Water quality. Determination of tributyltin (TBT) in whole water samples. Method using solid phase extraction (SPE) with SPE disks and gas chromatography with triple quadrupole mass spectrometry
This Technical Specification specifies a method for the determination of tributyltin cation (TBT) in whole water samples. It is applicable to the analysis of TBT in surface water, which may contain suspended particulate matter (SPM) up to 500 mg/l (whole water samples), groundwater, drinking water and seawater. The working range is 0,04 ng/l to 20 ng/l. The LOQ will be mainly determined by the blank value obtained during validation of this method. NOTE 1 The method has been successfully applied to seawater samples during method development, but sea water samples were not included in the interlaboratory comparison. NOTE 2 In this document TBT is synonymous for tributyltin cation. NOTE 3 Near the lower limit of the working range the measurement uncertainties may be higher.
