“…The comparison unveiled that also the detection limit achieved through the proposed technique outperformed that of certain plasma-based techniques. [14,44] The achieved detection limit allows the developed method to be used for the determination of arsenic at ultra-trace levels in different samples.…”

“…[9] In light of the above facts, there is a great interest in determining the arsenic concentration in environmental and drinking water samples. [10] Various analytical techniques including graphite furnace atomic absorption spectrometry (GFAAS), [11] hydride generation atomic fluorescence spectrometry (HG-AFS), [12] inductively coupled plasma-optical emission spectrometry (ICP-OES), [13] inductively coupled plasma-mass spectrometry (ICPMS), [14] electrochemical methods [15] and hydride generation-atomic absorption spectrometry (HGAAS) [16] were employed for the detection of arsenic. Among these techniques, GFAAS and ICPMS appear as attractive options.…”

A novel ultra‐sensitive gold‐coated tungsten‐coil atom trap coupled with HGAAS was developed for the first time for the determination of arsenic. The analytical methodology was based on transporting and in‐situ trapping of arsine produced by the hydride generation system onto a gold‐coated W‐coil trap for preconcentration via Ar and H2 gases. The trap surface was examined using scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. SEM images revealed that the surface is covered with hexagonal and pentagonal structures on a micro scale with gold. The experimental parameters were optimized for both trap and non‐trap method. The enhancement factor for the characteristic concentration (C0) was determined to be 15.3 when compared with the non‐trap methods. For the trapping time of 120 s using the developed method, the limit of detection (LOD) and the precision were determined as 4.8 ng L−1 and 3.6 %, respectively. The interference effects of various hydride‐forming ions were examined in detail. The accuracy of this ultrasensitive methodology was successfully verified by analysis of certified reference materials and some drinking water samples.. t‐test was implemented to the water samples, the added and measured concentrations exhibited no statistically meaningful distinction at the 95 % confidence level.

“…For the mobile phase, cationic As species are normally eluted by pyridine-based solutions [21,23,26]. For anionic As species, phosphate- [48], carbonate- [49], and nitrate-based eluents [25,41] are utilized. In this work, ammonium carbonate was used as the mobile phase buffer for anion-exchange and pyridine for cation-exchange.…”

Speciation analysis of organoarsenic species in marine samples: method optimization using fractional factorial design and method validation

et al. 2021

Organoarsenic species in marine matrices have been studied for many years but knowledge gaps still exist. Most literature focuses on monitoring of arsenic (As) species using previously published methods based on anion- and cation-exchange high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS). These studies are often limited to few As species and/or only specific method performance characteristics are described. Most marine certified reference materials (CRMs) are only certified for arsenobetaine (AB) and dimethylarsinate (DMA), making it difficult to evaluate the accuracy of analytical methods for other organoarsenic species. To address these gaps, the main objective of this work was to develop and validate a method for speciation analysis of a broad range of organoarsenic species in marine matrices. Optimum extraction conditions were identified through a 27–3 fractional factorial design using blue mussel as test sample. The effects of sample weight, type and volume of extraction solution, addition of H2O2 to the extraction solution, extraction time and temperature, and use of ultrasonication were investigated. The highest As recoveries were obtained by using 0.2 g as sample weight, 5 mL of aqueous methanol (MeOH:H2O, 50% v/v) as extractant, extraction carried out at 90 °C for 30 min, and without ultrasonication. Anion- and cation-exchange HPLC-ICP-MS settings were subsequently optimized. The method detected a total of 33 known and unknown As species within a run time of 23 and 20 min for cation-exchange and anion-exchange, respectively. A single-laboratory validation was conducted using several marine CRMs: BCR 627 (tuna fish tissue), ERM-CE278k (mussel tissue), DORM-4 (fish protein), DOLT-5 (dogfish liver), SQID-1 (cuttlefish), TORT-3 (lobster hepatopancreas), and CRM 7405-b (hijiki seaweed). Method performance characteristics were evaluated based on selectivity, limits of detection and quantification, linearity, trueness, precision, and measurement uncertainty. This work proposes an extraction procedure which allowed satisfactory quantification of As species with low solvent and energy consumption, supporting “Green Chemistry” principles. The study also presents a new set of As speciation data, including methylated arsenic species and arsenosugars, in recently issued marine CRMs, which will be valuable for future speciation studies on As. This work is the first to report a total of 33 different As species in marine CRMs. Graphical abstract

“…It should be noted that the authors assumed that DMA was the only organo-arsenic compound present. In a simplified IC-ICP-MS method 68 for the separation and detection of As III , As V and AB in ground and bottled waters, the analytes were eluted isocratically (50 mM dichloromethane. The combined extracts were dried and the residue dissolved in 1 mL of methanol:water (4+1) of which 50 µL was injected onto the column.…”
