The toxicity of hexabromocyclododecane (HBCD or HBCDD) and its harm to the environment are current concerns. Here, Alfa Chemistry provides HBCD analysis and testing services to help you identify the content of brominated flame retardant HBCD in plastic products.
HBCD is a brominated flame retardant that is primarily used in extruded (XPS) and expanded (EPS) polystyrene foams used as insulation in the building industry. However, HBCD is persistent, toxic and ecotoxic, thus its content needs to be analyzed and regulated. As an alternative, a special polymer brominated flame retardant (Polymeric FR) was developed. It is also necessary to identify and differentiate between the two brominated flame retardants in plastics.
Alfa Chemistry is able to identify and detect HBCD in extruded (XPS) and expanded (EPS) polystyrene foam using a variety of analytical methods. The following are two commonly used qualitative and quantitative analysis methods.
X-ray fluorescence spectrometry (XFR) analysis
Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) analysis
Correlation of bromine content based on HBCDD quantified by LC-MS/MS and XRF analysis.

Other HBCD detection methods are also under continuous development, such as nuclear magnetic resonance method can be used to identify HBCD and Polymeric FR , gas chromatography-mass spectrometry can be used to determine the content of HBCD. For example, Tianao Mao et al. determined the HBCD content in EPS and XPS polystyrene foam by gas chromatography-mass spectrometry, and the results are as follows.
