产品名称： 阻燃剂检测标准品 规　　格： MS 产品备注： 产品类别： 标准品 美同达科技有限公司 产 品 说 明 PBDEs由于其阻燃效率高，热稳定性好，用量小，对材料影响小，价格便宜为广泛的应用于电子、电器、化工、纺织、石油等领域。但是由于PBDEs具有挥发性，可以散逸到空中，随大气长距离迁移。且具有亲脂性，可以随着食物链生物放大。目前PBDEs在环境和人体中污染程度的增长速度引起社会关注。欧盟在2006年正式启用RoHS指令对铅、汞、镉、六价铬、PBBs、PBDEs进行严格限制，同年我国也颁布了《电子资讯产品污染控制管理办法》，对铅、汞、镉、六价铬、PBBs、PBDEs等试剂的添加及应用进行限制和监管。 北京美同达科技有限公司推出的阻燃剂产品套包，将阻燃剂检测的相关170多种的PBDE同系物，配套使用的PBDE代谢物、PAHs、氘代内标物及配套用的耗材配件全部网罗其中，随订购的标样附带质检报告、材料安全数据卡，并且可以为用户提供专业标样的定制服务。 部分产品清单如下： Mercury，汞 Lead，铅 4-Bromophenoxybenzene，溴联苯醚 2,5-DIBROMODIPHENYL ETHER，二溴联苯醚 2,4,4?TRIBROMODIPHENYL ETHER，三溴联苯醚 2,2',4,4'-Tetrabromodiphenyl ether，四溴联苯醚 2,2',4,4',5-Pentabromodiphenyl ether，五溴联苯醚 2,2',4,4',5,6'-Hexabromodiphenyl ether，六溴联苯醚 2,3,3?4,4?5?6-HEPTABROMODIPHENYL ETHER，七溴联苯醚 2,2?3,3',4,4?6,6'-OCTABROMODIPHENYL ETHER，八溴联苯醚 2,2',3,3?4,4?5,5',6-NONABROMODIPHENYL ETHER，九溴联苯醚 Decabromodiphenyl oxide，十溴联苯醚 4-Bromomethyl-2-cyanobiphenyl，溴联苯 2,4-DIBROMOBIPHENYL，二溴联苯 2,2',5-TRIBROMOBIPHENYL，三溴联苯 2,2?4,4?TETRABROMODIPHENYL ETHER，四溴联苯 2,2',4,5,5'-PENTABROMOBIPHENYL，五溴联苯 HEXABROMOBIPHENYL，六溴联苯 DOW FR-250 (OCTABROMOBIPHENYL)，七、八、九溴联苯混合物 DECABROMOBIPHENYL，十溴联苯
