GB/T 5009.215-2008 Determination of organotins in foods
This standard specifies the method for detecting the content of organic tin in food by gas chromatography with a pulsed flame photometric detector.
This standard is applicable to the determination of dimethyl tin, trimethyl tin, monobutyl tin, dibutyl tin, tributyl tin, monophenyl tin, diphenyl tin, and triphenyl tin in samples such as fish, shellfish, wine, and soy sauce.
The quantitative limits (μg/kg) for the determination of food samples in this standard are as follows: dimethyl tin 0.5; trimethyl tin 1.2; monobutyl tin 1.5; dibutyl tin 0.5; tributyl tin 0.6; monophenyl tin 1.7; diphenyl tin 0.8; and triphenyl tin 0.8. The detection and quantitative limits of the method depend on various factors such as the sensitivity of the instrument used, the amount of sample taken, and the level of interference.
