药物和法医分析涉及生物样本，通常是具 有挑战性的复杂基质。PAL系统为活性药物 成分、非法药物、有毒化合物的自动化分 析以及残留物分析提供了行之有效的工作 流程。
活性药品中的亚硝胺备受关注。采用液液体 萃取的PAL System上的全自动样品制备包括涡 流、离心和蒸发，用于直接进样到LCHRMS。
USP 467标准方法控制药品中残留溶剂是制 药行业中最常用的顶空方法。PAL System可 提供高精度的样品制备，用于气相色谱-质 谱联用的顶空分析。
为了在法医实验室分析非法药物，通常要 在PAL System上对尿液或头发样本进行自 动样本制备。干血点分析（DBS）在 PALSystem上完全自动化。此外，微型 SPE（uSPE）也可用于分析血清样本中的 精神活性物质、非法药物控制或TDU疼痛 管理。

Novel Automated Sample Clean-up: First Comprehensive Evalulation of Different Filtration Devices for x-y-z Robots
In our study we evaluate the available filtration options for x-y-z robots and some not-yet commercially available filtration devices prototypes.
Untargeted 2DxLC-Mass Spectrometry using SWATH-DIA-Based Workflow for the Characterization of Lipid Profiles in Plasma Samples
The use of lipidomic analyses based on LC-mass spectrometry has become widespread due to its sensitivity and specificity which provides a broader picture of lipid profiles in biofluids. In this work, we combined an automated sample extraction and a two-dimensional liquid chromatography (2DxLC) system with HILIC-based class separation followed by an orthogonal reverse-phase chromatography with an untargeted SWATH-DIA workflow to accurately annotate phosphatidylcholines (PC), lysophosphatidylcholine (LPC) and etherphosphatidylcholines (PC O-) in human plasma samples.
Automated Parallel Derivatization of Metabolites
For metabolite profiling chemical derivatization has been used to improve MS sensitivity and LC retention. However, for multi-analytes quantification, the number of available isotopically labelled internal standards is limited. And, there is no single workflow which can provide large-scale metabolomics coverage in particular for polar metabolites.
