食用油苯并芘检测方法

Stylus-based surface profiling is a standard technique for accurate, repeatable surface shape, topography and step height measurement in applications ranging from semiconductor R&D to solar cell QC.

纯水是制备溶出溶剂或生物相关溶液的重要成分，因此水质的好坏会影响结果。一旦水质选择不当，就会引入污染物，主要有以下几种类型。使用高质量纯水来制备溶出溶剂，是获取精确、可重现结果并满足监管要求的重要保障。

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.
