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 spectrometry1 Scope 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
