In this paper the suitability of reagent water for LC-MS biomedical analyses will be evaluated and the role of water quality in achieving sensitive and reliable LC-MS analyses will be discussed. Furthermore, since quality assurance is one of the key requirements in the clinical laboratory, a modern solution for data management will be introduced in order to address this need.

Non-targeted metabolomics study on cell extracts were carried out with a UHPLC-HILIC-MS setup. The 1.8 µm iHILIC-Fusion HILIC column used has a multimodal separation principle that can efficiently separate a large quantity of polar metabolites based on their multiple physicochemical properties. Accordingly, its separation efficiency of intra-class metabolites is higher than other HILIC columns used in our tests.

This application note outlines a QuEChERS method for the simultaneous analysis of cannabis for 47 pesticides, 5 mycotoxins and 3 cannabinoids. Sample purification is carried out using UCT’s new cleanup product SpinFiltr™, which combines the convenience of classical dispersive-SPE (dSPE) with an ultrafiltration tube containing a 0.2 μm filter membrane to simultaneously remove unwanted matrix components and filter the sample prior to LC or GC analysis.
