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.

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。
