离子色谱法测定食品中的二氧化硫

从中药中提取分离化合物，第一步需要将中药材中的成分用有机溶剂提取出来，包括常规的有机溶剂浸泡，超声提取，超临界提取和加速溶剂萃取（Aseeker-600型加速溶剂萃取仪）等，得到一份总提物。

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.
