Determination of Hexabromocyclododecane Diastereoisomers and Tetrabromobisphenol A in Water and Sediment by Liquid Chromatography/Mass Spectrometry

Simultaneous determination of hexabromocyclododecanes and tris (2,3-dibromopropyl) isocyanurate using LC–APCI-MS/MS

“…However, in our work, APCI showed 2-3 times higher sensitivity for HBCD than ESI, which was also confirmed by Suzuki et al, who found that APCI were approximately 2-5 times more sensitive than ESI for HBCD [25]. For TBC, both ionization sources provided almost the same sensitivity.…”

Recent Advance in Liquid Chromatography/Mass Spectrometry Techniques for Environmental Analysis in Japan

“…13) HBCDs are brominated ame retardants and are dispersed into plastics, textiles, and other polymers. e gamma HBCD isomer has the highest log P of around 8, and the recovery of this isomer by SPE was the lowest, while its recovery by LLE was 92%.…”

Recent Methodologies for Brominated Flame Retardant Determinations by Means of Liquid Chromatography–Mass Spectrometry

“…Suzuki et al [11] reported recoveries above 77% for a-, b-, and g-HBCD, after two sequential liquid-liquid extractions (LLE) with dichloromethane (DCM) of a spiked landfill leachate. However, solid-phase extraction (SPE) on Abselut Nexus cartridges was suggested as a faster alternative allowing the simultaneous determination of TBBPA (recovery 103 AE 16%) and a significant reduction in the organic solvent consumption (from 50 mL DCM to 5 mL acetone) that still provided acceptable recoveries (54-85%) of the three HBCD diastereomers.…”
