Quantitative Determination of Halogen Elements in Resin



The quantitative determination of halogen elements, including Br which is subject to RoHS and other regulations, can be carried out by combustion gas absorption and ion chromatography analysis.

Example of analysis: Determination of total Br amount in a plastic standard material

Method: A sample is burned at 900℃ in a current of Ar+O2, and the halogen component thus
     gasified is caused to be absorbed into an aqueous absorbent. The resultant absorption
     liquid is analyzed by ion chromatography to determine the amount of halogens.
