The collected volatile compounds were analysed by GC-MS using a HBr-methanol-treated capillary column. Two ion sources were used for this study and their performance characteristics compared. These were electron impact (EI) and negative chemical ionisation (NCI), which allowed both detection of trace amounts of analytes (NCI source) and their identification. This approach provides structural information on the sampled species; at this stage no quantitation was attempted. TBTCl can be detected in the vapour phase above saline water or PACS 2 sediment after one night of passive sampling without any stirring or heating of the sample. This work indicates the need to consider evaporation of TBT as the chloride as a mechanism of loss...

Applications of chemical vapor generation in non-tetrahydroborate media to analytical atomic spectrometry

“…275 No reagents were required and calibration was achieved by use of CRM-based external calibration. The volatile butyltin species in the headspace above solid sediments was characterized as chlorides by GC-electron impact MS and capillary GC-negative ion chemical ionization MS. 276…”

Atomic spectrometry update. Environmental analysis

“…Studies using solid phase microextraction have shown 31 that tributyltin chloride is sufficiently volatile at room temperature to be sampled from the headspace above saline water, and determined by GC-MS. This work indicates two important findings: that TBT-Cl can be lost from water samples unless they are stored below room temperature; and that the evaporation of TBT-Cl is an important biogeochemical mechanism for the butyltin compounds commonly found in the marine environment.…”

“…The same authors 119 have also described a similar method employing ID in combination with HPLC-ICP-MS detection for the same analytical task. Bancon-Montigny et al 31 demonstrated that TBT chloride could be detected in the vapour phase above PACS-2 sediment after one night of passive sampling, without any heating of the sample. This observation was exploited by Scriver et al, 118 who developed a technique based on in situ trapping of TBT as the volatile chloride using flow injection coupled to ETAAS, after microwave-assisted leaching and continuous purging of the TBT chloride through a gas-liquid separator.…”

Atomic spectrometry update. Atomic mass spectrometry

“…The direct determination of TBT without derivatization has been reported. 375 The TBT in the headspace above aqueous and solid samples was collected using a SPME fibre and desorbed thermally directly into a GC port. Treatment of the GC capillary column with a dilute HBr solution to deactivate sites in the GC column allowed direct injection of the sample species to be made.…”
