Agilent 7890A/NPD/5975C/DRS GC/MSD在法医毒物快速分析中的应用

医疗污水包含了多种细菌、重金属、有机溶剂及酸碱溶液等生化有毒有害物质。如上述物质直接排放，将会对自然生态及人类生活环境造成危害。我国对医疗污水有清晰的排放标准。连华科技对于《医疗机构水污染物排放标准GB18466-2005》中所涉及的参数，多款便携及实验室仪器及耗材可满足检测需求

金属检测技术的局限性之一是对于像电线和大头针这样相对比较小的、长条形金属异物就很难检测出来。这些类型的污染物通常表现出“方向效应”，即金属探测器所检测到的信号很大程度上取决于污染物与探测孔的方向关系。方向效应给金属检测系统带来了挑战——这一挑战乍一看并不是那么严重，但事实上它可能会给消费者的安全以及品牌声誉带来严重的影响和危害。

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.
