ProcessInstruments公司推出一种检测烯烃含量的新技术
Process Instruments公司推出一种检测煤气或其它燃料中烯烃含量的新技术 检测烯烃在汽油或其他燃料中含量的方法已经有了新的突破。目前ASTM标准里检测烯烃含量的方法只包括荧光指示剂方法和超临界流体色谱法，但是这两种测量方法既不准确也费时。拉曼光谱非常适用于烯烃的检测，因为拉曼光谱对不饱和分子的散射信号尽在1640～1690cm-1波长范围内，此光谱区域不包含其它燃料成分只包括烯烃中组分的信号。该方法不需要具备常规的分离技术。拉曼光谱检测烯烃含量的方法提高了原来的技术手段，因为该方法不需要对样品进行前处理工作，并且是一台安全性能高的分子仪器。该仪器可以自动校准，开机5分钟后便可进行检测，精确率非常高。 欲了解详细信息，请登录：http://www.process-instruments-inc.com/pages/pump.html#auto......阅读全文

红外吸收光谱
大多数材料会吸收红外光谱区域中波长为0.8 µm至14 µm的电磁辐射，这些波长是材料分子结构的特征。红外吸收光谱法是一种常见的化学分析工具，用于测量已穿过样品的红外光束的吸收率。红外光谱中吸收峰的位置是样品化学成分或纯度的特征，吸收峰的强度与该峰为特征的物质的浓度成正比。 红外光谱可用于气体
