气相色谱法同时测定玉米中辛酰溴苯腈和2,4-滴丁酯的残留

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

Millipak® Final Fill过滤器的特殊层叠式设计可最大程度地减少残留体积，从而增加产品回收。过滤器吹扫亦可有效降低折叠膜和层叠式过滤器使用后的残留量。

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.
