Abstract

For plastics samples, a method using combustion ion chromatography was selected as a method for rapid low-cost analysis to test whether hazardous substances are contained or not. Using combustion ion chromatography, a verification test for F, Cl and Br compounds generated a linear calibration curve with a correlation coefficient of r² = 0.999~1.000 in the calibration range from 0.5 to 4.0 ㎎/㎏. The detection limits were found to be 0.005~0.024 ㎎/㎏ and quantitative limits were found to be 0.014~0.073 ㎎/㎏. The recoveries of combustion ion chromatography using certified reference material (CRM) were found to be 95.5~104.9%. Based on these results, a proficiency test was conducted together with several laboratories in and out of the country, to make comparative analysis of the results from each laboratory. As a result, the data supported the use of combustion ion chromatography as an effective analysis method to deal with regulations for halogenfree electronic products and for other hazardous substances in the electronic products.
