Test Method: SATRA TM277

Determination of organotins

December 2020

SCOPE

This test method is intended to determine the levels of a range of common organotin compounds in a material. The method is applicable to all types of material.

PRINCIPLE

Organotins are extracted from the test specimen using an ethanol/methanol mixture and are then converted to the corresponding tetraalkyl derivative through a reaction with sodium tetraethylborate. The derivatised organotins are identified and quantified using a gas chromatography/mass spectrometry detection technique.
