General description

BDE No 49 is a ubiquitous environmental contaminant belonging to the class of polybrominated diphenyl ethers. It can find wide applications as a flame-retardants additive in consumer products ranging from textiles to polymers.

Application

BDE No 49 may be used as an analytical reference standard for the determination of the analyte in milk and dust samples using gas chromatography with mass spectrometric detection (GC-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Other Notes

The customer needs to make sure that the standard is homogeneous, this can be achieved by shaking, vortexing , or sonicating the ampoule before opening the ampoule. Care should be taken when opening the ampoule to avoid any injuries from the broken glass.
The standard should be transferred to a clean and appropriate vial or flask using clean pipettes or micro pipettes. The vial should be immediately capped to avoid any loss or evaporation of the solvent.
After opening the ampoule, the standard should not be stored or kept in the ampoule. To preserve the integrity of the product, the standard should be transferred to an appropriate vial that must be capped and stored according to the recommendation on the Certificate of Analysis.
