Evaluation of liquid chromatography inductively coupled plasma mass spectrometry for arsenic speciation in water from industrial treatment of shale

Determination of As(III) and total inorganic As in water samples using an on-line solid phase extraction and flow injection hydride generation atomic absorption spectrometry

“…So, five groundwater samples were analyzed for arsenic speciation by high performance liquid chromatography (HPLC) for separation and inductively coupled plasma mass spectrometry (ICPMS) for detection, employing a methodology described previously in the literature [30]. A volume of the filtered sample solution was injected in a LC system assembled with a quaternary pump (Model Series 200, PerkinElmer), a 200 L sample loop and a separation column (Dionex, IonPac AS14,250 × 4 mm i.d.)…”

Extraction and detection of organoarsenic feed additives and common arsenic species in environmental matrices by HPLC–ICP-MS

“…Consequently, the PRP-X00 column was used for separation of the organic and inorganic arsenic species in the rest of this study, and the chromatographic conditions were optimized by adjusting the composition, flow rate, and elution gradient of the mobile phase. Based on an early study [47], we first tested (NH 4 ) 2 CO 3 (10-100 mM) as the elution buffer. However, the results showed that ASA and ROX could not be eluted from the column within 30 min under the conditions listed in Table 3, due to the weak elution ability of the (NH 4 ) 2 CO 3 solution [48][49][50][51][52] (Fig.…”

Arsenic speciation in water by high-performance liquid chromatography/inductively coupled plasma mass spectrometry-method validation and uncertainty estimation

“…used a three times SD approach for LOD value calculation. Despite increasing the sample injection volume even to as high as 100 μL, or 200 μL, almost none of the authors obtained similar results to those presented by Ronkart et al . The lowest values obtained with the use of a larger sample injection volume were 0.03 µg L –1 for As(III), 0.027 µg L –1 for As(V), 0.035 µg L –1 for MMA, 0.011 µg L –1 for DMA, and 0.01 µg L –1 for AsB .…”
