Great take care should be necessary for high brominated compounds
because of poor linearity
Necessary isotope dilution technique by GC-HRMS
for high bromine PBDE,PBB analysis

�� Not stable : Active compounds
Photo degradation, debromination
Thermally unstable
Higher Br comp. GC column adsorption &
bad linearity
