Introduction<\/h5>\n

The Mass Spectrometry Unit is a cross-disciplinary research support platform offering a range of services accessible to all researchers. Its mission is to drive, promote and carry out high-quality translational research by providing support in the fields of pharmacology, clinical research and proteomics.<\/p>\n

Mass spectrometry is an analytical technique noted for its ability to identify and quantify a wide variety of molecules with great precision and sensitivity, even at extremely low concentrations (sub-femtomolar). Its high specificity allows for the differentiation of structurally similar compounds, whilst its multiplexing capability facilitates the simultaneous analysis of multiple analytes in a single injection.<\/p>\n

The facility\u2019s infrastructure combines micro-scale liquid chromatography with a hybrid triple quadrupole\/linear ion trap mass spectrometer, enabling the identification and quantification of components with high sensitivity in a single analysis using DDA and MRM scanning techniques.<\/p>\n

The range of services is available to staff from both the INCLIVA Foundation itself and other institutions, whether public or private.<\/p>\n<\/div>
