Determination of C2-C12 aldehydes in water by SPME Arrow on-fiber derivatization and GC/MS
应用说明

Determination of C2-C12 aldehydes in water by SPME Arrow on-fiber derivatization and GC/MS

The method employing a SPME Arrow allows for the quantitation of water samples down to 50 ng/L for most of the described aldehydes with good precision.
A previous publication applying traditional standard SPME fibers and GC/MS achieved sensitivities down to 120-340 ng/L in spiked samples for C1, C3-C5

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 Sample Preperation for LC-MS and GC-MS -Solutions for Food and Environmental Analysis

In this presentation we want to discuss an important development and a demand from analytical laboratories about the standardization and the automation of sample preparation procedures for food safety, environmental, the forensic or pharmaceutical analysis.
