| Resumen: | This standard specifies a method for the determination of tetraacetyl ethylene diamine (TAED) content greater than or equal to 25g/100g in granules. The TAED granules are dissolved in acetonitrile, the internal standard is added to this solution and finally it is injected to a gas chromatograph. A flame ionisation detector is used for detection. The results are calculated from the peak areas taking into account the response factors that are determined previously. |
