Pharmaceutical and forensic analysis deal with biological samples, typically with challenging, complex matrices. PAL Systems deliver proven workflows for the automated analysis of the active pharmaceutical ingredients, illicit drugs, toxic compounds, and also residue analysis.
Nitrosamines in active pharmaceutical products are of high concern. The fully automated sample preparation on the PAL System with liquid/liquid injection (LLE) comprises vortexing, centrifugation and evaporation for a direct injection into LC-HRMS.
The control of residual solvents in drug products applying USP 467 standard method is the most used headspace method in pharmaceutical industry. The PAL System delivers highly precise sample preparation for headspace analysis with GC/MS.
For the analysis of illicit drugs in forensic labs often urine or hair samples are subjected to automated sample preparation on the PAL System. The dried blood spot analysis (DBS) is perfectly automated on the PAL System. Also the micro-SPE (µSPE) finds application e.g. for the analysis of psychoactive substances from serum samples, illicit drug control or TDU pain management.

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.
