Dataset to support 'Liquid atmospheric pressure matrix-assisted laser desorption/ionization (LAP-MALDI) mass spectrometry using a commercial ion source and Orbitrap mass analyzer'

As part of the EPSRC project 'A Cost-Effective High-Speed Clinical Diagnostics Instrument for Large Population Screening Based on Novel Liquid AP-MALDI MS Technology', the application of liquid atmospheric-pressure matrix-assisted laser desorption/ionisation (LAP-MALDI) methodology in conjunction with a commercial AP-MALDI ion source coupled to an Orbitrap mass analyser was investigated. The raw data files, including AP-MALDI-Orbitrap, LAP-MALDI-Orbitrap and LAP-MALDI-QTOF data of an 8 peptide mixture, a 3 protein mixture, and a bacterial extract are presented here.
