RoHS限用物质检测
RoHS指令自2006年7月1日起执行, RoHS指令禁止销售铅、汞、镉、六价铬、多溴联苯、多溴联苯醚六类有害物质超过其最大限量值的产品,根据IEC62321、SJ/T11365-2006等国际国内RoHS相关检测标准,我检验中心最新购入了包括样品前处理的用于RoHS分析的检测设备,正式开展RoHS定量分析检测.
Pb、Hg、Cd的精确分析
根据样品性质和分析元素的不同,参考标准进行样品前处理和被测元素的分析,我检验中心的ICP（Varian 710-ES系列）具有更好的分析能力、更快的分析速度、更低的检出限和更宽的动态线性范围,ICP除了能测定RoHS所限管的物质以外还能测定其它69种元素.
Cr6+的精确分析
The Precise Analysis of Cr6+
参考国际国内标准,对 Cr6+的分析可以利用二苯卡巴肼不与Cr3+反应,只与Cr6+反应形成络合物,在540nm显示特征峰的吸收曲线(紫红色),利用紫外可见分光光度计对Cr6+进行选择分析,我检测中心的UV-Cary50仪器达到了190-1100nm的宽波长范围并且具有极宽的光度线性范围.

Detection of Restricted Substances in RoHS
The directive “The Restriction of the use of certain Hazardous substances in Electrical and Electronic Equipment” （EU Directive 2002/95/EC）was executed from July 1st,2006,RoHS directive prohibits the sales of the products that such six hazardous substances as lead,mercury,cadmium,hexavalent chromium,polybrominated benzene (PBB),polybrominated diphenyl ethers (PBDE) exceed the maximum limited amount value,according to the international and domestic relative detection standards such as IEC62321,SJ/T11365-2006,recently our Inspection and Testing Center purchased the detection equipment for RoHS analysis,including the equipment for pre-treating sample,and officially starts to carry out the quantitative analysis of RoHS restricted substances.
The Precise Analysis of Pb、Hg、Cd
According to the difference of sample’s properties and analyzed elements,referring to the standard the pre-treatment of the sample and the analysis of the measured elements are carried out.The ICP （Varian 710－ES series）our Inspection and Testing Center owns has better analysis capability,faster analysis speed,lower detectable limit,and wider dynamic linear range.Besides the substances that RoHS restricts ICP can be used to detect other 69 kinds of elements.
The Precise Analysis of Cr6+
Referring to international and domestic standards the analysis of Cr6+ can utilize the fact that diphenyl carbazide does not react with Cr3+ and only react with Cr6+ to form complex,which exhibits the absorption curve of the characteristic peak at 540nm (claret),then Cr6+ is selectively analyzed using UV Vis Spectrophotometer.The UV-Cary50 instrument of our Inspection and Testing Center achieves a wide wavelength range of 190-1100 nm,and has extremely wide linear range of luminosity.
