RoHS标样
RoHS standard sample
  RoHS校准标样包括受RoHS指令限制的元素:汞、铅、镉以及溴和铬,溴和铬分别代表PBDE/PBB和六价铬这两种限制物质。标样还包括六种通常被用作聚烯烃添加剂或填充剂的元素:砷、氯、锑、锡、锌和硫。  
RoHS calibration including RoHS command limit element: Mercury, lead, cadmium and bromine and chromium, bromine and chromium on behalf of PBDE / PBB and six chromium two restricted substances. The sample includes six kinds of commonly used polyolefin additives or fillers elements: arsenic, antimony, tin, zinc chloride, and sulfur. 
美国加联仪器有限公司    
The United States and United Instrument Company Limited
美国加联推出新的RoHS校准标样,为满足全球正在推行的各种RoHS指令的要求提供了完整的解决方案。开发了用于X射线荧光(XRF)分析的RoHS校准标样,可以保证广泛含量范围内(从低ppm到低百分比)分析的最高准确度和精度。此外,从成分来看,新校准标样与欧盟官方标样最接近。RoHS校准标样非常适用于分析烯聚合物及其他聚合物,使美国加联可以为创新行业提供更多符合RoHS、WEEE和ELV等环保法规要求的解决方案。   
The United States company launches new RoHS calibration, in order to meet the world are pursuing a variety of RoHS instructions required to provide a complete solution. Developed for X ray fluorescence ( XRF ) analysis of the RoHS calibration, can guarantee the wide concentration range ( from the low ppm to low percentage of ) the highest accuracy and precision analysis. In addition, from the point of the elements, the new calibration samples and standard samples of the closest official eu. RoHS calibration is very suitable for the analysis of olefinic polymer and other polymers, so that the United States and United for the creative industries to provide more in line with RoHS, WEEE and ELV environmental regulations and requirements of the solution. 
使用这些标样可以根据精确的化学含量对测量出的XRF强度进行校准。通过这样的校准,能够以最大准确度和精确度确定未知聚合物样品的成分。   
The use of these samples according to the precise chemical content on the measured XRF strength calibration. Through such calibration, can in order to maximize the accuracy and precision of determination of polymer sample composition.

美国加联提供的标样的元素分布同质性极高,而且,由于标样中的各种元素含量经过精挑细选且不具关联性,因此可以准确确定谱线重叠校正系数。校准标样程序包包含四个多元素聚乙烯标样(每个标样的元素含量和重复项各不相同)和一个空白样。
The United States of America plus joint provided samples of the element distribution are very homogeneous, but, due to the various elements in the sample content are carefully selected and no connection, therefore can accurately determine spectra overlap correction coefficient. Calibration package contains four elements polyethylene samples ( each sample element content and duplicates each are not identical ) and a blank sample.
