“…Other methods used hydride generation coupled with ICP—triple quadrupole bypassed the chromatographic separation with very good results in terms of recoveries [ 44 ]. A very interesting procedure was developed by coupling laser ablation with the ICP-MS (LA-ICP-MS) for direct measurement in solid samples of inorganic arsenic species previously separated by thin layer chromatography [ 45 ].…”

Arsenic is a well-known carcinogenic, mutagenic and toxic element and occurs in the environment both as inorganic arsenic (iAs) and organoarsenical compounds (oAsCs). Since the toxicity of arsenic compounds depends on their chemical form, the identification and determination of arsenic species are essential. Recently, the European Food Safety Authority, following the European Commission request, published a report on chronic dietary exposure to iAs and recommended the development and validation of analytical methods with adequate sensitivity and refined extraction procedures for this determination. Moreover, the authority called upon new arsenic speciation data for complex food matrices such as seaweeds, grains and grain-based products. Looking at this context, an optimized, sensitive and fast analytical method using high performance liquid chromatography followed by inductively coupled plasma—mass spectrometry (HPLC/ICP-MS) was developed for the determination of iAs (sum of arsenite—AsIII and arsenate—AsV) and the most relevant oAsCs, arsenobetaine, dimethylarsinic acid and monomethylarsonic acid. The method was validated with satisfactory results in terms of linearity, sensitivity, selectivity, precision, recovery, uncertainty, ruggedness and matrix effect, and then successfully applied for the analysis of several matrices, i.e., processed and unprocessed cereal and cereal products, fruits, vegetables, legumes, seaweeds, nuts and seeds. The results obtained indicate that not only seaweed and rice matrices but also many cereals, legumes and plant-based foods for infants and young children contain significant concentrations of iAs and oAsCs. These findings contribute to the data collection necessary to assess the role of these matrices in the total arsenic exposure and if specific maximum limits have to be established.

“…The application of μ-TLC for the speciation of iAs in aqueous media by LA-ICP-MS has also been reported. 34 An As V imprinted polymer was synthesised by copolymerisation of itaconic acid and ethylene glycol di-methacrylate in the presence of As V in acetonitrile assisted by ultrasound. The method used a TLC plate fabricated with the As V imprinted polymer nanoparticles.…”

“…column set at 40 C using a mobile phase of (A) 0.1% TFA in water and (B) 0.1% TFA in AcN under gradient elution. The eluent was mixed with either 77 Se or 34 S via a static mixing piece and introduced directly into the nebuliser or the ICP-MS/MS, operated with O 2 as a reaction gas, to detect 32 S 16 O, 34 S 16 O, 77 Se 16 O and 80 Se 16 O. The analytical performance of postcolumn IDA was compared with external calibration based on matrix-matched standards.…”

“…Reasonable extraction efficiencies with relatively low interspecies transformation rates were considered possible if the ultrasonic bath conditions were 150–300 W and 40–60 °C with a 5–10 min extraction time. To separate As III from As V in Iranian mine waters, an As V -specific IIP was prepared 64 and applied to an etched TLC plate to form a set of μTLC plates for subsequent LA-ICP-MS detection. Optimum separation for a 10 μL sample volume was obtained within 10 min with a 1 : 1 acetonitrile : water mobile phase.…”

“…It was claimed that these three RMs are the rst with absolute Mo isotope amount ratios traceable to SI units. Another contribution 222 described the development, uncertainty evaluation and certication of a set of eleven new Zn isotope RMs (GBW04465-04475) with 64 Zn/ 66 Zn ratios ranging from 0.02 to 13. They were gravimetrically prepared from enriched isotopic materials whose composition had been accurately determined by total evaporation TIMS.…”
