环己烯中的溴值

1、恒温槽采用铝块加热的方式，50~200℃范围内进行高精度温度调节。 2、反应柱分为内径3·5·10mmX长度50·100mm的六个种类，材质分为不锈钢材质和玻璃材质，玻璃反应柱适用于酸性样品的反应。 3、反应柱在恒温槽内的固定操作十分简单，只需一个拉杆动作即可完成安装。 4、样品导入端分为液相反应用和气液反应用2个种类（选购） 5、氢气、氧气、二氧化碳气的气体反应用大流量控制单元也可配备（选购）

Lipid profiling from complex lipid extracts can be a challenging and time consuming task. The high complexity of samples and co-elution of isobaric or isomeric compounds complicate the confident annotation of lipids. The presented 4D-Lipidomics workflow simplifies and streamlines the annotation and validation process using mobility-enhanced MS data.

Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.

磷酸中杂质的监测对于其应用至关重要。除其它参数外，总有机碳还作为总量参数应用于质量控制中，用于评估有机杂质的整体污染情况。 本文主要对紫外-过硫酸盐氧化法和NDIR检测器对磷酸中TOC杂质的全自动质量控制进行验证。
