APPLICATION NOTE #XE-2015-3278Quantitative analysis of RoHS elements and C/ Quantitative analysis ofROHS elements and EDXRF Analyzer：RolSDD传公上网 公限有 1-仅限仪器 Xenemetrix x-RoHs*SDD X-RoHS+SDD EDXRF analyzer APPLICATION NOTE #XE-2015-3278 Quantitative analysis of RoHS elements and C/ Abstract Several electronic and plastic components were analyzed for compliance with RoHS (Cr， Br， Hg， Pband Cd content) on Xenemetrix RoHS* SDD EDXRF analyzer. In addition the Chlorine concentrationwas determined in all samples. Objective To analyse different products for RoHS compliance and for Cl content Background EDXRF is an ideal method for a quick and simple elemental analysis tests for industrial controlpurposes.This analytical technique boasts in being extremely is quick， noninvasive， requiring minmal samplepreparation， and can easily be operated by non-skilled personnel in the productionfinexEDXRF is inparticular very suitable for quick screening of electronic components and plastis pants used in theindustry for RoHS compliance. The RoHS*SDD analyzer has a special userfriend yGUI that provides aquick automatic analysis of almost any sample for RoHS compliance. Analytical Configuration Table 1： Instrumental analytical configuration Instrument RoHS*SDD Anode Mo-Anode X-ray Tube，50w，50W Detector high performance SNicon Drift Detector (SDD) Environment Air Excitation mode Direct excitation w th micro Xray spot (d=1mm on sample) Analysis time 300 secoods Experimental Each component was analyzefanXXenemctrix-RoKS*SDD analyzer using a camera to position thesample inside the small X-ray beam spot(diameter 1 mm on the sample). The pictures of thedifferent samples are shawn in Figure1-11. The RoHS analyzer qualifies the result using the limitsaccording to international RoHS standards RoHS spocities maximunxevels for the six restricted materials： ead(Pb)： <1000 ppm Mercury (Hg)<1000 ppm Hexavalent Chromium： (Cr VI) < 1000 ppm Polybrominated Biphenyls (PBB)： < 1000 ppm PPolybrominaed Diphenyl Ethers (PBDE)： <1000 ppmCCadmium.<100 ppm Table 2： ROHS Screening limits in ppm for regulated elements in various matrices.
