Description 40-44
A method is described for sample preparation by gas chromatography in
biological samples. TBT was extracted from samples as chloride under the acidic
condition of HCl and was detected by GC-ECD system using an apolar capillary column doped with
a dilute HBr-methanolic solution. Derivatization step has been eliminated from sample
preparation procedure, but doping of the GC-ECD system with a dilute
HBr-methanolic solution has been used to detect the TBT chloride and
triphenyltin (TPhT) directly by halogen exchange from chloride to bromide. This combination made it
possible to determine TBT as less than the ngg-1 level in fish
tissue.
