Content Handbook F

 

Ouline of method

151.1 TCDD in 2,4,5-T technical

TCDD is extracted from 2,4,5-T constituents with hexane and cleaned up by liquid chromatography. It is subsequently separated by capillary gas chromatography with detection by low resolution mass spectrometry.

151.2 TCDD in 2,4,5-T technical esters

The TCDD is separated from 2,4,5-T ester constituents by liquid chromatography and is subsequently determined by capillary gas chromatography with detection by low resolution mass spectrometry.

 

 

Scope

151.1 TCDD in 2,4,5-T technical

This method is applicable to the determination of 2,3,7,8-tetrachlorodibenzo-pdioxin (2,3,7,8-TCDD) in 2,4,5-trichlorophenoxyacetic acid.

151.2 TCDD in 2,4,5-T technical esters

This method is applicable to the determination of 2,3,7,8-tetrachlorodibenzo-pdioxin (2,3,7,8-TCDD) in 2,4,5-trichlorophenoxyacetic ester.
