processes, including the nature and concentration of the analyte or matrix, contribute to the ultimate analyte behaviors in the ICP-MS. 38 For instance, under robust ICP-MS conditions (high incident power and low nebulizer gas ow) signal enhancements do occur in inorganic acid matrixes. 28 Moreover, in low acid concentrations (<1% v/v) there is an increase in the analyte signal for HCl with a maximum intensity at $0.001% v/v HCl, but little signal changes for HNO 3 .…”

“…31 When the sample matrix is changed from H 2 O to inorganic acids, it would induce a great number of changes in aerosol properties, analyte and aerosol transport rate, and local plasma conditions, which all determine the signal intensity behavior. 38 Generally, the presence of an acid matrix can reduce solvent evaporation, as evaporation is more efficient for 0% acid (i.e. H 2 O) and the more the acid concentration the less efficient it is.…”

The influence of inorganic acids (HCl, HNO 3 , and HF) on boron isotope measurement by using multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) has been investigated. The acid concentration is in the range of 0-0.2 M. Generally, acids can enhance B signal intensities and reduce isotopic mass bias compared to that of the same B concentration in a H 2 O matrix. The signal enhancement in each acid matrix differs slightly, while B isotopic mass bias is significantly different among them, with the highest 11 B/ 10 B ratio in the HF matrix and the lowest in the HCl matrix. In HCl and HNO 3 matrices, boron isotopic mass bias reduces when the acid concentration goes up. However, such a scenario is not observed in the HF matrix. Furthermore, the 11 B/ 10 B ratio in the HF matrix is the same as that in the H 2 O matrix within the studied acid concentration (up to 0.2 M). This implies that changes in mass bias and the B signal cannot be related to the same process in ICP-MS. We suggest that B signal enhancement in inorganic acids can mainly be attributed to Coulomb fission during aerosol transport towards plasma, while boron ion redistributions in the plasma caused by matrix element (e.g. Cl, N) ionization lead to changes in isotopic mass bias. As acids can cause considerable matrix effects and mass bias for boron, acidity match between samples and standard solutions is imperative for accurate and precise B isotope measurement by MC-ICP-MS.

N2-Ar mix gas effect can easily improve the sensitivity of ICPMS; however, this effect discriminates against Sr. In this study, it was found that N2-Ar mixed gases introduced into nebulizing gas enhanced the sensitivity of online solid-phase extraction (SPE) with inductively coupled plasma mass spectrometry (ICPMS) for radioactive strontium quantification. An ultrasonic nebulizer (USN) improved the N2-Ar mixture gases effect of Sr and the mix gases (with USN) enhanced 3.7-times signal intensity of Sr in normal pure Ar gas (with USN) in an online SPE-ICPMS. By adapting the gas-loading means from nebulizing gas unit via USN, no careful tuning was necessary for the plasma turning. With this signal enhancement, a 0.06 pg/L detection limit (0.3 Bq/L) was achieved for radioactive strontium ( 90 Sr) in online SPE-ICPMS within 30 min. In addition, environmental paddle water in Fukushima NuclearPower Plant was measured and the valued correspond to that obtained by radiometry.

“…Elimination of matrix influences in practical purposes rely on different approaches like sample pretreatment, alternative introduction system, and various calibration approach as matrix matching and internal standardization. 34 Therefore, the estimated magnitude of polycarboxylic acid effects in plasma can be very useful in selection of proper analytical strategies for reliable determination of heavy elements in organic matrices.…”

Abstract. In order to establish prerequisite conditions for hyphenation of inductively coupled plasmaatomic emission spectrometry with liquid chromatography, the effects on plasma signal by loading of low concentrated solutions of tartaric, citric and dipicolinic acid were studied. The intensities of Mn, Li, Mg, Cd and Cu lines were observed in axial and radial signal collection mode. Influences of different ligand concentrations on excitation conditions compared to water were evaluated on the basis of signal-tobackground ratio (SBR) and limits of detection (LOD). Lower LOD values were established in the solutions of tartaric and citric acid than in water solution. Higher values were observed in solutions of dipicolinic acid. The Mg II / Mg I line intensity ratio was calculated in order to compare the changes in excitation conditions. Polycarboxylic acid matrices showed slightly departures from equilibrium conditions (≈3 %) in radial observation mode. The effects of polycarboxylic acids monitored on ionic and atomic lines of Cd and Cu were of more complex nature which regards to the type of compound and concentration of the acid solution.(doi: 10.5562/cca2066)
